TURN SIGNAL LAMP CIRCUIT
TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000009463597
The BCM monitors inputs from the combination 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 haz-
ard warning operation. The BCM sends a turn signal indicator request to the combination 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:0000000009463598
