NOTE: Before you troubleshoot, review the general troubleshooting information.
1. Problem verification:
Is DTC 11-11, 13-11, 15-11, or 17-11 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting.
2. Shorted wire check (Wheel speed sensor lines to ground):
VSA modulator-control unit 21P connector
Is there continuity?
YES
Wheel speed sensor wires are shorted to ground. Go to step 3.
NO
The wheel speed sensor wires are not shorted. Go to step 4.
3. Wheel speed sensor(s) check:
Appropriate wheel speed sensor 2P connector
Is there continuity?
YES
The wheel speed sensor are shorted. Replace the appropriate wheel speed sensor.
NO
Repair a short to body ground in the wire between the VSA modulator-control unit and the wheel speed sensor.
4. Shorted wire check (Wheel speed sensor lines to power):
Is there 0.1 V or more?
YES
Wheel speed sensor wires are shorted to power. Go to step 5.
NO
The wheel speed sensor wires are not shorted to power. Go to step 6.
5. Wheel speed sensor(s) check:
Appropriate wheel speed sensor 2P connector
Is there 0.1 V or more?
YES
The wheel speed sensor are shorted to power. Replace the appropriate wheel speed sensor.
NO
Repair a short to power in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.
6. Shorted wire check (Wheel speed sensor lines wire to wire):
Appropriate wheel speed sensor 2P connector
Is there continuity?
YES
Repair a short in the wheel speed sensor wires between the appropriate wheel speed sensor and the VSA modulator-control unit.
NO
The wheel speed sensor wires are not shorted to each other. Go to step 7.
7. Open wire check (Wheel speed sensor lines) 1:
Check for continuity between the appropriate VSA modulator-control unit 21P connector terminal and the appropriate wheel speed sensor 2P connector terminal (see table).
Is there continuity?
YES
Go to step 8.
NO
Repair an open in the wheel speed sensor wires between the appropriate wheel speed sensor and the VSA modulator-control unit.
8. Open wire check (Wheel speed sensor lines) 2:
Check for continuity between the appropriate VSA modulator-control unit 21P connector terminal and the appropriate wheel speed sensor 2P connector terminal (see table).
Is there continuity?
YES
The wheel speed sensor wires are OK. If a DTC is indicated for either one of the front or rear wheels as described in step 1, go to step 9.
YES
The wheel speed sensor wires are OK. If DTCs are indicated for both front or rear wheels as described in step 1, go to step 10.
NO
Repair an open in the wheel speed sensor wires between the appropriate wheel speed sensor and the VSA modulator-control unit.
9. Wheel speed sensor(s) check:
VSA modulator-control unit 21P connector
Wheel speed sensor 2P connector
Is the DTC indicated for the opposite wheel?
YES
Replace the original wheel speed sensor.
NO
Go to step 11.
10. Wheel speed sensor(s) check (substitution):
VSA modulator-control unit 21P connector
Wheel speed sensor 2P connector
Is DTC 11-11, 13-11, 15-11, or 17-11 indicated?
YES
Go to step 11.
NO
Replace the original wheel speed sensor.
11. VSA modulator-control unit check (update):
Is DTC 11-11, 13-11, 15-11, or 17-11 indicated?
YES
Check for loose terminals in the VSA modulator-control unit 21P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit.
NO
Troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
