Component Description: BCM

The BCM controls the run/start relays and sets the vehicle ignition mode based on inputs and communicates the ignition mode to other modules over the CAN. If a fault is detected in the ignition switch system, Diagnostic Trouble Codes (DTCs) are set in the BCM.

The BCM requires at least 2 keys to be programmed, and the PMI and parameter reset procedures carried out when replaced. Additionally, if equipped with a steering column lock module, the BCM to Electronic Steering Column Lock (ESCL) configuration must be carried out.
