Circuit/System Testing

WARNING: This page is about a different car, the 2008 Chevrolet Impala. 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 1 ohm of resistance between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test for an open/high resistance in the ground circuit. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. 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 EBCM Bus- communication terminal 33 and ground.
    • If greater than the specified value, test the communication circuit for a short to voltage.
  6. Test for 0 volts between the EBCM Bus- communication circuit terminal 21 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 EBCM Bus- communication circuit terminal 33 and ground.
    • If not the specified value, test the communication circuit for a short to ground.
  8. Test for infinite resistance between the EBCM Bus- communication circuit terminal 21 and ground.
    • If not the specified value, test the communication circuit for a short to ground.
  9. Test for less than 1 ohm of resistance between the EBCM communication circuit terminal 33 and Yaw Lateral Accelerometer Sensor terminal 2.
    • If greater than the specified range, test the communication circuits for an open/high resistance.
  10. Test for less than 1 ohm of resistance between the EBCM communication circuit terminal 21and Yaw Lateral Accelerometer terminal 3.
    • If greater than the specified range, test the communication circuits for an open/high resistance.
  11. Test for infinite resistance between the EBCM communication circuit terminal 21and terminal 33.
    • If not the specified value, test the communication circuits for a short together.
  12. If all circuits test normal, replace the steering wheel position sensor.
