Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. 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 V between the low reference circuit terminals of the appropriate sensor listed below and ground.
    • Left front sensor circuit terminal 46
    • Right front sensor circuit terminal 33
    • Left rear sensor circuit terminal 37
    • Right rear sensor circuit terminal 42
    • If greater than the specified range, test the low reference circuit for a short to voltage.
  3. Test for less than 1 V between the signal terminals of the appropriate sensor listed below and ground.
    • Left front sensor circuit terminal 45
    • Right front sensor circuit terminal 34
    • Left rear sensor circuit terminal 36
    • Right rear sensor circuit terminal 43
    • If greater than the specified range, test the signal circuit for a short to voltage.
  4. Ignition OFF, test for infinite resistance between the low reference terminals of the appropriate sensor listed below and ground.
    • Left front sensor circuit terminal 46
    • Right front sensor circuit terminal 33
    • Left rear sensor circuit terminal 37
    • Right rear sensor circuit terminal 42
    • If not the specified value, test the low reference circuit for a short to ground.
  5. Test for infinite resistance between the appropriate signal terminal listed below and ground.
    • Left front sensor circuit terminal 45
    • Right front sensor circuit terminal 34
    • Left rear sensor circuit terminal 36
    • Right rear sensor circuit terminal 43
    • If not the specified value, test the signal circuit for a short to ground.
  6. Ignition OFF, disconnect the harness connector at the appropriate wheel speed sensor.
  7. Ignition OFF, test for less than 2 Ω between the appropriate signal terminals listed below.
    • Left front sensor circuit terminal 45 at the EBCM harness connector and terminal A at the wheel speed sensor harness connector.
    • Right front sensor circuit terminal 34 at the EBCM harness connector and terminal A at the wheel speed sensor harness connector.
    • Left rear sensor circuit terminal 36 at the EBCM harness connector and terminal A at the wheel speed sensor harness connector.
    • Right rear sensor circuit terminal 43 at the EBCM harness connector and terminal A at the wheel speed sensor harness connector.
    • If greater than the specified value, test the signal circuit for an open or high resistance.
  8. Test for less than 2 Ω between the appropriate low reference terminals listed below.
    • Left front sensor circuit terminal 46 at the EBCM harness connector and terminal B at the wheel speed sensor harness connector.
    • Right front sensor circuit terminal 33 at the EBCM harness connector and terminal B at the wheel speed sensor harness connector.
    • Left rear sensor circuit terminal 37 at the EBCM harness connector and terminal B at the wheel speed sensor harness connector.
    • Right rear sensor circuit terminal 42 at the EBCM harness connector and terminal B at the wheel speed sensor harness connector.
    • If greater than the specified value, test the low reference 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.
