Test S: Red Brake Warning Light Inoperative
NOTE:
For additional brake warning light information and testing, see appropriate DISC & DRUM article in BRAKES.
- Turn ignition on. Set parking brake. If Red BRAKE warning light illuminates, release parking brake and go to next step. If light does not illuminate, go to step 4
- Turn ignition off. Disconnect brake fluid level switch connector. Connect a 10-amp fused jumper wire between brake fluid level switch connector Dark Green/Yellow wire terminal and ground. If Red BRAKE warning light illuminates diagnose anti-lock brake system. See appropriate ANTI-LOCK article in BRAKES.
- Turn ignition off. Disconnect instrument cluster connector C-216. Measure resistance between instrument cluster connector C-216 terminal No. 5 (Violet/White wire) and brake fluid level switch connector Violet/White wire terminal. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair Violet/White wire and retest system.
- Turn ignition off. Disconnect parking brake switch connector. Connect a 10-amp fused jumper wire between parking brake switch connector Light Green/Red wire terminal and ground. Turn ignition on. If Red BRAKE warning light illuminates replace parking brake switch. If Red BRAKE warning light does not illuminate, go to next step.
- Turn ignition off. Disconnect instrument cluster connector C-216. Measure resistance between terminal No. 6 (Violet/White wire) of instrument cluster harness connector and parking brake switch connector Light Green/Red wire terminal. If resistance is less than 5 ohms, replace instrument cluster printed circuit. If resistance is greater than 5 ohms, repair circuit between instrument cluster connector and parking brake switch connector.
