07-002-05 HYDRAULIC RADIATOR COOLING FAN SYSTEM DIAGNOSTIC CHECK CHART AID

Date: 06/25/05

Model year(s): 2005

Description: The 5.7L hydraulic cooling fan is integral to the fan shroud and is located between the radiator and the engine.

The power steering pump supplies the hydraulic fluid and pressure to rotate the cooling fan blade, while the electrical part of the fan is controlled by the Front Control Module (FCM).

The hydraulic fan drive (motor) consists of the three major following components:

  • Steering flow control valve
  • Fan control valve
  • Two stage G-rotor hydraulic drive

The hydraulic fan and drive is not serviceable, except for the fan motor solenoid. Therefore any failure of the fan blade, hydraulic fan drive (except solenoid) or fan shroud requires replacement of the fan module. Because the fan blade and hydraulic fan drive are matched and balanced as an assembly and servicing either separately would disrupt this balance.

CAUTION: Do not attempt to service the hydraulic cooling fan or fan drive separately, they are serviced as an assembly. Failure to do so may cause severe damage to the hydraulic cooling fan assembly.

Operation: The hydraulic radiator cooling fan used on the 5.7L gasoline and 3.0L diesel engines replaces both the electric fan and the engine driven mechanical fan. This provides 5.7L and 3.0L equipped vehicles with heavy trailer towing capability while at the same time reducing unnecessary power drain on both the engine and the vehicles electrical system.

Hydraulic fan strategy: The hydraulic radiator cooling fan is controlled by the Front Control Module (FCM). A Pulse With Modulated (PWM) signal from the FCM controls the fan speed. There are three inputs to the FCM that determine what percentage of fan speed is required by the vehicle. These inputs are:

  • Engine Coolant Temperature
  • Transmission Oil Temperature
  • A/C System Pressure
By monitoring the desired operating parameters for these three inputs, the FCM can determine if cooling airflow is required. If airflow is required, the FCM will slowly speed up the fan until the parameter(s) are under control. Once the temperature or pressure is reduced to within operating parameters the fan will speed up, slow down, or hold its speed to maintain the temperature/pressure requirements.

NOTE: Even if the FCM is not requesting fan on operation, the fan blade will usually spin between 100 and 500 RPM when the vehicle is at idle.

Activating the hydraulic fan with the scan tool (starscan®): Under the Engine Systems test heading, there is a subheading. “Hydraulic fan solenoid test”, that has the selections, on/off. Activating the fan with the StarSCAN® will run the fan at 100% duty cycle, which will help troubleshoot any system problems, and also help with the hydraulic system deaeration procedure.

NOTE: Engine must be running to activate the fan with the StarSCAN®.

Radiator cooling fan hydraulic fluid path: Hydraulic fluid is pumped by the power steering pump though a high pressure delivery line to the fan drive motor. As fluid is diverted through one or both G-rotor stages, rotational motion is created as fluid moves from the high-pressure (inlet) side of the motor to the lower-pressure (high pressure outlet) side. Fluid exiting the drive motor is divided into two paths. In path one, fluid continues through a high pressure delivery line to the vehicle steering gear to provide steering assist. This fluid then exits the steering gear under low pressure and travels through a low pressure line to the power steering fluid cooler to be cooled before being returned back to the power steering fluid reservoir. In path two, excess fluid travels through a low pressure line back to the power steering pump fluid reservoir.

NOTE: There is a steering flow control valve located in the fan drive motor. This valve operates like the flow control valve found in the typical power steering pump. A failed pump and/or fan drive can produce contamination that may cause the steering flow control valve to stick.

08-001-04 FRONT PASSENGER AIRBAG SAFETY PRECAUTIONS

Date: 01/06/04

Model year(s): 2005

Description: This bulletin involves warnings prohibiting modifications to the front passenger seat assembly, related components, or trim cover.

NOTE: This bulletin applies to vehicles equipped with the Occupant Classification System (OCS) for the right front passenger airbag. The front passenger seat assembly contains critical components that affect the front passenger airbag deployment. Correctly functioning front passenger seat components are critical for the Occupant Classification System (OCS) to properly classify the front passenger and calculate the proper airbag deployment. Do not make any unapproved modifications to the front passenger seat components, assembly, or to the trim cover.

NOTE: Always follow the service information in TechCONNECT for the correct repair and/or diagnostic procedures when servicing the front passenger seat assembly, related parts, or trim cover.

Unapproved modifications or service procedures to the front passenger seat assembly, its related components, or trim cover may inadvertently change the airbag deployment in case of a frontal crash. THIS COULD RESULT IN DEATH OR SERIOUS INJURY TO THE FRONT SEAT PASSENGER IF THE VEHICLE IS INVOLVED IN AN ACCIDENT. A modified vehicle may not comply with required Federal Motor Vehicle Safety Standards (FMVSS).

08-035-04 NO SOUND FROM RADIO SPEAKER/AMPLIFIER WHEN IOD FUSE IS INSTALLED

Date: 10/25/04

Model year(s): 2005

Description: This bulletin applies to vehicles equipped with Boston Accoustic Speakers (sales code RC6).

Details: A technician or customer may experience a condition where no sound is generated by the audio system (the radio amplifier and speaker) when the Ignition Off Draw (IOD) fuse is first installed. During this condition the radio display will illuminate as designed and the radio controls will appear to function correctly.

