Climate Control System DTCS
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
NOTE:
Network communication or missing message Diagnostic Trouble Codes (DTCs) may result from intermittent concerns, such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures may set these DTCs. To avoid repeat network concerns, follow all Service Information guidance for the code. Test the vehicle battery.
NOTE:
Some Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs) may inhibit Air Conditioning (A/C) operation. If any Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs) are retrieved, diagnose those first. Refer to the Master Diagnostic Trouble Code (DTC) Chart.
