VSA DTC Troubleshooting: 11-13, 13-13, 15-13, 17-13

DTC 11-13: Right-front Wheel Speed Sensor Circuit Malfunction

DTC 13-13: Left-front Wheel Speed Sensor Circuit Malfunction

DTC 15-13: Right-rear Wheel Speed Sensor Circuit Malfunction

DTC 17-13: Left-rear Wheel Speed Sensor Circuit Malfunction

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

2. Clear the DTC with the HDS.

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

4. Check for DTCs with the HDS.

Is DTC 11-13, 13-13, 15-13, and/or 17-13 indicated?
YES - Go to step 5.

NO - Intermittent failure, the system is OK at this time. Check for loose terminals between the wheel speed sensor 2P connector and the VSA modulator-control unit 36P connector. Refer to intermittent failures troubleshooting. Initial Inspection and Diagnostic Overview


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

6. Disconnect the VSA modulator-control unit 36P connector. Service and Repair

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

8. Check for continuity between the appropriate VSA modulator-control unit 36P connector wheel speed sensor +B and GND terminals (see table).





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

NO - Go to step 9.






9. Check for continuity between the appropriate VSA modulator-control unit 36P connector terminal and the wheel speed sensor 2P connector terminal (see table).





Is there continuity?
YES - Go to step 10.

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






10. Check for continuity between the appropriate VSA modulator-control unit 36P connector terminal and the wheel speed sensor 2P connector terminal (see table).





Is there continuity?
YES - Go to step 11.

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






11. Check for continuity between body ground and the appropriate VSA modulator-control unit 36P connector terminal (see table).





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

NO - Go to step 12.






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

13. Measure the voltage between body ground and the appropriate VSA modulator-control unit 36P connector terminal (see table).





Is there 0.1 V or more?
YES - Repair short to power in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.

NO - Go to step 14.






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

15. Substitute the appropriate wheel speed sensor with opposite wheel speed sensor, or with a known-good wheel speed sensor.

16. Reconnect all connectors.

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

18. Clear the DTC with the HDS.

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

20. Check for DTCs with the HDS.

Is DTC indicated that is indicated in step 4?
YES - Go to step 21.

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


21. Update the VSA modulator-control unit if it does not have the latest software. Testing and Inspection If the unit already has the latest software, substitute a known-good VSA modulator-control unit. Service and Repair

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

23. Check for DTCs with the HDS.

Is DTC 11-13, 13-13, 15-13, and/or 17-13 indicated?
YES - Check for loose terminals in the VSA modulator-control unit 36P connector. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit, Service and Repair then retest. If the VSA modulator-control unit was substituted, go to step 1.

NO - If the VSA modulator-control unit was updated, troubleshooting is complete. If the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit. Service and Repair If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
