DISCUSSION:
NOTE: Many of the reasons a flash reprogramming procedure may not complete are
documented in this service bulletin, but if you are constantly having issues
performing the flash reprogramming procedure using a specific DRBIII®, it is
suggested you send the DRBIII® in question to SPX/Miller Special Tools for
service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic
equipment may lock up or become disconnected during the procedure. Flash
Reprogramming is a "CRITICAL PROCESS"; an error may result in a no-start/failed
control module. Most modules, encountering an interruption or failure while
reprogramming, are recoverable; a recoverable module is not covered under the
provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the
flash procedure, and miscellaneous information that will help prevent needless
replacement of control modules.
GENERAL:
Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming
update. Often other parts may need to be serviced, replaced, or tested, prior to flash
reprogramming, and ARE REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM)
there are other legal requirements with labeling issues that are included in those service
bulletins.
Other non-emission related modules, such as instrument clusters and Body Control
