HEADLAMP (HI) CIRCUIT
DescriptionINFOID:0000000012432804
The IPDM E/R (intelligent power distribution modul e engine room) controls the headlamp high relay based on
inputs from the BCM via the CAN communication lines. When the headlamp high relay is energized, power
flows through fuses 34 and 35, located in the IPDM E/R. Power then flows to the front combination lamp LH
and RH high beams.

TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000012432813
The BCM monitors inputs from the combination switch (lighting and turn signal switch) to determine when to
activate the turn signals. The BCM outputs voltage direction to the left and right turn signals during turn signal
operation or both during hazard warning operation. The BCM sends a turn signal indicator request to the com-
bination meter via the CAN communication lines.
The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
Turn signal lamp blinks at normal speed when using the hazard warning lamp.
Component Function CheckINFOID:0000000012432814
