Standard Procedure - Pcm/Skim Programming: Notes
WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
There are two procedures for transfering the secret key to the SKIM:
- When ONLY the SKIM module is replaced, the secret key is transfered from the PCM (NGC- gasoline engine) or ECM (Cummins - diesel engine) to the SKIM. The ORGINAL KEYS may then be programmed to the SKIM.
- When ONLY the PCM/ECM is replaced, then the secret key is transfered from the SKIM to the PCM/ECM. The ORGINAL KEYS may be used.
- When BOTH the SKIM and the PCM/ECM are replaced the secret key is transferred from the SKIM to the PCM/ECM, and NEW KEYS must be programmed.