This condition may be experienced when a vehicle predelivery is being performed by the dealer technician or any time after the IOD fuse has been reinstalled following prior removal.

This condition may be caused by the radio amplifier. The radio is powered by the IOD fuse and will stop sending command messages to the radio amplifier when the IOD fuse is removed or when it is turned off. The radio amplifier is not powered by the IOD fuse and remains awake for a period of time waiting for command messages from the radio. Without command messages from the radio, the radio amplifier will remember the last known command message status from the radio which was “radio off”. The radio amplifier will store the “radio off” command and may not generate sound until the amplifier is reset.

The radio amplifier can be reset so that it is operational using one of the following two procedures.

Radio amplifier reset procedure 1 (induced “sleep” mode):

1. Verify that the IOD fuse is fully installed.

2. Disconnect any diagnostic scan tools from the vehicle. Diagnostic scan tools when connected to the vehicle may keep some modules and the communication bus from going into “sleep” mode.

3. Turn the ignition switch to the “OFF” position and remove the ignition key.

4. Make sure all doors, hood, liftgate are closed. Make sure all accessories are turned off. Open the driver side door and close it.

5. Wait one minute before performing any activity to the vehicle to allow the vehicle modules and communication bus to go into “sleep” mode.

Radio amplifier reset procedure 2 (battery disconnect):

1. Verify that the IOD fuse is fully installed.
2. Disconnect the negative battery terminal from the battery.
3. Wait five (5) seconds.
4. Connect the negative battery terminal to the battery.

Model year(s): 2005

NOTE: This bulletin applies to vehicles equipped with Auto High Beam “Smart Beam” (sales code LMS) built prior to December 24, 2004.

Description: This bulletin involves selectively erasing and reprogramming the Front Control Module (FCM) with new software.

Details: The customer may experience a condition where the vehicle fog lamps fail to turn off as intended once the ignition key is turned to the OFF position and the customer exits the vehicle. This condition may be intermittent in occurrence. The condition will occur only when: the fog lamp switch is on, the automatic headlamp switch is on, and the Auto High Beam system is operational (has met all operating parameters that will allow the system to enable).

If a subject vehicle is in for service or is in dealer inventory, perform the Repair Procedure.

Using a Scan Tool (StarSCAN) with TechCONNECT or the appropriate Diagnostic Procedures, verify all systems are functioning as designed. If DTCs are present record them on the repair order and repair as necessary before proceeding further with this bulletin.

08-004-05 PARK ASSIST SYSTEM - FALSE OBJECT DETECTED AND ERRONEOUS DTC'S

Date: 01/26/05

Model year(s): 2005

NOTE: This bulletin applies to vehicles equipped with the Park Assist system (sales code XAA) and built prior to January 15, 2005.

Description: This bulletin involves removing the rear fascia and replacing all four Park Assist sensor spacers.

Details: The customer may experience an intermittent erroneous warning (LED illumination and/or audible alarm) from the Park Assist system. When the customer places the vehicle shifter into the Reverse position, the Park Assist system may falsely indicate that an object is behind the rear of the vehicle and is within detection range of the system. One or both red LED's may be on constantly while the vehicle is in reverse. The condition may be accompanied with Park Assist system Diagnostic Trouble Codes (DTC), and a “Service Park Assist System” message may be displayed by the Electronic Vehicle Information Center (EVIC) in the instrument cluster.

Diagnosis: Normal accumulation of debris, snow, or ice (even a thin layer accumulation) on the face of the sensor may cause the above condition. Therefore it is important to first verify that the chrome faces of all four rear Park Assist sensors are clean of debris, snow, and ice.

If the rear park assist sensors are clean of debris, snow, and ice, then the false object detected condition may be caused by a possible signal reflection from the rear fascia chrome applique. The sensor has a spacer to properly position it relative to the rear fascia and applique to prevent possible erroneous signal reflections. The erroneous signal reflection from the chrome applique may generate DTC's.

Verify if one or more of the following Park Assist Diagnostic Trouble Codes (DTC) are present:

  • B122F - PTS Sensor 7 Ring Time Too Long.
  • B1234 - PTS Sensor 8 Ring Time Too Long.
  • B1239 - PTS Sensor 9 Ring Time Too Long.
  • B123E - PTS Sensor 10 Ring Time Too Long.

If one or more of the above Park Assist system related DTC's have occurred and the rear sensors are known to be free of debris, snow, and ice when the condition occurs, then perform the Repair Procedure.

Parts required:
6x P/N 06500911 Rivet, Black Plastic
2x P/N 05159077AA Clip, Fascia - Under Tail Lamp
4x P/N 05159096AB Spacer, Park Assist Sensor

08-021-05 POOR RADIO RECEPTION - SIGNAL MAY GROUND AT ANTENNA BASE DUE TO METAL DEBRIS

Date: 04/13/05

Model year(s): 2005

NOTE: This bulletin applies to vehicles built prior to March 20, 2005

Description: This bulletin involves applying a specific size strip of electrical tape over top of the antenna base insulator. The tape will prevent the radio signal, from the insulated brass center conductor, from electrically grounding to the antenna base. The antenna base is already grounded to the vehicle body.

Details: The customer may notice that AM or FM radio station reception may be weaker than normal. This condition may include: static, reduced station range, or poor SEEK mode performance. This condition may be caused by a weak antenna signal. Part or all of the antenna signal may be grounding (lost) prior to receipt of the full signal at the radio.

