Test Description

WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2. Tests for specified voltage on the yaw rate signal circuit.
  2. 3. Checks the voltage between the ignition and ground circuit for a specified value.
  3. 4. Checks the voltage between the ignition and ground circuit for a specified value.
  4. 5. Checks to see if voltage was above specified voltage.
  5. 6. Checks to see if voltage was below specified voltage.
  6. 7. Checks to see if EBCM 5 volt reference signal is within specified limit.
  7. 8. Checks to see if voltage was above specified voltage.
  8. 9. Checks to see if resistance of ground circuit is less than 5 ohms.
  9. 10. Tests for a short to voltage on the 5 volt reference circuit.
  10. 11. Tests for a short to ground, a high resistance, or an open in the 5 volt reference circuit.
  11. 12. Tests for a short to voltage in the yaw rate signal circuit.
  12. 13. Tests for a short to ground, a high resistance, or an open in the yaw rate signal circuit.
  13. 14. Tests for a high resistance or an open in the ground circuit.
  14. 15. Checks the EBCM connector for poor connections.
  15. 16. Checks the yaw/lateral accelerometer sensor connector for poor connections.
