Overview:
This Bulletin provides guidelines, to minimize flash reprogramming problems, and information
on recovery procedures for failed flash attempts.

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 Modules
(BCMs) do not require labels.

FLASH REPROGRAMMING SEQUENCE OF EVENTS

The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially
interfere with the process. This document seeks to provide information to minimize problems
associated with vehicle control module flash reprogramming. The description that follows is for
most PCMs and some TCMs. Other modules use different initiation procedures.

The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII. Once the flash reprogramming update is loaded into
the DRBIII, and before the flash reprogramming begins, the DRBIII verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is
done using part number supersedence. This verification occurs only if an update is required,
available (on the TechCONNECT Client or ISIS) and has been selected for programming.

SOFTWARE VERSIONS MUST BE CURRENT

Before attempting a flash reprogramming session using the TechCONNECT Client, make sure
you have the most current DRBIII software installed.

To verify whether your DRBIII software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII Available Version, DRBIII Current Version.

Often, because of multiple DRBIIIs in the shop, not all will get updated on a timely manner.
The installed DRBIII software version can generally be found at the bottom center of most
screens. Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII Main
Menu and comparing it to what is available from a current TechCONNECT Client as described
above.

If the TechCONNECT Client is current and the DRBIII is not, it may be due to the fact that
the TechCONNECT Client does not force DRBIII updates for 9minor9 revisions. Changes and
new support are added to the Vehicle Flash application on 9minor9 revisions on a regular
basis. This is why your TechCONNECT Client and DRBIII must have the LATEST software
revisions installed.

DO NOT PASS on the option for updating to a "minor" revision!

Major updates require the DRBIII to be updated prior to allowing any flash programming.

Note from Dave F:  When the vehicle is "flashed" (new software loaded into the PCM or other locations on board the vehicle) the update procedure may not complete properly and/or the diagnostic equipment may "lock up" during the process.  The TSB lists several possible problems and a process to reinitialize the flash procedure.  Since you probably do not have a DRB III or the CD software or the cables, the very long procedure is not posted. If you need the complete bulletin, see your dealer for a copy. If you can't find a dealer that will provide a copy, contact me; I can email send you a pdf version.
