CIRCUIT OPERATION
Battery feed for the Body Control Module (BCM) is supplied on two circuits.
Circuit M1 supplied battery voltage to the BCM at all times. This is the Ignition-Off Draw circuit, and is protected by a 10 Amp fuse located in cavity 10 of the Power Distribution Center (PDC). This circuit is HOT at all times. This fuse is removed during vehicle shipping to prevent excessive battery draw.
The F11 circuit also supplies voltage to the BCM. This circuit is HOT when the ignition switch is in the ON, RUN, and START positions. This circuit is protected by a 10 Amp fuse located in cavity 2 of the junction block.
