Circuit/System Verification

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: Ensure the transmission fluid is at the proper level by performing the Transmission Fluid Check .
  1. Ask about the customer driving habits, trailer towing, etc. Trailer towing should occur in D.
  2. Review the Failure Records when the DTC set. Verify the engine coolant temperature is less than 125°C (257°F).
  3. Ensure the engine cooling system is functioning normally/properly. The TFT on the scan tool should rise steadily to a normal operating temperature, and then stabilize.
  4. Inspect the transmission cooling system for restrictions or damage.
  5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
