Principles of Operation: Notes

WARNING: This page is about a different variant/trim than selected.

NOTE: Replacement of the Passive Anti-Theft System (PATS) transceiver does not require the PATS keys to be programmed into the Instrument Cluster (IC) again.

NOTE: Make sure any aftermarket remote start systems have been removed from the vehicle before any PATS-related no-start concerns are investigated.

NOTE: A minimum of 2 PATS keys must be programmed into the IC before the vehicle starts.

NOTE: When using the IDS, the IC and the TCM parameters are reset at the same time.

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
