PARKING LAMP CIRCUIT
Description
INFOID:0000000006179033
The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs
from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows through
fuse 37, located in the IPDM E/R. Power then flows to the front and rear combination lamps.
