F 150 2WD Pickup V8-4.6L VIN W (2006)
L1-L4
Normal Operation
The diagnostic tool is connected to the data link connector (DLC) C251 to communicate with the controller area network (CAN), universal
asynchronous receiver transmitter (UART)-based protocol (UBP) communications network, and the international standards organization (ISO) 9141
communications network.
If communication cannot be established, the diagnostic tool and the DLC C251 must be checked for damage. If the diagnostic tool and the DLC C251
are OK check voltage circuit 40 (LB/WH), for an open or short to ground. Ground circuits 57 (BK) and 567 (LB/YE) must be checked for an open
condition.
