F 150 2WD Pickup V8-4.6L VIN W (2006)
The PCM communicates with the diagnostic tool through controller area network (CAN) circuits 1827 (WH/LG) and 1828 (PK/LG).
Check the CAN circuits between the PCM C175b and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms.
If the resistance is more than 5 ohms there is an open in circuit 1827 (WH/LG) and 1828 (PK/LG), damage to the DLC C251, damage to the PCM
C175b, or a problem with the in-line connector.
