DTC 17

DTC 11, 13, 15, 17: Wheel Sensor (Short to Power/Short to Body Ground/Open)
1. Turn the ignition switch OFF.
2. Disconnect the VSA modulator-control unit 47P connector.
3. Start the engine.
4. Measure the voltage between body ground and the appropriate wheel sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).





Is there 0.1 V or more?
YES - Repair short to power in the wire between the VSA modulator-control unit and the appropriate wheel sensor.
NO - Go to step 5.

5. Turn the ignition switch OFF.
6. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).





Is there continuity?
YES - Go to step 7.
NO - Go to step 9.

7. Disconnect the appropriate wheel sensor 2P connector.
8. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).





Is there continuity?
YES - Repair short to body ground in the wire between the VSA modulator-control unit and the wheel sensor.
NO - Replace the wheel sensor.

9. Disconnect the appropriate wheel sensor 2P connector.
10. Check for continuity between the appropriate wheel sensor B+ and GND terminals of the VSA modulator-control unit 47P connector (see table).





Is there continuity?
YES - Repair short in the wires between the VSA modulator-control unit and the wheel sensor.
NO - Go to step 11.

11. Connect wheel sensor 2P connector terminals No. 1 and No. 2 to body ground with a jumper wire.





12. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).





Is there continuity?
YES - Go to step 13.
NO - Repair open in the wire between the VSA modulator-control unit and the wheel sensor.

13. Measure the resistance between the appropriate wheel sensor 2P connector terminals, then remeasure the resistance between the same terminals after reversing the positive tester probe and negative tester probe.





Is the resistance infinity (open circuit) or has continuity in both directions?
YES - Replace the wheel sensor.
NO - Check for loose terminals in the VSA modulator-control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit, and retest.
