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 0 V between the appropriate low reference circuit terminal listed below and ground:
    • Left Front Sensor circuit terminal 8 (JM4)
    • Left Front Sensor circuit terminal 46 (JL4)
    • Right Front Sensor circuit terminal 6 (JM4)
    • Right Front Sensor circuit terminal 33 (JL4)
    • Left Rear Sensor circuit terminal 2 (JM4)
    • Left Rear Sensor circuit terminal 37 (JL4)
    • Right Rear Sensor circuit terminal 12 (JM4)
    • Right Rear Sensor circuit terminal 42 (JL4)
    • If not the specified value, test the low reference circuit for a short to voltage. If the circuit tests normal, replace the EBCM.
  3. Test for 0 V between the appropriate signal circuit terminal listed below and ground:
    • Left Front Sensor circuit terminal 9 (JM4)
    • Left Front Sensor circuit terminal 45 (JL4)
    • Right Front Sensor circuit terminal 5 (JM4)
    • Right Front Sensor circuit terminal 34 (JL4)
    • Left Rear Sensor circuit terminal 3 (JM4)
    • Left Rear Sensor circuit terminal 36 (JL4)
    • Right Rear Sensor circuit terminal 11 (JM4)
    • Right Rear Sensor circuit terminal 43 (JL4)
    • If not the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, replace the EBCM.
  4. Ignition OFF, test for infinite resistance between the appropriate low reference terminal listed below and ground:
    • Left Front Sensor circuit terminal 8 (JM4)
    • Left Front Sensor circuit terminal 46 (JL4)
    • Right Front Sensor circuit terminal 6 (JM4)
    • Right Front Sensor circuit terminal 33 (JL4)
    • Left Rear Sensor circuit terminal 2 (JM4)
    • Left Rear Sensor circuit terminal 37 (JL4)
    • Right Rear Sensor circuit terminal 12 (JM4)
    • Right Rear Sensor circuit terminal 42 (JL4)
    • If not the specified value, test the low reference circuit for a short to ground. If the circuit tests normal, replace the EBCM.
  5. Test for infinite resistance between the appropriate signal circuit terminal listed below and ground:
    • Left Front Sensor circuit terminal 9 (JM4)
    • Left Front Sensor circuit terminal 45 (JL4)
    • Right Front Sensor circuit terminal 5 (JM4)
    • Right Front Sensor circuit terminal 34 (JL4)
    • Left Rear Sensor circuit terminal 3 (JM4)
    • Left Rear Sensor circuit terminal 36 (JL4)
    • Right Rear Sensor circuit terminal 11 (JM4)
    • Right Rear Sensor circuit terminal 43 (JL4)
    • If not the specified value, test the signal circuit for a short to ground. If the circuit tests normal, replace the EBCM.
  6. Test for 1200-2700 Ω between the appropriate wheel speed sensor circuit terminal listed below:
    • Left Front Sensor circuit terminal 8 and 9 (JM4)
    • Left Front Sensor circuit terminal 45 and 46 (JL4)
    • Right Front Sensor circuit terminal 5 and 6 (JM4)
    • Right Front Sensor circuit terminal 33 and 34 (JL4)
    • Left Rear Sensor circuit terminal 2 and 3 (JM4)
    • Left Rear Sensor circuit terminal 36 and 37 (JL4)
    • Right Rear Sensor circuit terminal 11 and 12 (JM4)
    • Right Rear Sensor circuit terminal 42 and 43 (JL4)
    • If not within the specified range, test the low reference and signal circuits for an open/high resistance. If the circuit tests normal, replace the wheel speed sensor.
  7. If all circuits test normal, replace the EBCM.