The signal from the insulated antenna mast may be grounding to the already grounded antenna base.

The antenna mast connects to the threaded brass center conductor. The bright chrome antenna cap nut threads onto the brass center conductor. The act of threading the cap nut onto the brass center conduct may create and/or loosen metal filings. Each time the cap nut is threaded onto the center conductor additional metal filings may be produced.

A black insulator is molded into the antenna body. The insulator is used to isolate the brass center conductor (antenna mast signal) from the body grounded cast metal housing of the antenna base. Brass thread filings may fall from the center conductor and may create a ground path across the top surface of the antenna base insulator. The metal filings may be a “trail” of fine pieces of brass and/or thin strips of brass thread shavings. If present, the filings may move during vehicle use and cause intermittent signal reduction or loss.

Diagnosis: If the customer experiences one of the above conditions, perform the Repair Procedure.

NOTE: This bulletin applies only to the AM and/or FM radio modes. Satellite radio is not addressed by this bulletin. This repair should be performed before further radio reception diagnosis is performed or radio replacement is considered.

Repair procedure:

1. Disconnect and isolate the negative battery cable from the battery.
2. Open the right front door.
3. Remove the antenna mast from the antenna base.
4. Remove the chome antenna cap nut and black plastic trim ring.
5. Position the antenna base in the A-pillar opening created by the open door.
6. Thoroughly clean the antenna cap nut and the entire antenna base of any brass filings. Verify that no brass filings are present on the top surface of the molded-in black insulation in the antenna base
(Fig. 1).

NOTE: The cap nut, center conductor, and the antenna base insulator must be free of any metal filings.

7. Locate the two locating tabs used to index the plastic trim ring to the antenna base (Fig. 2).
8. Install a 6.5mm x 55 mm (¼ in. x 2¼ in.) strip of electrical tape around the antenna base covering the molded-in insulator. Use the top of the two locating tabs as a guide for the lower side of the tape strip.
9. Once the tape is installed around the antenna base, carefully form the tape so that it takes the shape of the circular step around the antenna base.
10. Install the antenna base to the right fender.
11. Install the plastic trim ring to the antenna base.
12. Carefully hand thread the chrome cap nut as far as possible onto the antenna base. Tighten the cap nut to 4.5 Nm (40 in. lbs.). Verify that the cap nut is properly tightened.
13. Install the antenna mast to the antenna base.
14. From the A-pillar / right door opening, reposition the sound insulating foam panel between the inner and outer right fender (if equipped).
15. With a trim stick remove the right instrument panel side trim cover. Locate the antenna harness and connector. Disconnect the antenna side lead from the antenna harness connector. The conductors at the end of the antenna lead will be measured for resistance.
16. Using an ohmmeter, measure the resistance at the antenna lead connector between the center conductor and the grounded metal shell of the connector (Fig. 3).
17. Verify that there is NO continuity between the center conductor and the metal shell. The resistance should be greater than 1 Megaohms.
18. Connect the antenna lead to the antenna harness connector and install the right side instrument side panel trim cover.
19. Connect the negative battery cable to the battery and set the vehicle clock to the correct time.

Parts required:
Electrical Tape - Create a tape strip that is 6.5mm x 55 mm (¼ in. x 2¼ in.)

08-037-05 SMARTBEAM SYSTEM - DIAGNOSTIC TIPS

Date: 07/27/05

Model year(s): 2005

NOTE: This bulletin applies to vehicle equipped with the SmartBeam high beam headlamp system (sales code LMS).

Description: This bulletin involves diagnostic tips to address possible SmartBeam concerns.

Details: A quality analysis of SmartBeam system related repairs has revealed that a number of repairs may not have been necessary.

It is important to understand that the SmartBeam system, when activated, ONLY controls the high beam portion of the headlamp system. The SmartBeam system varies the high beam headlamp illumination intensity. The variation in high beam headlamp illumination intensity will range from a low beam level headlamp illumination intensity all the way to a full high beam headlamp illumination intensity. SmartBeam also controls the high beam headlamps from a high beam level of lamp illumination intensity down to a low beam headlamp illumination intensity, and any level of headlamp illumination intensity in between.

Before performing any diagnostics:

  • Verify that the StarSCAN tool is operating with the latest update scan tool software.
  • Check for any aftermarket or installed options that might be blocking the SmartBeam camera or is attached to the rear view mirror. Remove or relocate any obstructions.


The following are some diagnostic tips when reviewing symptoms that may relate to the SmartBeam system:

ISSUE: The LED on the rear view mirror is flashing/blinks or LED flashes initially at start up and then remains on constantly (illuminated).

DIAGNOSTIC TIP:

1. A continuously flashing LED is NORMAL when the SmartBeam system has detected system problem. DO NOT REPLACE THE MIRROR for a continuously flashing LED. The flashing LED is providing information that can be used to diagnose a possible problem.

