DTC Chart: Heating Ventilation Air Conditioning (HVAC) Module - Electronic Manual Temperature Control (EMTC)
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to : Diagnostic Methods .
Network Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming, often set network Diagnostic Trouble Codes (DTCs). Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery. Refer to : Battery .
NOTE:
Some PCM Diagnostic Trouble Codes (DTCs) may inhibit A/C operation. If any PCM Diagnostic Trouble Codes (DTCs) are retrieved, diagnose those first. Refer to DTC Chart: Powertrain Control Module (PCM) .
