NO -
Repair a short to body ground in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.�
11. Turn the ignition switch to ON (II).
12. Measure the voltage between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).
Is there 0.1V or more?
YES -
Go to step 13.
NO -
Go to step 17.
13. Turn the ignition switch to LOCK (0).
14. Disconnect the appropriate wheel speed sensor 2P connector Wheel Speed Sensor Replacement (VSA).
15. Turn the ignition switch to ON (II).
16. On the sensor side, measure the voltage between body ground and wheel speed sensor 2P connector terminals No. 1 and No. 2 individually.
Is there 0.1 V or more?
YES -
Replace the appropriate wheel speed sensor Wheel Speed Sensor Replacement (VSA).�
NO -
Repair a short to power in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.�
17. Turn the ignition switch to LOCK (0).
18. Disconnect the appropriate wheel speed sensor 2P connector Wheel Speed Sensor Replacement (VSA).
19. Check for continuity between the appropriate VSA modulator-control unit 47P 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 20.
20. Check for continuity between the appropriate VSA modulator-control unit 47P connector terminal and the wheel speed sensor 2P connector terminal (see table).
Is there continuity?
YES -
Go to step 21.
NO -
Repair an open in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.�
21. Check for continuity between the appropriate VSA modulator-control unit 47P connector terminal and the wheel speed sensor 2P connector terminal (see table).
Is there continuity?
YES -
- If the DTCs indicate one wheel speed sensor (either the right or left) on the same axle (front or rear), go to step 22.
- If the DTCs indicate both wheel speed sensors (right and left) on the same axle (front or rear), go to step 29.
NO -
Repair an open in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.�
22. Swap the applicable left and right wheel speed sensors.
23. Reconnect all connectors.
24. Turn the ignition switch to ON (II).
25. Clear the DTC with the HDS.
26. Turn the ignition switch to LOCK (0).
27. Test-drive the vehicle at 19 mph (30 km/h) or more.
NOTE: Drive the vehicle on the road, not on a lift.
28. Check for DTCs with the HDS.
Is the DTC indicated for the opposite wheel?
YES -
Replace the original wheel speed sensor Wheel Speed Sensor Replacement (VSA).�
NO -
Go to step 29.
29. Substitute a known-good wheel speed sensor Wheel Speed Sensor Replacement (VSA).
30. Reconnect all connectors.
31. Turn the ignition switch to ON (II).
32. Clear the DTC with the HDS.
33. Turn the ignition switch to LOCK (0).
34. Test-drive the vehicle at 19 mph (30 km/h) or more.
NOTE: Drive the vehicle on the road, not on a lift.
35. Check for DTCs with the HDS.
Is DTC 11, 13, 15, or 17 indicated?
YES -
Go to step 36.
NO -
Replace the original speed sensor Wheel Speed Sensor Replacement (VSA).�
36. Update the VSA modulator-control unit if it does not have the latest software. If the unit already has the latest software, substitute a known-good VSA modulator-control unit.
37. Turn the ignition switch to LOCK (0).
38. Test-drive the vehicle at 19 mph (30 km/h) or more.
NOTE: Drive the vehicle on a straight section of road, not on a lift.
39. Check for DTCs with the HDS.
Is DTC 11, 13, 15, or 17 indicated?
YES -
Check for loose terminals in the VSA modulator-control unit 47P connector. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit, 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. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.�
