FRONT FOG LAMP CIRCUIT
DescriptionINFOID:0000000001523265
The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on
inputs from the BCM via the CAN communication lines. When the front fog lamp relay is energized, power
flows from the front fog lamp relay to fuse 56 in the IPDM E/R and on to the front fog lamps.

REAR FOG LAMP CIRCUIT
DescriptionINFOID:0000000001527571
The BCM (Body Control Module) controls power to the rear fog lamps based on inputs from the lighting switch
(combination switch). The BCM sends a request (via CAN communication lines) to the combination meter to
turn the rear fog lamp indicator light ON.
