OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Body Control Module (BCM) with new software.
MODELS:

NOTE:
This bulletin applies to vehicles built prior to October 13, 2004 (MDH 1013XX).
SYMPTOM/CONDITION:
The customer may notice that the interior dome lamp may have turned on and can not be turned off as intended. In this condition, the dome lamp may be turned off if the negative battery cable is disconnected.
DIAGNOSIS:
Using a Scan Tool (DRBIII(R)) with TechCONNECT or the appropriate Diagnostic Procedures Manual, 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.
If the customer describes or experiences the Symptom/Condition, perform the Repair Procedure.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE:
NOTE:
Whenever a controller is programmed, the software in the DRBIII(R); must be programmed with the latest revision level available.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the directions on the DRBIII(R).
1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from the DRBIII(R) memory. To clear the memory from the MAIN MENU power up the DRBIII� and then:
a. Simultaneously press the "MORE" and "YES" keys.
b. A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRBIII(R) 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 BCM currently in the vehicle. Using the DRBIII(R) select:
a. "DRBIII(R) Standalone".
b. "1998 - 2004 Diagnostics".
c. "All (Except Below)".
d. "Body Interior".
e. "Body Computer".
f. "Module Display".
g. Record the "BCM part # " on the repair order for later reference.
3. Connect the DRBIII(R) to TechCONNECT. Open TechTOOLS and verify that the "DRBIII(R) Status: Connected" message is in the upper right corner of the TechTOOLS screen.
4. Enter the "BCM part # " recorded in Step # 2 in the "Parts Criteria" area and select "Show Updates". TechTOOLS will populate the appropriate calibration.
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 flash process is complete, proceed to Step # 9.
9. Disconnect the DRBIII(R) 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(R) to the vehicle.
12. Download the flash from the DRBIII(R) to the vehicle. Using the DRBIII(R) select:
a. "Vehicle Flash".
b. Follow the directions on the DRBIII(R) screen.
NOTE:
Due to the BCM programming procedure, a DTC may be set in other modules (TCM, PCM, 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.
