Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G6. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Ignition ON, test for less than 1 volt between the ignition voltage circuit terminal of the appropriate sensor listed below and ground.
    • LF Sensor circuit terminal 12
    • RF Sensor circuit terminal 26
    • LR Sensor circuit terminal 42
    • RR Sensor circuit terminal 43
    • If greater than the specified range, test the ignition voltage circuit for a short to voltage.
  3. Test for less than 1 volt between the signal circuit terminal of the appropriate sensor listed below and ground.
    • LF Sensor circuit terminal 13
    • RF Sensor circuit terminal 27
    • LR Sensor circuit terminal 41
    • RR Sensor circuit terminal 44
    • If greater than the specified range, test the signal circuit for a short to voltage.
  4. Ignition OFF, test for infinite resistance between the ignition voltage terminal of the appropriate sensor listed below and ground.
    • LF Sensor circuit terminal 12
    • RF Sensor circuit terminal 26
    • LR Sensor circuit terminal 42
    • RR Sensor circuit terminal 43
    • If less than the specified value, test the ignition voltage circuit for a short to ground.
  5. Test for infinite resistance between the following signal circuit terminals of the appropriate sensor listed below and ground.
    • LF Sensor circuit terminal 13
    • RF Sensor circuit terminal 27
    • LR Sensor circuit terminal 41
    • RR Sensor circuit terminal 44
    • If less than the specified value, test the signal circuit for a short to ground.
  6. Ignition OFF, disconnect the harness connector at the appropriate WSS.
  7. Ignition OFF, test for less than 2 ohms between the appropriate ignition voltage circuit terminals listed below.
    • LF Sensor circuit terminal 12 at the EBCM harness connector and terminal A at the WSS harness connector.
    • RF Sensor circuit terminal 26 at the EBCM harness connector and terminal A at the WSS harness connector.
    • LR Sensor circuit terminal 42 at the EBCM harness connector and terminal A at the WSS harness connector.
    • RR Sensor circuit terminal 43 at the EBCM harness connector and terminal A at the WSS harness connector.
    • If greater than the specified value, test the ignition voltage circuit for an open or high resistance.
  8. Test for less than 2 ohms between the appropriate signal circuit terminals listed below.
    • LF Sensor circuit terminal 13 at the EBCM harness connector and terminal B at the WSS harness connector.
    • RF Sensor circuit terminal 27 at the EBCM harness connector and terminal B at the WSS harness connector.
    • LR Sensor circuit terminal 41 at the EBCM harness connector and terminal B at the WSS harness connector.
    • RR Sensor circuit terminal 44 at the EBCM harness connector and terminal B at the WSS harness connector.
    • If greater than the specified value, test the signal circuit for an open or high resistance.
  9. If all circuits test normal, replace the appropriate wheel speed sensor. If the DTC resets replace the EBCM.
