Electronic Automatic Temperature Control (EATC) Module Diagnostic Trouble Code (DTC) Index
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
All DTCs can be retrieved as an on-demand (hard fault) or continuous (intermittent fault) fault. If a continuous (intermittent) fault, the degrees Celsius symbol (°C) will be displayed in addition to the DTCs.
