NOTE: You need ASIST 8.0 or higher for this procedure.

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.
