DTC 13

DTC 11, 13, 15, 17: Wheel Sensor (Open/Short to Body Ground/Short to Power)
1. Clear the DTC using the HDS.
2. Disconnect the HDS.
3. Turn the ignition switch OFF, then turn it ON (II) again.
4. Test-drive the vehicle.
Does the ABS indicator come on?
YES - Go to step 5.
NO - intermittent failure, the system is OK at this time. Check for loose or poor connections.
5. Disconnect the ABS/TCS control unit 47P connector.
6. Start the engine.








7. Measure the voltage between body ground and the appropriate wheel sensor +B and GND terminals of the ABS/TCS control unit 47P connector individually (see table).
Is there battery voltage?
YES - Repair short to power in the wire between the ABS/TCS modulator-control unit and the appropriate wheel sensor.
NO - Go to step 8.
8. Turn the ignition switch OFF.








9. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS/TCS control unit 47P connector individually (see table).
Is there continuity?
YES - Go to step 10.
NO - Go to step 12.
10. Disconnect the appropriate wheel sensor 2P connector.








11. Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS/TCS control unit 47P connector individually (see table).
Is there continuity?
YES - Repair short to body ground in the wire between the ABS/TCS modulator-control unit and the wheel sensor.
NO - Replace the wheel sensor.
12. Disconnect the appropriate wheel sensor 2P connector.








13. Check for continuity between the appropriate wheel sensor +B and GND terminals of the ABS/ TCS control unit 47P connector (see table), then recheck for continuity between the same terminals after reversing the positive tester probe and negative tester probe.
Is there continuity in both directions?
YES - Go to step 14.
NO - Check for a loose ABS/TCS control unit 47P connector. If necessary, substitute a known-good ABS/TCS modulator-control unit, and recheck.





14. Substitute a known-good wheel sensor for the appropriate wheel sensor (see table).
15. Clear the DTC using the HDS.
16. Disconnect the HDS from the 16P DLC.
17. Turn the ignition switch OFF, then turn it ON (II) again. Test-drive the vehicle at speeds above 19 mph (30 km/h).
Does the ABS indicator come on?
YES - Check for a loose ABS/TCS control unit 47P connector. If necessary, substitute a known-good ABS/TCS modulator-control unit, and recheck.
NO - Replace the original wheel sensor.
