Test J: Brake Pad Wear Indicator Inoperative

  1. Inspect brake pads for wear, damage to sensors or damaged wiring and/or connectors. If no problems are found, go to next step. If problem is found, repair as necessary and go to step  5 .
  2. Turn ignition switch to RUN position. Disconnect left brake pad wear sensor harness connector. If brake pad wear indicator turns on, go to next step. If brake pad wear indicator does not turn on, go to step  4 .
  3. Disconnect right brake pad wear sensor harness connector. Check for short to ground in Gray/Red wire between left brake pad wear sensor harness connector terminal No. 3 and right brake pad wear sensor harness connector terminal No. 2. If problem is found, repair as necessary and go to step  5 . If no problem is found, go to step  10 .
  4. Measure voltage between ground and left brake pad wear sensor harness connector terminal No. 2 (Yellow/Red wire). If voltage is about 12 volts, go to step  6 . If voltage is not about 12 volts, go to step  7 .
  5. Reconnect all harness connectors and reinstall all components. Turn ignition switch to RUN position. Disconnect one brake pad wear sensor harness connector. If brake pad wear indicator turns on, system is okay.
  6. Remove instrument cluster and check brake pad wear indicator light bulb. If problem is found, replace as necessary and go to step  5 . If no problem is found, go to step  8 .
  7. Check for short to ground in Yellow/Red wire between left brake pad wear sensor harness connector terminal No. 2 and gauge cluster harness connector terminal No. 2. See Figure . If problem is found, repair circuit as necessary and go to step  5 . If no problem is found, go to step  10 .
  8. Inspect gauge cluster harness connector for poor connections. If no problem is found, go to next step. If problem is found, repair connector as necessary and go to step  5 .
  9. Replace gauge cluster. See GAUGE CLUSTER  under REMOVAL & INSTALLATION. After repairs are made, go to step  5 .
  10. Fault is intermittent. See PROBLEM DIAGNOSIS  under INTERMITTENTS. If problem is found, repair as necessary and go to step  5 .
