Wheel Sensor Check
- Disconnect ABS inspection 6-pin connector. See Figure . Connect ABS tester to 6-pin connector. Set ABS tester mode selector in mode 0. Raise and support vehicle so wheels can be rotated. Turn ignition on. Place transmission in Neutral. Manually rotate wheels (one revolution per second). Ensure appropriate monitor light on tester blinks as wheel is rotated.
- In some instances, front wheels may not rotate fast enough to make tester light blink. If this happens, start engine. Slowly accelerate and decelerate front wheels. If light still does not blink, check suspect wheel sensor, sensor air gap and wiring.
