Test B: Brake Pad Wear Indicator Inoperative
- Inspect brake pads for wear, damage to sensors or damaged wiring and/or connectors. Repair as necessary and go to step 5 . If no problems are found, go to next step.
- Turn ignition on. 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 .
- 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. Repair circuit as necessary and go to step 5 . If circuit is okay, go to step 10 .
- 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 .
- Reconnect all harness connectors and reinstall all components. Turn ignition on. Disconnect one brake pad wear sensor harness connector. If brake pad wear indicator turns on, system is okay. If brake pad wear indicator does not turn on, go to step 2 .
- Remove instrument cluster and check brake pad wear indicator light bulb. Replace if necessary and go to step 5 . If light bulb is okay, go to step 8 .
- 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 . Repair circuit as necessary and go to step 5 . If circuit is okay, go to step 10 .
- Inspect gauge cluster harness connector for poor connections. Repair connector as necessary and go to step 5 . If connector is okay, go to next step.
- Replace gauge cluster. See INSTRUMENT CLUSTER GAUGES under REMOVAL & INSTALLATION. Go to step 5 .
- Fault is intermittent. Check related harness connectors for poor connections. Check for faulty wiring. Repair as necessary and go to step 5 .
