Diagnostics assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to Diagnostic Methods Fundamentals and Basics for information regarding Ford-specific diagnostic practices.

NOTE: Network DTCs (Diagnostic Trouble Codes) (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 DTCs (Diagnostic Trouble Codes). Replacing a module to resolve a network DTC (Diagnostic Trouble Code) is unlikely to resolve the concern. To prevent repeat network DTC (Diagnostic Trouble Code) concerns, inspect all network wiring, especially connectors. Test the vehicle battery. REFER to Diagnostic Routine A: Battery Condition Test Pinpoint Tests.
