Step 2. With the ignition switch in the “RUN” position, determine the original part number of the PCM currently in the vehicle. If the original PCM number begins with 05 no change to the flash selection process is required. This new number from the chart should then be entered into the Tech tools application as the orginal part number. NOTE: If your vehicle is a 2002 LH and the original PCM part number begins with 04,the technician should use the 2002 LH Part Number Reference chart above to determine the corresponding “NEW” part number. When the DRB III® reboots to the MAIN MENU, proceed to Step 2.Follow the on screen instructions by selecting the “F4” key.A screen will appear requesting a “COLD BOOT”.Simultaneously press the “MORE” and “YES” keys.To clear the memory from the MAIN MENU power up the DRBIII and then: Step 1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from the DRBIII memory. NOTE: If this flash process is interrupted/aborted, the flash should be restarted and then follow the directions on the DRBIII emulator. Then turn the KEY to the RUN position and Press Page Forward to begin the PCM flash session.
Before pressing Page Forward to begin the flash of the PCM Turn the Key to the OFF position and disconnect the BCM.
The BCM will need to be disconnected after the module ID portion of the flash is complete. When flashing a 2002 – 2004 LH vehicle the BCM may need to be disconnected if experiencing failures during the flash of the transmission portion of the PCM. The module can only be reprogrammed to a more recent version of that calibration. Once a calibration is selected and programmed, the controller cannot be reprogrammed to a different calibration.
A Diagnostic Trouble Code (DTC) will be set – “not programmed”.ĬAUTION: Extreme care must be taken when programming a calibration into a generic PCM. The PCM will not operate the engine until it is programmed. Replacement of future PCMs will require programming utilizing the DRBIII and TechCONNECT. New modules will no longer be pre-programmed when received from Mopar®. Mopar® is currently phasing out pre-programmed PCMs for the vehicles listed. I have flash DVD for the wiTech VCI Pod DRB III, hopefully I will get it and can then do programming on a “swap” system.
