Speed Sensor Test

  1. Turn ignition off. Connect ABS Tester (07HAJ-SG0010A) to MD13Pink 6-pin test connector, located on passenger's side of center console. Turn ignition on. Place ABS tester mode selector to "0".
  2. Raise and support vehicle so wheels can turned. Place transmission in Neutral. Turn wheels by hand at one revolution per second. Appropriate monitor light should blink each time wheel is rotated.
  3. 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 does not blink, check appropriate wheel sensor, sensor air gap and wiring.
