Scan Tool Data List

2008 Pontiac Grand Prix BaseSECTION Scan Tool Data List
WARNING: This page is about a different car, the 2007 Buick LaCrosse and 2007 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

Use the Scan Tool Data Display Values and Definitions Information in order to assist in diagnosing the HVAC system. Compare the vehicles actual scan tool data with the typical data display value table information. Use the data information in order to aid in understanding the nature of the problem when the vehicle does not match with the typical data display values.

The scan tool data values were taken from a known good vehicle under the following conditions:

  • The ignition switch is in the ON position.
  • The engine is running at idle.
  • The vehicle is in PARK.
  • The doors are closed.
  • The windows are closed.
  • The A/C is ON.
  • The ambient air temperatures are at 22-27°C (70-80°F).
