Circuit Description

The body control module (BCM) monitors the Ignition 0, Ignition 1, Crank and Accessory circuits from the ignition switch. The BCM uses the voltage state (B+ or 0) and the sequence of state changes to determine the power mode called for by the ignition switch. Refer to the table in Body Control System Description and Operation .
