Information

NOTE:
When ECM reprogramming is required to repair a vehicle, a Technical Service Bulletin will be issued.

ECM reprogramming involves two general steps:

^ Download (transfer) data from ASIST into CONSULT-II.

^ Download new data from CONSULT-II into the vehicle (Reprogram ECM).

Before beginning the reprogramming procedure, use CONSULT-II and the Diagnostic Card (red/white one) to retrieve any stored DTC(s). Additional repairs may be necessary if there are DTC(s) not associated with a Reprogramming bulletin. Refer to the appropriate TSB or Service Manual.
