  1. If hydraulic brake system diagnostic system check has been performed, go to next step. If hydraulic brake system diagnostic system check has not been performed, see HYDRAULIC BRAKE SYSTEM DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  2. Turn OFF the ignition. Turn ON the ignition, with the engine OFF. Observe the red BRAKE indicator. Does the Red BRAKE indicator illuminate briefly during the displays test? If so, go to next step. If not, go to step  11.
  3. Apply the parking brake. Does the Red BRAKE indicator illuminate? If so, go to next step. If not, go to step  5.
  4. Turn OFF the ignition. Release the parking brake. Disconnect the brake fluid level switch, located on side of master cylinder reservoir. Connect a 3-amp fused jumper wire between the signal circuit of the brake fluid level switch and the ground circuit of the brake fluid level switch. Turn ON the ignition, with the engine OFF. Does the Red BRAKE indicator illuminate? If so, go to step  10. If not, go to step  7.
  5. Turn OFF the ignition. Disconnect the parking brake switch. See PARKING BRAKE SWITCH  under REMOVAL & INSTALLATION as necessary to access parking brake switch electrical connector. Connect a 3-amp fused jumper wire between the signal circuit of the parking brake switch and a good ground. Turn ON the ignition, with the engine OFF. Does the Red BRAKE indicator illuminate? If so, go to step  9. If not, go to next step.
  6. Test the signal circuit of the park brake switch for a high resistance or an open. For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to step  11.
  7. Test the signal circuit of the brake fluid level switch for a high resistance or an open. For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to next step.
  8. Test the ground circuit of the brake fluid level switch for a high resistance or an open. For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to step  11.
  9. Inspect for poor case ground or poor connections at the harness connector of the parking brake switch. For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to step  12.
  10. Inspect for poor connections at the harness connector of the brake fluid level switch. For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to step  13.
  11. Inspect for poor connections at the harness connector of the Instrument Panel Cluster (IPC). For wiring, see appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Did you find and correct the condition? If so, go to step  15. If not, go to step  14.
  12. Replace the parking brake switch. See PARKING BRAKE SWITCH  under REMOVAL & INSTALLATION. After repairs are complete, go to step  15.
  13. Replace the brake fluid level switch. See BRAKE FLUID LEVEL SWITCH  under REMOVAL & INSTALLATION. After repairs are complete, go to step  15.
  14. Replace the Instrument Panel Cluster (IPC). See INSTRUMENT PANEL CLUSTER under REMOVAL & INSTALLATION in appropriate ANALOG INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. After repairs are complete, go to next step.
  15. Operate the vehicle in order to verify the repair. Did you correct the condition? If so, repair is complete. If not, go to step  2.
