POWERTRAIN MODULES - ENGINE AND TRANSMISSION
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions
that are somewhat unique to each type will have comments. Prior to reprogramming a
PCM, retrieve the module information and module type using your DRBIII®. PCM
information is used by many modules. Be sure to check DTC's before and after
performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of
communication" with the other modules during the reprogramming session.
SBEC
Types:
• SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE: During recovery, if the DRBIII® is not seeing the key off, you may need to
remove power (B+) to PCM by removing fuse(s) or disconnecting the PCM.
When DRBIII® states to turn key ON, reconnect fuse or harness connection.
Abort Recovery Specifics:
• Follow instructions on the DRBIII® for the module type. See table above.
• Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not
correctly identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII®: "Can not
read Part Number. Did not see Key On or PCM/TCM Controller may not be
flashable". When this occurs restart the flash session and when prompted to turn the
ignition key to the LOCKED position, pull the fuse(s) that supply battery power to the
module instead. When prompted to turn the key to the RUN position, replace the battery
supply fuse(s) instead.
JTEC
Types:
• JTEC, JTEC +
NOTE: Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE: 1999 WJ JTEC with Speed Proportional Steering module. Disconnect before
and reconnect after the PCM flash reprogramming session. Also see
Transmission.
Abort Recovery Specifics:
• Follow DRBIII® prompts carefully.
NGC
Types:
• NGC 1, NGC 2, and NGC 3
