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 lamps (lh) on
Rh : turn signal lamps (rh) on
Off : the turn signal lamps off
Does the turn signal lamp blink? Yes >> turn signal lamp circuit is normal.
No >> refer to exl-99, "diagnosis procedure".
Diagnosis procedure
Regarding wiring diagram information, refer to exl-58, "wiring diagram".
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.
Is the bulb ok? Yes >> go to 2.
No >> replace the bulb.
2.Check turn signal lamp output voltage
Is the inspection result normal? Yes >> go to 5.
No >> go to 3.
3.Check turn signal lamp circuit for open
Is the inspection results normal? YES >> GO TO 4.
NO >> Repair or replace the harness or connectors.
4.Check turn signal lamp short circuit
Are the inspection results normal? YES >> Replace BCM. Refer to BCS-73, "Removal and Installation" (with Intelligent Key system) or BCS- 126, "Removal and Installation" (without Intelligent Key system).
NO >> Repair or replace the harness or connectors.
5.Check turn signal lamp ground circuit
Are the inspection results normal? YES >> Replace the malfunctioning lamp.
NO >> Repair or replace the harness or connectors.
