DTC 12

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

NOTE: If the ABS indicator comes on because of electrical noise, the indicator will go off when you drive the vehicle over 19 mph (30 km/h) and the noise is gone.





1. Inspect the appropriate wheel sensor and magnetic encoder.
Are they OK?
YES - Go to step 2.
NO - Reinstall or replace the appropriate wheel sensor or magnetic encoder.
2. Disconnect the ABS control unit 47P connector.





3. Check for continuity between the appropriate wheel sensor GND terminal and all other wheel sensor GND terminals (see table)
Is there continuity?
YES - Repair short in the wires between the appropriate wheel sensor and the other wheel sensor.
NO - Go to step 4.
4. Replace the appropriate wheel sensor and test drive the vehicle.
Does the ABS indicator come ON?
YES - Clear the DTC, and test-drive the vehicle. If the ABS indicator comes on and the same DTC is indicated, replace the ABS modulator-control unit.
NO - The sensor was faulty. Troubleshooting is complete.
