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 ABS modulator-control unit 25P connector. Refer to intermittent failures troubleshooting.�
5. Turn the ignition switch to LOCK (0).
6. Disconnect the ABS modulator-control unit 25P connector.
7. Check for continuity between body ground and the appropriate wheel speed sensor +B and GND terminals of the ABS modulator-control unit 25P connector individually (see table).
Is there continuity?
YES -
Go to step 8.
NO -
Go to step 10.
8. Disconnect the appropriate wheel speed sensor 2P connector Wheel Speed Sensor Replacement (Without VSA).
9. On the sensor side, check for continuity between body ground and wheel speed sensor 2P connector terminals No. 1 and No. 2 individually.
Is there continuity?
YES -
Replace the appropriate wheel speed sensor Wheel Speed Sensor Replacement (Without VSA).�
NO -
Repair a short to body ground in the wire between the ABS modulator-control unit and the wheel speed sensor.�
10. Turn the ignition switch to ON (II).
11. Measure the voltage between body ground and the appropriate wheel speed sensor +B and GND terminals of the ABS modulator-control unit 25P connector individually (see table).
Is there 0.1 V or more?
YES -
Go to step 12.
NO -
Go to step 16.
12. Turn the ignition switch to LOCK (0).
13. Disconnect the appropriate wheel speed sensor 2P connector Wheel Speed Sensor Replacement (Without VSA).
14. Turn the ignition switch to ON (II).
15. 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 (Without VSA).�
NO -
Repair a short to power in the wire between the ABS 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 Wheel Speed Sensor Replacement (Without VSA).
18. Check for continuity between the appropriate ABS modulator-control unit 25P 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 ABS modulator-control unit.�
NO -
Go to step 19.
19. Check for continuity between the appropriate ABS modulator-control unit 25P 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 ABS modulator-control unit.�
20. Check for continuity between the appropriate ABS modulator-control unit 25P 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 ABS modulator-control unit.�
21. Swap the appropriate left and right wheel speed sensors Wheel Speed Sensor Replacement (Without VSA).
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 Wheel Speed Sensor Replacement (Without VSA).�
NO -
Go to step 33.
27. Substitute a known-good wheel speed sensor Wheel Speed Sensor Replacement (Without VSA).
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 11-13, 13-13, 15-13, or 17-13 indicated?
YES -
Go to step 33.
NO -
Replace the original wheel speed sensor Wheel Speed Sensor Replacement (Without VSA).�
33. Substitute a known-good ABS modulator-control unit Service and Repair.
34. Turn the ignition switch to LOCK (0) and then back to ON (II).
35. Check for DTCs with the HDS.
Is DTC 11-13, 13-13, 15-13, or 17-13 indicated?
YES -
Check for loose terminals in the ABS modulator-control unit 25P connector. If necessary, substitute a known-good ABS modulator-control unit Service and Repair, and retest. If the ABS modulator-control unit was substituted, go to step 1.
NO -
If the ABS modulator-control unit was substituted, replace the original ABS modulator-control unit. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.�
