- Turn ignition on. Apply parking brake. Check that parking brake warning light illuminates. If light illuminates, go to next step. If light did not illuminate, repair wire harness or bulb.
- Turn ignition off. Remove main power relay. Check for continuity between relay terminal No. 30 and 87a. If continuity is present, go to next step. If continuity is not present, replace main relay. Check light illumination.
- Check for continuity between main power relay connector pin No. 87a on harness side and ground. If continuity is present, go to next step. If continuity is not present, repair open circuit. Check light illumination.
- Check for continuity between main power relay connector pin No. 30 and Blue/Green wire. If continuity is present, go to next step. If continuity is not present, repair open circuit.
- Check for continuity between 12-pin instrument cluster connector pin No. 7 and diode in Brown/Red wire. If continuity is present, go to next step. If continuity is not present, repair open circuit.
- Check for continuity between 12-pin instrument cluster connector pins No. 6 and 7 on harness side. If continuity is present, replace diode. If continuity is not present, go to next step.
- Remove "ANTI-LOCK" warning light bulb. Check continuity of bulb. If continuity is present, replace instrument cluster printed circuit. If continuity is not present, replace bulb.
