Honda HR-V: DTC Troubleshooting 11-12, 13-12, 15-12, 17-12: Wheel Speed Sensor Power Source Malfunction

NOTE: Before you troubleshoot, review the general troubleshooting information.

1. Problem verification:

1. Turn the vehicle to the ON mode.
2. Clear the DTC with the HDS.
3. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
4. Check for DTCs with the HDS.

Is DTC 11-12, 13-12, 15-12, or 17-12 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 power) 1:

1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the following connector.

VSA modulator-control unit 21P connector

3. Turn the vehicle to the ON mode.
4. Measure the voltage between body ground and the appropriate wheel speed sensor GND terminals of the VSA modulator-control unit 21P connector individually (see table).

Is there 0.1 V or more?

YES

Wheel speed sensor wires are shorted to power. Go to step 3.

NO

The wheel speed sensor wires are not shorted to power. Go to step 4.

3. Shorted wire check (Wheel speed sensor lines to power) 2:

1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the following connector.

Appropriate wheel speed sensor 2P connector

3. Turn the vehicle to the ON mode.
4. Measure the voltage between body ground and the appropriate wheel speed sensor GND terminals of the VSA modulator-control unit 21P connector individually (see table).

Is there 0.1 V or more?

YES

Repair a short to power in the wire between the VSA modulator-control unit and the appropriate wheel speed sensor.

NO

The wheel speed sensor wires are not shorted to power. Replace the appropriate wheel speed sensor.

4. Shorted wire check (Wheel speed sensor lines wire to wire):

1. Turn the vehicle to the OFF (LOCK) mode.
2. Check for continuity between the appropriate VSA modulator-control unit 21P connector wheel speed sensor +B terminals (see table).

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 OK. Go to step 5.

5. VSA modulator-control unit check (update):

1. Reconnect the following connector.

VSA modulator-control unit 21P connector

2. Update the VSA modulator-control unit if it does not have the latest software.
3. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
4. Check for DTCs with the HDS.

Is DTC 11-12, 13-12, 15-12, or 17-12 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.
