Diagnostic Trouble Code Tests and Associated Procedures

HVAC MODULE - ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC) DTC CHART

NOTE:
- Some PCM DTCs may inhibit A/C operation. If any PCM DTCs are retrieved, diagnose those first. Refer to Computers and Control Systems.
- 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.
