Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- Inspect the back of the wheel bearing on the encoder surface for metal debris that could cause an erratic reading with the sensor.
- Do not use a magnet to clean debris, or damage to the encoder ring may occur.
- If two or more wheel speed sensors are inoperative diagnose each wheel speed sensor individually.
- If the customer comments that the ABS indicator is ON only during moist environmental conditions: rain, snow, vehicle wash, etc., inspect the wheel speed sensor wiring for signs of water intrusion.
