Overview:
This bulletin involves flash reprogramming each Power Sliding Door (PSD) and/or Power Liftgate (PLG) module(s) and resetting obstacle detection values.

Symptom/Condition:
When opening the PSD and/or PLG using the Remote Keyless Entry (RKE), overhead console switch, or B pillar switch, the PSD and/or PLG may "pop off" but not power open. The power close feature will operate as designed.

Diagnosis:
If the customer describes the above Symptom/Condition and the Diagnostic Trouble Code (DTC) is INCOMPLETE POWER OPEN - EXCESSIVE HALL EFFECT SIGNAL (active or stored), flash each PSD and/or PLG module(s) the vehicle is equipped with and reset obstacle detection values in each module flashed.

NOTE :DTC "INCOMPLETE LATCH RELEASE - SECTOR GEAR RETURN FAILURE" (ACTIVE OR STORED) MAY OR MAY NOT BE PRESENT ALSO.

Parts Required:
Not Available

Special Tools/Equipment Required:

NOTE: THE TechCONNECT/MDS2 AND DRBIII ARE REQUIRED TO PERFORM PART OF THIS REPAIR. THE TechCONNECT/MDS2 SYSTEM MUST BE OPERATING WITH CIS CD2126 OR HIGHER.

Repair Procedure:  NOTE :THE DRIVER SIDE FRONT DOOR MUST BE OPEN AND THE IGNITION KEY TURNED OFF AND REMOVED FROM THE IGNITION LOCK CYLINDER WHEN THIS FLASH IS PERFORMED.

1. Connect a battery charger and set as close to 14 volts charge as possible.

2. Log onto the TechCONNECT/MDS2 System.

3. Connect the TechCONNECT/MDS2 and DRBIII(R) to the vehicle and switch the ignition to "ON".

NOTE :AUTO CONNECTION WILL OCCUR ONCE THE DRBIII(R), TechCONNECT/MDS2 AND VEHICLE ESTABLISH COMMUNICATION. THE "CANNOT READ VIN FROM DRBIII(R) MESSAGE (ON THE TechCONNECT/MDS2) WILL BE REPLACED BY THE VEHICLE VIN. PRESS THE "OK" BUTTON ON THE TechCONNECT/MDS2 TO REQUEST A TechCONNECTIMDS2 SESSION FOR THE VEHICLE VIN INDICATED. PRESS THE "OK" BUTTON WHEN ASKED TO BEGIN SESSION.

4. Push the FLASH tab on the TechCONNECT/MDS2.

5. Select READ PART NUMBERS FROM VEHICLE and click SHOW UPDATES on the TechCONNECT/MDS2.

NOTE :A MESSAGE MAY APPEAR (AFTER STEP 3 OR 4) THAT INDICATES NO UPDATES ARE AVAILABLE. IF THIS OCCURS, MAKE SURE YOUR DIAGNOSTIC EQUIPMENT IS OPERATING AT THE LATEST SOFTWARE LEVEL AS LISTED EARLIER IN THIS BULLETIN. IF THE LATEST SOFTWARE IS INSTALLED, AND NO UPDATES ARE AVAILABLE, ANOTHER VEHICLE CONDITION EXISTS THAT WILL REQUIRE FURTHER INVESTIGATION.

6. Select the new software part number with the light pen and click UPDATE CONTROLLER SOFTWARE.

7. The TechCONNECT/MDS2 and DRBIII(R) will prompt for any operator action needed during the remainder of the reprogramming process.

NOTE :INSTRUCTIONS ON THE DRBIII(R) SCREEN WILL ASK FOR THE IGNITION KEY TO BE TURNED TO THE "LOCK" POSITION, THIS MUST BE DONE WITHIN 15 SECONDS. SHORTLY AFTER THE IGNITION KEY IS PLACED IN THE "LOCK" POSITION, REPROGRAMMING WILL BEGIN. THE IGNITION KEY MUST REMAIN IN THE "LOCK" POSITION UNTIL THE DRBIII(R) SCREEN ASKS FOR THE KEY TO BE TURNED TO THE "ON" POSITION.

8. If any additional PSD and/or PLG module(s) require flash update, repeat steps 5 through 7 for each additional PSD and/or PLG module(s) the vehicle is equipped with.

NOTE : WHEN FLASHING BOTH PSD MODULES, CYCLE THE KEY AND REBOOT THE DRBIII(R) (BY UNPLUGGING THE CH7000 CABLE) (DO NOT COLD BOOT!) BEFORE FLASHING THE SECOND DOOR MODULE.

9. Cycle each PSD and/or PLG open/close three times. This will reset the obstacle detection values in each module.

10. Using the DRBIII(R), clear any DTC's which were set during the flash process.

11. If the flash procedure does not correct the PSD and/or PLG failure to move out of the primary latching position, replace the latch on that door.
