Diagnosis Procedure
- CHECK OUTPUT 1 - 5 CIRCUIT FOR OPEN
- Turn the ignition switch OFF.
- Disconnect BCM and combination switch connectors.
- Check continuity between BCM harness connector and combination switch harness connector.

YES: GO TO 2.
NO: Repair the harnesses or connectors.
- CHECK OUTPUT 1 - 5 CIRCUIT FOR SHORT
Check for continuity between BCM harness connector and the ground.

YES: Repair the harnesses or connectors.
NO: GO TO 3.
- CHECK BCM OUTPUT VOLTAGE
- Connect BCM connector.
- Check voltage between BCM harness connector and the ground.
System Terminals Voltage (Approx.) (+) (-) BCM Ground Connector Terminal OUTPUT 1 M65 36 Refer to "REFERENCE VALUE ". OUTPUT 2 35 OUTPUT 3 34 OUTPUT 4 33 OUTPUT 5 32 Is the measurement value normal?
YES: GO TO 4.
NO: Replace BCM. Refer to "EXPLODED VIEW ".
- 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).
