FRONT FOG LAMP
System DiagramINFOID:0000000001523237
System DescriptionINFOID: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.
