DTC 12

DTC 12: Wheel Sensor (Electrical Noise/Intermittent Interruption)

NOTE: If the ABS indicator comes on because of electrical noise, the indicator goes off when you test-drive the vehicle at 19 mph (30 km/h).

1. Clear the DTC using the HDS.
2. Disconnect the HDS from the 16P DLC.
3. Turn the ignition switch OFF, then turn it ON (II) again.
4. Test-drive the vehicle around a number of corners.





5. Check the appropriate wheel sensor and magnetic encoder or pulser for debris or damage.
Are they OK?
YES - Go to step 6.
NO - Clean and reinstall or replace the appropriate wheel sensor, magnetic encoder or pulsar.
6. Disconnect the VSA control unit 47P connector.





7. Check for continuity between the appropriate wheel sensor + B terminal and other wheel sensor + B terminals of the VSA control unit 47P connector (see table).
Is there continuity?
YES - Repair short in the wire between the appropriate wheel sensor and the other wheel sensor.
NO - Go to step 8.





8. Substitute a known-good wheel sensor for the appropriate wheel sensor (see table).
Does the ABS indicator come on?
YES - Check for loose terminals in the VSA control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit, and recheck.
NO - Replace the original wheel sensor or encoder.
