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 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 (front) and pulser (rear).





Are they OK?
YES - Go to step 2.
NO - Reinstall or replace the appropriate wheel sensor or magnetic encoder (front) and pulser (rear).
2. Disconnect the ABS modulator-control unit 25P 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 wires between the appropriate wheel sensor and the other wheel sensor.
NO - 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.
