YES: Repair the harnesses or connectors.
NO: GO TO 3.
- CHECK BCM INPUT SIGNAL
- Connect BCM and combination switch connectors.
- Turn ON any switch in the system that is malfunction.
- Check voltage between BCM harness connector and the ground.
System Terminals Voltage (Approx.) (+) (-) BCM Ground Connector Terminal INPUT 1 M65 6 Refer to "REFERENCE VALUE ". INPUT 2 5 INPUT 3 4 INPUT 4 3 INPUT 5 2 Is the measurement value normal?
Yes: Replace BCM. Refer to "EXPLODED VIEW ".
No: GO TO 4.
- CHECK COMBINATION SWITCH
Check combination switch. Refer to "DESCRIPTION ".
Is the check result normal?
YES: Replace BCM. Refer to "EXPLODED VIEW ".
NO: Replace the combination switch (applicable parts).
