Component Testing

  1. Ignition OFF, disconnect the harness connector at the wheel speed sensor.
  2. Connect a jumper wire between signal circuit on the harness side and the wheel speed sensor signal circuit terminal 2 on the front WSS or terminal B on the rear WSS.
  3. Connect a DMM between the low reference terminal 1 on the front WSS, or terminal A on the rear and ground. Set up the DMM to measure mA using the DC scale.
  4. Spin the wheel very slowly. Using the DMM MIN/MAX feature, test for 4-8 mA on the MIN capture and 12-16 mA on the MAX capture.
    • If not within the specified range, replace the wheel speed sensor.
