Description
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 hazard 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 Check
1.CHECK TURN SIGNAL LAMP
CONSULT
LH : Turn signal lamp LH blinking
RH : Turn signal lamp RH blinking
OFF : The turn signal lamp OFF
Diagnosis Procedure
1.CHECK TURN SIGNAL LAMP BULB
Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.
2.CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE
3.CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN
4.CHECK TURN SIGNAL LAMP SHORT CIRCUIT
Check continuity between the BCM harness connector and ground.
5.CHECK TURN SIGNAL LAMP GROUND CIRCUIT
