INFOID:0000000001523237

System Description

INFOID:0000000001523238

The BCM (Body Control Module) controls front fog lamp operation based on input from the lighting switch
(combination switch). The BCM requests (via CAN communication lines) the IPDM E/R (Intelligent Power Dis-
tribution Module Engine Room) to activate the integrated front fog lamp relay and requests the combination
meter to illuminate the front fog lamp light.

REAR FOG LAMP

System Diagram

INFOID:0000000001527666

System Description

INFOID:0000000001527667

The BCM (Body Control Module) controls rear fog lamp operation based on input from the lighting switch
(combination switch). When the lighting switch is in the 1st or 2nd position or auto position and the rear fog
lamp switch is ON, the BCM outputs battery voltage to the rear fog lamps. The BCM sends a request signal to
the combination meter via CAN communication lines to illuminate the rear fog lamp indicator.
