Circuit/System Testing

WARNING: This page is about a different car, the 2008 Cadillac STS. 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 between the ground circuit terminal 6 and ground.
    • If greater than the specified range, test for an open/high resistance in the ground circuit.
  3. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
  4. Ignition OFF, disconnect the harness connector X3 at the Supervisory Control Module.
  5. Ignition ON, test for 0 volts between the communication circuit terminal 72 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 52 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 72 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 52 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 72 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 52 and terminal 1.
    • If greater than the specified range, test the communication circuit for an open/high resistance.
  11. Test for infinite resistance between the communication circuit 72 and the communication circuit 52.
    • If not the specified value, test the communication circuits for a short together.
  12. If all circuits test normal, replace the steering angle sensor.
