VSA DTC Troubleshooting: 11, 13, 15, 17

DTC 11, 13, 15, 17: Wheel Speed Sensor (Open/Short to Body Ground/Short to Power)

1. Turn the ignition switch to ON (II).

2. Clear the DTCs with the HDS.

3. Turn the ignition switch to LOCK (0), then turn it to ON (II).

4. Check for DTCs with the HDS.

Does the ABS indicator come on and are DTC 11, 13, 15, and/or 17 indicated?
YES - Go to step 5.

NO - Intermittent failure, the system is OK at this time. Check for loose or poor connections.


5. Turn the ignition switch to LOCK (0).

6. Disconnect the VSA modulator-control unit 46P connector.

7. Turn the ignition switch to ON (II).

8. Measure the voltage between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 46P connector individually (see table).





Is there 0.2 V or more?
YES - Repair short to power in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.

NO - Go to step 9.






9. Turn the ignition switch to LOCK (0).

10. Check for continuity between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 46P connector individually (see table).





Is there continuity?
YES - Go to step 11.

NO - Go to step 13.






11. Disconnect the appropriate wheel speed sensor 2P connector.

12. Check for continuity between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 46P connector individually (see table).





Is there continuity?
YES - Repair short to body ground in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.

NO - Replace the appropriate wheel speed sensor. Service and Repair






13. Disconnect the appropriate wheel speed sensor 2P connector.

14. Check for continuity between the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 46P connector (see table).





Is there continuity?
YES - Repair short in the wires between the VSA modulator-control unit and the appropriate wheel speed sensor.

NO - Go to step 15.






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















16. Check for continuity between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 46P connector individually (see table).





Is there continuity?
YES - Go to step 17.

NO - Repair open in the wire between the VSA modulator-control unit and the wheel speed sensor.






17. Substitute a known-good wheel speed sensor for the appropriate wheel speed sensor (see table).





18. Reconnect all connectors.

19. Turn the ignition switch to ON (II).

20. Clear the DTCs with the HDS.

21. Turn the ignition switch to LOCK (0), then turn it to ON (II).

22. Check for DTCs with the HDS.

Does the ABS indicator come on and are DTC 11, 13, 15, and/or 17 indicated?
YES - Check for loose terminals in the VSA modulator-control unit 46P connector. If connections are good, replace the VSA modulator-control unit, Service and Repair and recheck.

NO - Replace the original wheel speed sensor. Service and Repair
