Short Circuit-To-Ground Check

  1. Turn ignition off. Disconnect connector at ABS control module. See Figure . Set VOM on 200-k/ohm scale. Measure and record resistance between each of following connector wire terminals:
    • White Wire (Left Front Wheel Speed Sensor) and chassis ground.
    • Yellow wire (Right Front Wheel Speed Sensor) and chassis ground.
    • Red wire (Left Rear Wheel Speed Sensor) and chassis ground.
    • Green wire (Right Rear Wheel Speed Sensor) and chassis ground.
  2. If all resistances are greater than 10 k/ohms, go to PINPOINT TEST WSS-3  . If resistances are NOT more than 10 k/ohms, repair short circuit-to-ground in wires in question between ABS control module and wheel speed sensors. Go to PINPOINT TEST WSS-3  .
