2006 Buick Terraza CXL, 3.5 L, AWDSECTION Test Description
WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. 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:  This step tests for specified voltage on the 5-volt reference signal circuit.
  2. 3:  This step checks to see if voltage was below specified voltage.
  3. 4:  This step checks to see if voltage was above specified voltage.
  4. 5:  This step tests for a short to ground in the 5-volt reference circuit of the yaw/lateral accelerometer sensor.
  5. 6:  This step tests for a short to voltage in the 5-volt reference circuit of the yaw/lateral accelerometer sensor.
  6. 7:  This step tests for a high resistance or an open in the ground circuit of the yaw/lateral accelerometer sensor.
  7. 8:  This step checks the yaw/lateral accelerometer sensor connector for poor connections.
  8. 9:  This step checks the EBCM connector for poor connections.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
