DTC 11

DTC 11, 13, 15, 17: Wheel Sensor (Open/Short to Body Ground/Short to Power)
1. Disconnect the ABS modulator-control unit 25P connector.
2. Start the engine.
3. Measure the voltage between body ground and the appropriate wheel sensor +B and GND terminals of the ABS modulator-control unit 25P connector individually (see table).





Is there battery voltage?
YES - Repair short to power in the wire between the ABS modulator-control unit and the appropriate wheel sensor.
NO - Go to step 4.
4. Turn the ignition switch OFF.
5. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS modulator-control unit 25P connector individually (see table).





Is there continuity?
YES - Go to step 6.
NO - Go to step 8.
6. Disconnect the appropriate wheel sensor 2P connector.
7. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS modulator-control unit 25P connector individually (see table).





Is there continuity?
YES - Repair short to body ground in the wire between the ABS modulator-control unit and the wheel sensor.
NO - Replace the wheel sensor.
8. Measure the resistance between the appropriate wheel sensor +B and GND terminals of the ABS modulator-control unit 25P connector (see table), then measure the resistance between the same terminals and reverse the positive and negative tester probes.





Is the resistance infinity (open circuit) in both directions?
YES - Go to step 9.
NO - Go to step 11.
9. Disconnect the appropriate wheel sensor 2P connector.
10. Measure the resistance between the appropriate wheel sensor 2P connector terminals, then measure the resistance between the same terminals arid reverse the positive and negative tester probes.





Is the resistance infinity (open circuit) in both directions?
YES - Replace the wheel sensor.
NO - Repair open in the wire between the ABS modulator-control unit and the wheel sensor.
11. Disconnect the appropriate wheel sensor 2P connector.
12. Check for continuity between the appropriate wheel sensor +B and GND terminals of the ABS modulator-control unit 25P connector (see table), then check for continuity between the same terminals and reverse the positive and negative tester probes.





Is there continuity in both directions?
YES - Repair the wires between the ABS modulator-control unit and the wheel sensor that are shorted to each other.
NO - Check for loose or poor connections at the ABS modulator-control unit 25P connector and the appropriate wheel sensor 2P connector. If the connections are good, replace the appropriate wheel sensor and recheck for DTCs. If the DTC returns, replace the ABS modular-control unit.