The following describes what each LED flashing sequence means.

a. Continuous Flashing - 1 flash per second - this indicates that the mirror is in “Aim Mode” and is waiting to be calibrated. The SmartBeam aiming procedure should be performed. Refer to TechCONNECT, select the SERVICE INFO tab, 8 - Electrical, Lamps/Lighting - Exterior, SmartBeam, Standard Procedure.

b. Continuous Flashing - 2 flashes per second - this indicates that the last attempt to calibrate the mirror has failed. This can be corrected by correctly performing the SmartBeam aiming procedure. Refer to TechCONNECT, select the SERVICE INFO tab, 8 - Electrical, Lamps/Lighting - Exterior, SmartBeam, Standard Procedure.

c. A series of flashes at initial ignition on (start up), followed by a STEADY ON LED illumination. These flashes can indicate a SmartBeam hardware failure that may require the mirror to be replaced. Do not confuse the initial flashes followed by a steady on LED for a continuously flashing LED. If a mirror is replaced due to a short series of flashes at ignition on followed by a steady on LED, count the number of initial flashes that occur prior to the LED remaining on constantly. Record the number of flashes on the repair order. Refer to TechCONNECT, select the SERVICE INFO tab, 8 - Electrical, Lamps/Lighting - Exterior, Diagnostics & Testing, DTC Codes, SmartBeam, Lamps/Lighting - Exterior.


ISSUE: Headlamps are coming on during daylight hours or the dash lights and/or Navigation system is dimming during daylight hours.

DIAGNOSTIC TIP:

Refer to Service Bulletin 08-010-05. DO NOT REPLACE THE MIRROR. This issue is a low beam illumination problem with the headlamp system. The rear view mirror component of SmartBeam does not control the low beam Automatic On (and Off) portion of the headlamp system. The SmartBeam system ONLY controls the headlamp high beams. Replacing the mirror will not correct this issue.


ISSUE: UConnect feature does not work or the handsfree cell phone will not connect.

DIAGNOSTIC TIP:

Refer to Service Bulletin 08-013-05 and any other published service related bulletin(s). For UConnect, the rear view mirror only contains the two user interface buttons and the microphone. The buttons and microphone have a very low failure rate. Most of the UConnect system is controlled by the Hands Free Module (HFM). Always attempt to duplicate the customer's concerns with a “known good” Bluetooth cell phone. Refer to TechCONNECT, select the SERVICE INFO tab, 8-Electrical, Navigation/Telecommunication.

Model year(s): 2005-2006

NOTE: This bulletin applies to vehicles equipped with UConnect Hands Free Communications (sales code RSP) that were built prior to October 02, 2005.

Description: This bulletin involves flash reprogramming the Hands Free Module (HFM) module.

Details: The Hands Free Module (HFM) fails to operate causing the UConnect Hands Free Communications system to not respond when system activation is attempted by the customer. Further diagnosis may reveal that when the StarSCAN® scan tool is used to read Diagnostic Trouble Codes (DTC's) the tool indicates that the module is not responding. Other modules on the bus may display loss of communication with the HFM. If the Hands Free Communication system is unresponsive then the HFM may require electronic reset.

Diagnosis: Attempt to reset (power reset) the HFM as follows:

1. With the ignition switch in the “Off” position, remove the “Ignition Off Draw” (IOD) fuse and wait 10 seconds.
2. Install the IOD fuse.
3. Turn the ignition to the “On” position (engine not running).
4. After the module is reset, press the “Phone Button” on the rear view mirror to activate the UConnect Hands Free system and to verify proper system operation

14 Fuel

14-001-06 LOOSE FUEL CAP MESSAGE OR MIL ILLUMINATION FOR TROUBLE CODE P0457

Date: 01/21/06

Model year(s): 2005-2006

Description: This bulletin applies to all vehicles equipped with a gasoline engine.

NOTE: Do not replace the gas cap if only DTC P0457 - Evap System - Loose Fuel Cap is present. Discussion: Starting with the introduction of 2005 model year vehicles a new diagnostic trouble code (DTC) P0457 - Evap System - Loose Fuel Cap was introduced. Also added to some vehicles was an instrument cluster message in the odometer display or message center (EVIC) that alerts the driver that the gas cap is loose.

The PCM monitors the fuel level for a "significant" change in either direction and remembers that this has recently occurred. A loose fuel cap DTC, cluster message or message center message matures when the check for the EVAP system large leak condition fails after the fuel level change event. If a leak of greater than 0.090" is observed after a fuel level change, a loose cap diagnostic single trip failure is stored and the cluster message or message center message is displayed even though a DTC may not yet be present. DTC P0457 - Evap System - Loose Fuel Cap is stored and the MIL illuminated after 2 cold start failures of the large leak diagnostic checks following a fuel change event. Only the passing of one of the 3 EVAP system diagnostic routines large leak, small leak or loose gas cap) by the PCM will validate that the cap is no longer loose and turn off the MIL light or message.

For 2007 model vehicles DTC P0457 - Evap System - Loose Fuel Cap will be stored and the MIL illuminated after 3 cold starts.

To clear the gas cap loose message from the odometer or message center ensure the gas cap is tight and let the vehicle run the small leak diagnostic routine. The small leak diagnostic routine will pass a sealed system after an 8 hour soak and a negative 3° C change in fuel temperature from the last key cycle.

NOTE: A heated garage may effect the small leak diagnostic routine. To clear the gas cap loose message from the odometer or message center and matured DTC (MIL light) diagnose and repair the leak and then erase DTC's with the DRB III®/StarSCAN™ scantool

NOTE: The DRB III®/StarSCAN™ scantool may be used to reset the Loose Cap message. Select the PCM Reset function on StarSCAN™ (version 6.05_SP1 or higher) or the Clear PCM Batt Disconnect function on DRB III®. Disconnecting and reconnecting the battery will also clear the message. If a gas cap loose message is displayed or DTC P0457 - Evap System - Loose Fuel Cap is set without P0455 - Evap System Large Leak then ensure the gas cap it tight, no further service action is required. Policy: Information Only.

