Is there 0.1 V or more?
YES -
Replace the appropriate wheel speed sensor Service and Repair.
NO -
Repair a short to power in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.
16. Turn the ignition switch to LOCK (0).
17. Disconnect the appropriate wheel speed sensor 2P connector Service and Repair.
18. 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 a short in the wires between the appropriate wheel speed sensor and the VSA modulator-control unit.
NO -
Go to step 19.
19. 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 20.
NO -
Repair an open in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.
20. 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 -
- If a DTC is indicated for either one of the left and right wheels as described in step 4, go to step 21.
- If DTCs are indicated for both the left and right wheels as described in step 4, go to step 27.
NO -
Repair an open in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.
21. Swap the appropriate left and right wheel speed sensors Service and Repair.
22. Reconnect all connectors.
23. Turn the ignition switch to ON (II).
24. Clear the DTC with the HDS.
25. Turn the ignition switch to LOCK (0) and then back to ON (II).
26. Check for DTCs with the HDS.
Is the DTC indicated for the opposite wheel?
YES -
Replace the original wheel speed sensor Service and Repair.
NO -
Go to step 33.
27. Substitute a known-good wheel speed sensor Service and Repair.
28. Reconnect all connectors.
29. Turn the ignition switch to ON (II).
30. Clear the DTC with the HDS.
31. Turn the ignition switch to LOCK (0) and then back to ON (II).
32. Check for DTCs with the HDS.
Is DTC 11-11, 13-11, 15-11, or 17-11 indicated?
YES -
Go to step 33.
NO -
Replace the original wheel speed sensor Service and Repair.
33. Update the VSA modulator-control unit if it does not have the latest software Testing and Inspection.
34. Turn the ignition switch to LOCK (0) and then back to ON (II).
35. Check for DTCs with the HDS.
Is DTC 11-11, 13-11, 15-11, or 17-11 indicated?
YES -
Check for loose terminals in the VSA modulator-control unit 36P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit Service and Repair, then retest.
NO -
Troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
