SUBJECT:

FLASH: Engine Start and Driveability At Altitude Or Brake Switch DTC P0504

 

OVERVIEW:

This bulletin involves selectively erasing and reprogramming the Engine Control Module (ECM) with new software.

 

MODELS:

2005 – 2006 (KJ) Liberty
** 2006 (KJ) Cherokee **

 

NOTE: This bulletin applies to vehicles equipped with a 2.8L engine (sales code ENR) built prior to November 21, 2005 (MDH 1121XX).

 

SYMPTOM/CONDITION:

The vehicle operator may experience one or more of the following:

  1. At an altitude of 5,000 ft. or higher, a cold engine start and/or warm engine restart that is followed by a slow to idle up condition (domestic market vehicles only).
  2. At an altitude of 5,000 ft. or higher, an Idle and/or off-idle engine shake during engine warm-up condition (domestic market vehicles only).
  3. A MIL Illumination due to DTC P0504 Brake Switch Signal Circuits Plausibility With Redundant Contact (domestic and international market vehicles).

 

DIAGNOSIS:

Using a Scan Tool (DRBIII or StarSCAN) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine 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.

If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure.

NOTE: There are three separate Repair Procedures. Repair Procedure A is used for domestic 2005 KJ vehicles. Repair Procedures B or C are used for 2006 KJ vehicles (international or domestic market).

NOTE: There are two methods to download flash files to StarSCAN. The first (preferred) method is to download the flash files to the StarSCAN from the internet. The second method is to download the flash files from the StarSCAN Software Update CD.

REPAIR PROCEDURE A: FOR DOMESTIC VEHICLES USING DRBIII AND DOWNLOADING THE FLASH FILE FROM DealerCONNECT:

NOTE: Whenever a module is reprogrammed, the software in the DRBIII; must be programmed with the latest revision level available.

NOTE: If this flash process is interrupted/aborted, the flash process should be restarted and then follow the directions on the DRBIII.

  1. Before beginning the flash procedure, remove any old flash files from the DRBIII memory. To clear the memory from the MAIN MENU:
    1. Simultaneously press the “MORE” and “YES” keys.
    2. A screen will appear requesting a “COLD BOOT”.
    3. Follow the on screen instructions by selecting the “F4” key.
    4. When the DRBIII® reboots to the MAIN MENU, proceed to Step #2
  2. With the ignition switch in the “RUN” position, determine the original part number of the ECM currently in the vehicle. Using the DRBIII select: a. “DRBIII Standalone”.
    1. “1998 – 2005 Diagnostics”.
    2. “All (Except Below)”.
    3. Engine”.
    4. “Module Display”.
    5. Record the “ECM part #” on the repair order for later reference.
  3. Connect the DRBIII to TechCONNECT. Open TechTOOLS and verify that the “DRBIII Status: Connected” message is in the upper right corner of the TechTOOLS screen.
  4. Enter the “ECM part #” recorded in Step #2 in the “Parts Criteria” area and select “Show Updates”. TechTOOLS will populate the appropriate flash file.
  5. Select the flash file.
  6. Select the “DRBIII” radio button which is next to the “Download/Update” button.
  7. Select the “Download/Update” button.
  8. Monitor the “Flash Download/Update Progress” window on the TechCONNECT and follow the instructions on TechCONNECT. When the download process is complete, proceed to Step #9.
  9. Disconnect the DRBIII from TechCONNECT.
  10. Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.
  11. Connect the DRBIII to the vehicle.
  12. Download the ECM flash file from the DRBIII to the vehicle. Using the DRBIII select:
    1. “Vehicle Flash”.
    2. Follow the directions on the DRBIII screen. When the flash process is complete,proceed to the next step.
  13. Reset the “Pinion Factor” as necessary.
  14. Perform the transmission Quick Learn Procedure as necessary.
  15. Update the Sentry Key Immobilizer Module (SKIM) or Sentry Key Remote EntryModule (SKREEM), Secret Key data if necessary.

NOTE: Due to the ECM programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKIM, etc.) within the vehicle, if so equipped. Some DTC’s may cause the MIL to illuminate. Check all modules using “Module Scan”, record the DTC’s, and erase these DTC’s prior to returning the vehicle to the customer. Erase any DTC’s in the PCM only after all other modules have had their DTC’s erased.

NOTE: The following step is required by law when reprogramming a ECM and/or TCM.

  1. Type the necessary information on the “Authorized Modification Label” p/n04275086AB and attach near the VECI label ( 1).

Additional Information and Known Issues / Concerns:

If you are reprogramming the 5.9L diesel engine controller on the 1996-2008 Dodge RAM vehicle, it is necessary to also reprogram the VIN after the ECU has been flashed.  To write the VIN to the ECU, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.

  • 1996-2009 ALL PCMs

If you are REPLACING a PCM or ECM and the vehicle is equipped with a theft deterrent system (Sentry Key), it must be initialized to properly function with the Anti Theft module. You also need to reprogram the VIN when replacing a PCM or ECM.  To write the VIN to the ECU and initialize the PCM to work with the theft deterrent system, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.


FCA US LLC Scan Tool Lease Options:

  • For 2009 model year vehicles and prior, it may be necessary to use either a DRBIII or a StarSCAN to perform function required after ECU replacement.  To lease the DRBIII call 1-586-532-8400 or click here.
  • Beginning with 2010 MY, function required to replace an ECU will be supported via the J2534 application.
