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. Check the appropriate wheel sensor and pulser for damage and proper air gap.
Are they OK?
YES - Go to step 2.
NO - Reinstall or replace the appropriate wheel sensor or pulsar.
2. Disconnect the VSA control unit 47P connector.





3. Check for continuity between the appropriate wheel sensor (+) circuit terminal and other wheel sensor (+) circuit terminal (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 4.





4. Substitute a known-good wheel sensor for the appropriate wheel sensor (see table).
5. Clear the DTC.
6. Disconnect the HDS from the 16P DLC.
7. Turn the ignition switch OFF, then turn it ON (II) again. Test-drive the vehicles at speed above 19 mph (30 km/h).
Does the ABS indicator come on?
YES - Check for a loose VSA control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit, and recheck.
NO - Replace the original wheel sensor.
