Using a Scan Tool (DRBIII) with TechCONNECT or the appropriate Diagnostic Procedures Manual, 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.
|1||04275086AB||Label, Authorized Modification|
Special Tools/Equipment Required:
|CH2002||General Purpose Interface Bus Cable Assembly|
|CH6000A||Scan Tool (DRBIII)|
|CH7000A||J1962 Cable with red DRBIII connector|
NOTE: An updated J1962 cable has been released. This cable has a red colored connector at the DRBIII connection. Use this cable whenever a flash is being performed.
NOTE: Whenever a controller is programmed, the software in the DRBIII 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.
Most owners do not have access to the software and equipment required to program the ECM. To see the specific instructions, download the pdf version.
NOTE: Due to the PCM 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.
Type the necessary information on the “Authorized Modification Label” p/n 04275086AB and attach near the VECI label (Figure 1).