21-015-05 45RFE / 545RFE TRANS - DELAYED ENGAGEMENT DUE TO COOLER RETURN FILTER REPLACEMENT

Date: 09/01/05

Model year(s): 2005-2006

NOTE: This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales code DG4 or DGQ respectively).

Description: This bulletin involves a transmission delayed shift condition that may occur following the replacement of the internal cooler return filter.

Details: The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight. The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.

The customer may not have experienced the delayed shift engagement until after the transmission has been serviced, where the cooler return filter was replaced during the service and/or repair.

The condition is not detrimental to the transmission but may cause concern with the customer.

The above condition may be caused by a suspect cooler return filter a part number of 04799662AB. This “AB” suffix / level filter may allow transmission fluid to drain back out of the torque converter. The drain back condition may occur over a period time when the engine (and transmission) are not running. With less fluid in the torque converter a delay in gear engagement may occur at engine start up while the torque converter fills to its proper fluid level.

All 04799662AB cooler return filters with the “AB” suffix are suspect. The above condition may be corrected by replacing a suspect “AB” filter with a new cooler return filter whose part number is 04799662 (with no suffix or with a suffix that is other than the “AB” level).

NOTE: The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part number is stenciled on the side of the filter case.

NOTE: A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter stud. The threaded adapter stud is used to attach the cooler return filter to the transmission. Inspect the stud and note end without threads. Install the stud end without the threads into the cooler return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.). Once the threaded adapter stud has been installed to the cooler return filter, install the assembled cooler return filter to the transmission and tighten the filter to 14.1 Nm (125 in. lbs.)

21-016-05 RFE Transmission - DELAYED ENGAGEMENT AFTER AN EXTENDED OFF PERIOD

Date: 09/01/05

Model year(s): 2005

NOTE: This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE automatic transmission (sales code DG4 or DGQ respectively).

Description: This bulletin involves verifying the build date of the transmission, and if necessary, replacement of the transmission cooler return filter inside the transmission.

Details: The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight. The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.

The customer may also experience a MIL illumination. Investigation may determine that the MIL is due to one or more of the following Diagnostic Trouble Codes (DTC's):

P0868 - Line Pressure Low. This DTC will be the most frequently occurring DTC for the delayed shift condition.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.
P0944 - Loss Of Hydraulic Pump Prime.

The condition may be caused by a suspect cooler return filter with a part number of 04799662AB. The suspect cooler return filter may allow transmission fluid to drain back out of the torque converter when the engine is not running.

Diagnosis:

1. Turn the ignition to the “OFF” position.

2. Raise the vehicle on a suitable lift.

3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be determined by inspection of the 20 digit transmission identification number (DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side (driver side) of the transmission oil pan flange. The first four (4) digits of the transmission identification number are the transmission build date, in Julian date format. An example of a transmission identification number would be:

101510492P52119684AA. The first three digits ( 101 ) of the identification number equal the day of the year, in this case 101 equals April 11. The fourth digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015 equals April 11, 2005.

4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.

5. If the vehicle has the above condition, and if the transmission Julian build date is on or between the range of dates listed above, perform the Repair Procedure.

NOTE: DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is suspect of causing the above condition. The filter part number is stenciled on the side of the filter case.

Parts Required:

1 P/N 04799662 Filter, Cooler Return
4 P/N 05013457AA Fluid, Automatic Transmission, MS-9602 ATF+4, Quart
1 P/N 05010884AA Mopar ATF-RTV

Repair Procedure:

NOTE: All cooler return filters with the “AB” suffix (04799662AB) are suspect. The above condition may be corrected by replacing a suspect “AB” filter with a new cooler return filter whose part number is 04799662 (with no suffix or with a suffix that is other than the “AB” level).

NOTE: A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter stud. The threaded adapter stud is used to attach the cooler return filter to the transmission. Inspect the stud and note end without threads. Install the stud end without the threads into the cooler return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.). Once the threaded adapter stud has been installed to the cooler return filter, install the assembled cooler return filter to the transmission and tighten the filter to 14.1 Nm (125 in. lbs.)

Use the procedures outlined in TechCONNECT® or the Factory Service Manual (Service Information Tab / 21 - Transmission Transaxle / Automatic - 45RFE 545RFE / Fluid / Standard Procedure / Fluid and Filter Replacement) to replace the cooler return filter.

21-005-06 DRIVELINE NOISE DURING MODERATE TO HIGH THROTTLE ACCELERATION (SRT8)

Date: 03/06/06

Model year(s): 2006 SRT8

Description:FLASH: This bulletin involves selectively erasing and reprogramming the Four Wheel Drive Control Module (FDCM) with new software.

Details:A growling/grinding/low frequency whine sound is heard when accelerating with moderate to high throttle between 45 and 80 kph (30 and 50 mph).

This sound is due to a resonance in the driveline when the transfer case clutch is activated with Electronic Stability Program (ESP) in the full on position. The sound is more prominent when the vehicle is new, and also when first operated in cold weather. The sound may also be present at various throttle positions when ESP is in the partial off position, as the transfer case clutch is activated more often in this mode. The sound generally lessens with transfer case clutch and axle gear set break-in. This sound is characteristic of this vehicle, and does not indicate a defective transfer case or axles. A revision to the FDCM software is now available which eliminates the noise over much of this speed range with the ESP full on.

