WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that no other DTCs are set.
  2. Clear the DTCs.
  3. Operate the vehicle according to the Driving Conditions 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.
  4. After the Driving Conditions have been met, drive the vehicle at approximately 80 km/h (50 mph) for 60 seconds.
  5. Perform a closed throttle deceleration until the vehicle speed is less then 40 km/h (25 mph).
  6. Verify that DTC P0420 has passed this ignition cycle.
    • If not passed or failed this ignition cycle, the test aborted resulting in an inconclusive test result. The above test may need to be repeated up to 5 more times during this drive cycle.
