Circuit/System Testing

WARNING: This page is about a different car, the 2008 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the yaw rate/lateral accelerometer sensor.
  2. Test for less than 5 ohms of resistance between the low reference circuit terminal 5 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, verify a test lamp illuminates between the ignition circuit terminal 3 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the EBCM.
  4. Ignition OFF, disconnect the harness connector at the steering angle sensor.
  5. Ignition ON, test for 0 volts between the CAN bus low circuit terminal 5 and ground at the steering angle sensor connector.
    • If greater than the specified value, test the CAN bus low circuit for a short to voltage.
  6. Test for 0 volts between the CAN bus high circuit terminal 2 and ground.
    • If greater than the specified value, test the CAN bus high circuit for a short to voltage.
  7. If all circuits test normal, replace the yaw rate/lateral sensor.
