DTC 12

DTC 12, 14, 16, 18: 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 magnetic encoder (see table).
Are they, OK?
YES - Go to step 2.
NO - Reinstall or replace the appropriate wheel sensor or magnetic encoder.
2. Disconnect the VSA modulator-control unit 47P connector.





3. Check for continuity between the appropriate wheel sensor GND terminal and other wheel sensor GND terminals (see table).
Is there continuity?
YES - Repair short in the wire between the appropriate wheel sensor and the other wheel sensor.
NO - Clear the DTC using the HDS, and test-drive the vehicle. If the ABS indicator comes on and the same DTC is indicated, replace the appropriate wheel sensor. If after clearing the DTC and test driving the vehicle, the ABS indicator comes on and the same DTC is indicated, replace the VSA modulator-control unit.
