Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the suspect wheel speed sensor.
  2. Ignition ON, test for ignition voltage between the signal circuit terminal B and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Test for ignition voltage between the signal circuit terminal B and the low reference circuit terminal A.
    • If less than the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
  4. Disconnect the harness connector at the EBCM.
  5. Test for infinite resistance between the signal circuit terminal B and ground at the wheel speed sensor harness connector.
    • If not the specified value, test the signal circuit for a short to ground.
  6. If all circuits test normal, test or replace the wheel speed sensor.
