DTC Chart: Powertrain Control Module (PCM)
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these 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.