Diagnosis: If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure (Flash).

21-007-06 RFE TRANSMISSION FILTERS - DELAYED ENGAGEMENT AND RELATED TRANSMISSION DTC'S

Date: 04/07/06

Model year(s): 2005-2006

NOTE: This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE automatic transmission (sales code DG4 or DGQ respectively) having a specific transmission build date code (see the below DIAGNOSIS section for further details).

Description:This bulletin involves verifying the build date of the transmission, and if necessary, the replacement of both the cooler return and sump filters in the transmission.

Details: The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight. The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.

The customer may also experience a MIL illumination. Investigation may determine that the MIL is due to one or more of the following Diagnostic Trouble Codes (DTC's):

P0868 - Line Pressure Low. This DTC will be the most frequently occurring DTC for the delayed shift condition.
P0944 - Loss Of Hydraulic Pump Prime.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.

The delayed engagement and MIL condition (DTC's) may be caused by a suspect transmission cooler return filter with a part number of 04799662AB. A suspect 04799662AB cooler return filter may cause the transmission sump filter to split at its plastic-to-metal crimp. If the transmission sump filter becomes split at the crimp, then one or more of the above DTC's may also occur.

Diagnosis:

1. Turn the ignition to the “OFF” position.

2. Raise the vehicle on a suitable lift.

3. Inspect for the transmission build date (Julian date). The transmission build date can be determined by inspection of the 20 digit transmission identification number (DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side (driver side) of the transmission oil pan flange. The first four (4) digits of the transmission identification number are the transmission build date, in Julian date format. An example of a transmission identification number would be : 101510492P52119684AA. The first three digits ( 101 ) of the identification number equal the day of the year, in this case 101 equals April 11. The fourth digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015 equals April 11, 2005.

4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date build ranges listed below:

a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.

5. If the vehicle has the above condition, and if the transmission Julian build date is on or between the range of dates listed above, perform the Repair Procedure. NOTE: Both the transmission cooler return filter and the transmission sump filter MUST BE replaced at the same time.

Parts Required:

NOTE: DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is suspect of causing the above condition. The cooler return filter part number is stenciled on the side of the filter's metal case.

1 ea. 04799662 Filter, Transmission Cooler Return
1 ea. 05015267AC Kit, Transmission Sump Filter - 4x2 (verify p/n for specific vehicle)
1 ea. 05013470AC Kit, Transmission Sump Filter - 4x4 (verify p/n for specific vehicle)

22-002-04 ERRONEOUS TPM DTC'S DUE TO IOD FUSE NOT BEING INSTALLED

Date: 09/27/04

Model year(s): 2005

Description: This bulletin involves erroneous DTC's that are caused when the vehicle is driven without the IOD fuse installed.

Details: The driver may notice that the Tire Pressure Monitor (TPM) system is not working properly. Whether a premium or base system, the tire pressure monitor warning light in the instrument cluster may be flashing indicating a TPM SYSTEM problem.

On premium TPM systems, the Electronic Vehicle Information Center (EVIC) may display a “SERVICE TIRE PRESS SYSTEM” message. And when stepping through the EVIC to the tire pressure display, all of the tire pressure readings may display as dashes “- -” rather than actual tire pressure values.

Investigation by the technician may find the presence of all four TPM related DTC's:

C1501 - Tire Pressure Sensor 1 (L.F.) Internal
C1502 - Tire Pressure Sensor 2 (R.F.) Internal
C1503 - Tire Pressure Sensor 3 (R.R.) Internal
C1504 - Tire Pressure Sensor 4 (L.R.) Internal

The above condition is most likely caused by driving the vehicle without the IOD fuse installed. If the vehicle is driven at speeds greater than 32 kph (20 mph) for more than approximately ten (10) minutes without the IOD fuse installed, then the TPM system will log the above four DTC's. This scenerio is most likely to occur when the vehicle is driven while in dealer inventory.

Without the IOD fuse installed part of the Wireless Control Module (WCM), the receiver circuit, is not operational (not powered). Though the TPM tire sensors are powered and transmitting correct tire pressure signals, the WCM receiver is not receiving those signals. The portion of the WCM circuitry that is powered, by the ignition on/run feed, sends a CAN message to the Cabin Control Node (CCN) in the instrument cluster indicating that the TPM tire pressure signals are not available. On base and premium TPM systems the CCN will flash the tire pressure monitor warning light, and the powered portion of the WCM will log all four of the above TPM DTC's as faults with the TPM system. On premium TPM systems the CCN will also cause the EVIC to display the “SERVICE TIRE PRESS SYSTEM” message. For the TPM system to operate correctly the IOD fuse must be installed. A scan tool (StarSCAN) will be required to erase the four TPM DTC's.

