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.
Component Function CheckINFOID:0000000001523266
