Test S: Red Brake Warning Light Inoperative

NOTE: For additional brake warning light information and testing, see appropriate DISC & DRUM article in BRAKES.
  1. 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
  2. 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.
  3. 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.
  4. 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.
  5. 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.