22-002-05 TIRE PRESSURE MONITOR - SYSTEM INFORMATION

Date: 12/07/05

Model year(s): 2005-2006

Details: If a customer with a 2005 or later DaimlerChrysler vehicle equipped with Tire Pressure Monitoring (TPM) is concerned that the TPM lamp is on continuously, please be sure to inform the customer that the system is in place to warn of a low tire pressure situation, and a system diagnosis may not be required. The customer should be aware of the following:

  • The Tire Pressure Monitoring (TPM) System will warn the driver of a low tire pressure based on the vehicle recommended cold placard pressure (the placard is located on the drivers side B-pillar).
  • The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease - the customer should adjust his tire pressure for this decrease in pressure - please refer the customer to his vehicle owner’s manual for information on how to properly inflate his vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.
  • The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects.
  • The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPM warning lamp to be turned off. The system will automatically update and the TPM warning lamp will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 kph) to receive this information.
FOR EXAMPLE:

A 2006 300 has a recommended cold (parked for more than 3 hours) placard of 30 psi (207 kPa).

If the ambient temperature is 65°F (18°C) and the measured tire pressure is 27 psi (186 kPa) the TPM lamp will be OFF.

IF NOTHING IS DONE TO THE AIR PRESSURE IN THE TIRES and the ambient temperature drops to 20°F (-7°C) while the vehicle is parked, the approximate tire pressure will be 23 psi (157 kPa) and the TPM lamp will be ON.

IF THE VEHICLE IS DRIVEN TO REACH NORMAL OPERATING TEMPERATURE WITHOUT ADJUSTING THE AIR PRESSURE and the ambient temperature stays a 20°F (-7°C), the approximate tire pressure will rise to 27 psi (186 kPa) and the TPM lamp will be ON.

To turn the TPM lamp OFF the tires must be inflated to the vehicle recommended cold placard pressure.

• In order to properly maintain vehicle tire pressure, please refer to the owner’s manual for additional information regarding tire inflation.

NOTE: Tire pressure should always be set based on cold inflation tire pressure (defined as the tire pressure after a vehicle has not been driven for more than 3 hours - and in outside ambient temperature).

• Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.

If a diagnosis of the system is required (for example, the lamp did not extinguish, or the lamp is flashing), please refer to service information available in TechCONNECT for additional information for TPM diagnosis. Please be aware that if the Wireless Control Module (WCM) is replaced, the TPM placard values may need to be reprogrammed. The TPM placard values do NOT need to be updated if the WCM has NOT been replaced, the TPM placard values are properly set in the factory.

23-033-04 CLEANING PROTECTIVE PLASTIC FILM RESIDUE FROM INTERIOR TRIM

Date: 09/02/04

Model year(s): 2005

Description: This bulletin involves the removal of plastic protective film adhesive residue from the interior trim.

Details: For quality purposes a thin plastic film is used to protect various interior trim surfaces. To maximize the protection offered by the plastic film it is recommended that the film not be removed until the vehicle is to be delivered to the new vehicle owner. This means that the plastic film should remain attached to the various interior trim components while the vehicle is in dealer inventory awaiting purchase.

When the protective plastic film is removed a residue may remain on an interior trim component surface. The residue may be removed using Mopar Total Clean cleaner. Testing has shown that Total Clean is effective at removing the film residue without damage to the interior trim components. This may not be true of other aftermarket cleaners. The part numbers for Total Clean are: 04897840AA (16 oz. spray bottle) and 04318020AB (1 gallon bottle).

The protective plastic film is applied to the following interior trim components:

- Center console lid / arm rest
- Lower cowl / kick panel - both front sides
- Sill / scuff plate - both front door openings
- Door arm rest - all four doors
- Map pocket - both front doors

23-050-04 WATER LEAK IN AREA OF A-PILLAR GRAB HANDLE OR OVERHEAD CONSOLE

Date: 12/02/04

Model year(s): 2005

Description: This bulletin involves a review of several possible causes for water leakage in the area of the A-pillar grab handle or overhead console.

Details: A customer may experience a water leak at the A-pillar grab handle (left or right side) or in the area of the overhead console.

Analysis has found the following possible causes for water leakage at these locations:

1. A pinched or collapsed front sunroof drain tube (left or right side) between the headliner and metal roof panel at the outboard sun visor attachment. The pinched front drain tube(s) may cause water to backup in the tube and overflow the sunroof water trough.

2. A body sealer void at top of A-pillar where the front edge of the roof panel is joined tothe A-pillar (body side aperture). A sufficient quantity of the body sealer may not have been applied to the joint.

3. A windshield sealer void at the top of the A-pillar. The front edge of the roof panel causes a “step” in the joint with the A-pillar that if severe enough the windshield sealer may not be able to fully compensate for.

4. A restricted rear sunroof drain tube (left or right side) near the exit end of the drain tube. The rear sunroof drain tube is routed down along the C-pillar. The end of the tube(s) may turn back on itself during installation at the bottom of the C-pillar. Sound deadening foam is applied to the C-pillar cavity once the drain tube is installed. The sound deadener may close off the end of the drain tube.

23-053-04 OPTIMUM ROOF RACK CROSS BAR POSITIONING TO REDUCE AIR TURBULENCE CONCERNS

Date: 12/18/04

Model year(s): 2005

Description: This bulletin involves a discussion regarding the correct installation and positioning of the roof rack cross bars.

A customer may experience an air turbulence or wind whistle-like sound when driving their vehicle. This sound may be caused by a roof rack cross bar that has been installed backwards or a cross bar that has not been positioned correctly to the roof rack side rails.

