Circuit/System Testing

WARNING: This page is about a different car, the 2008 Pontiac G5 and 2008 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 steering angle sensor.
  2. Test for less than 6 ohms between the low reference circuit terminal 6 and ground.
    • If greater than the specified range, test for an open/high resistance in the low reference circuit. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, test for 11.8-12.2 volts between the 12-volt reference circuit terminal 1 and ground.
    • If less than the specified range, test the 12-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If greater than the specified range, test the 12-volt reference circuit for a short to voltage. If the circuit tests normal, replace the EBCM.
  4. Ignition OFF, disconnect the harness connector at the EBCM.
  5. Ignition ON, test for 0 volts between the communication circuit terminal 18 and ground.
    • If greater than the specified value, test the communication circuit for a short to voltage.
  6. Test for 0 volts between the communication circuit terminal 19 and ground.
    • If greater than the specified value, test the communication circuit for a short to voltage.
  7. Ignition OFF, test for infinite resistance between the communication circuit terminal 18 and ground.
    • If not the specified value, test the communication circuit for a short to ground.
  8. Test for infinite resistance between the communication circuit terminal 19 and ground.
    • If not the specified value, test the communication circuit for a short to ground.
  9. Test for less than 1 ohm between the communication circuit terminals 18 and terminal 3.
    • If greater than the specified range, test the communication circuit for an open/high resistance.
  10. Test for less than 1 ohm between the communication circuit terminals 19 and terminal 4.
    • If greater than the specified range, test the communication circuit for an open/high resistance.
  11. Test for infinite resistance between the communication circuit 18 and the communication circuit 19.
    • If not the specified value, test the communication circuits for a short together.
  12. If all circuits test normal, replace the Steering Angle Sensor.
