EQUIPMENT REQUIRED
REPAIR PROCEDURE:
NOTE:
WHENEVER A PCM/TCM IS REPLACED OR REPROGRAMMED, THE SOFTWARE IN THE CONTROLLER AND THE DRBIII(R) MUST BE VERIFIED AS HAVING THE LATEST REVISION LEVEL.
1. Connect a battery charger and set as close to 14 volts charge as possible.
2. Flash the PCM using the MDS2 (Mopar Diagnostic System) and DRBIII(R).
NOTE:
DUE TO THE PCM REPROGRAMMING 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. ALL DTC'S RELATE TO A LOSS OF COMMUNICATIONS WITH THE MODULE THAT IS BEING REPROGRAMMED. CHECK ALL MODULES, RECORD THE FAULTS, AND ERASE THESE FAULTS PRIOR TO RETURNING THE VEHICLE TO THE CUSTOMER. ERASE ANY FAULTS IN THE PCM ONLY AFTER ALL OTHER MODULES HAVE HAD THEIR FAULTS ERASED.
NOTE:
THE FOLLOWING STEPS ARE REQUIRED BY LAW.
3. Type the necessary information on the "Authorized Software Update Label" p/n 04669020 (Fig. 1). Attach the label to the PCM and/or TCM as necessary and cover the label(s) with the clear plastic overlay.
4. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label (Fig. 2)