The optimum position for the roof rack cross bars when not in use is with the rear cross bar at the rearmost position (position #7) of the roof rack side rails, and the front cross bar in the second (#2) position from the front of the roof rack. This position will provide the least amount of air turbulence and wind whistle-like sound. Note that the roof rack side rails may have a unique (arrow, line, etc.) feature used as an alignment mark that is stamped into each rail to indicate the correct position for storing the front and rear cross bars.

If a cross bar is installed backwards, then an air turbulence or a wind whistle-like sound may occur even if the cross bar is properly positioned to the side rails. Cross bars are normally installed by the dealer during pre-delivery or later on by the customer. The leading edge of a correctly installed cross bar has a protruding bead running along the top edge of the bar. Each cross bar has an arrow stamped on its bottom surface that should point toward the front of the vehicle when the cross bar is correctly assembled to the roof rack. Be sure to review the instructions supplied with the roof rack cross bar kit when installing each cross bar (see Figure 2).

Model year(s): 2005

Description: This bulletin applies to vehicles built prior to February 06, 2005

Details: While driving, the customer may experience a rattle-like sound coming from the left or right side of the instrument panel. Closer inspection may reveal that the rattle-like sound is coming from the far left and/or far right air outlet.

This condition may be caused by a loose interference fit between the back of the air outlet and the connecting plastic air duct located behind the air outlet.

Parts required:
Double Back Tape - Dense Closed Cell - Of Length: 300 mm long x 25 mm wide x 3.175 mm thick (12 in. long x 1 in. wide x 0.125 in.or 1/8 in. thick)] - 3M Scotch-Mount Double-Coated Urethane Foam Tape p/n 021200-06452 or equivalent.

Repair procedure:
1. Using a trim stick, carefully remove the right side instrument panel end cap.
2. Locate the connection between the back of the far right side air outlet and the air duct. A foam stuffer will be made out of the double back tape. The foam stuffer will be installed between the bottom side of the air outlet duct and the instrument panel brace. Prep these surfaces to accept the foam stuffer adhesive by making sure the surfaces are clean of any dirt, dust, or oils
(Fig. 1).
3. Cut the 300 mm (12 in.) long double back tape foam into eight 37.5 mm (1.5 inch) long strips. Two foam stuffers will be made using these strips. Each foam stuffer will be made using four of the 37.5 mm (1.5 in.) double back tape strips stuck lengthwise to each other.
4. Build a foam stuffer. Adhere (stick) the long wide sides of the four strips to each other. When done the foam stuffer created should be 37.5 mm long x 25 mm wide x 12.7 mm thick (1.5 in. x 1.0 in. x 0.5 in.). Make a second foam stuffer of equal size using the remaining four unused strips.
5. Remove the adhesive protective backing from both ends/sides of a foam stuffer.
6. Install the foam stuffer between the bottom of the air outlet duct and the instrument panel brace. Verify good adhesion of the stuffer.
7. Carefully install the right side instrument panel end cap.
8. Perform the same repair as above to the far left side IP air outlet and duct.

Date: 4/19/05

Model year(s): 2005

Description: This bulletin applies to vehicles built prior to May 01, 2005. This bulletin involves inspecting and correcting several possible door glass issues.

Details: The customer may experience one or more of the following door glass conditions:

  • Moan-like sound when the door glass is in operation. This condition occurs when the glass is moved downward. This condition may be due to the door inner belt line molding - secondary (lower) seal. The secondary seal may turn under as the glass moves downward.
  • Door glass sticks, track poorly, pivots, or falls down inside door. This condition may be due to the glass not being installed correctly to the window regulator clamps.
  • Door glass binds or tracks poorly. This condition may be due to the glass not being properly adjusted to the door or loose window hardware.
Diagnosis: If one or more of the above conditions are present, perform the Repair Procedure to the specific door that has the condition(s).

Parts Required:
The plastic retainers used to attach the door trim panel to the inner door panel must be replaced each time the door trim panel is removed.

P/N 06507686AA Retainer, Door Trim Panel (8 required for each front door / 7 required for each rear door)


Repair Procedure:

1. Disconnect and isolate the negative battery cable from the battery.
2. Remove the door trim panel
(Fig. 1).
3. Remove the door inner belt line molding from the door flange.

  • Remove the secondary (lower) seal from the main body of the inner belt line molding. This can be accomplished by making a “starter” cut at one end of the secondary seal. Carefully pull on the loose end of the secondary seal to remove it from the main body of the inner belt line molding (Fig. 2).
  • Install the door inner belt line molding to the door flange.

25 Emissions

25-001-04 EVAPORATIVE SYSTEMS SERVICE

Date: 11/22/04

Model year(s): 2005

Description: The Evaporative Emissions Systems on today's vehicles are comprised of sophisticated components, all of which must be operational for the system to perform properly. To remain operational all components must be properly maintained and serviced as describe in the appropriate service information available on TechCONNECT.

All worn, damaged, or inoperative evaporative emissions components must be replaced with new, unused components available from DaimlerChrysler.

In addition all evaporative emissions hoses both pre-formed and straight must be replaced in their entirety. Under no circumstances should a worn or damaged hose be repaired. Any attempt to repair a worn or damaged hose may result in a future repeat failure of the same hose, and the customer may experience a repeat condition. Hoses must be replaced with new assemblies when available or approved bulk hose when the assemblies are not available.

The approved service procedure, using new MOPAR service components, is the only way to ensure that a repair of the evaporative emission system will be permanent. This is very important to ensure that the evaporative emission system functions properly for the useful life of the vehicle.
