Navigator 4WD V8-5.4L VIN 5 (2006)
Normal Operation
The vehicle security module communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits 2180
(WH/BK) and 2181 (BK/YE). Check circuits 2180 (WH/BK) and 2181 (BK/YE) between the vehicle security module C2113c 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 one of the
medium speed CAN circuits, damage to the DLC C251, damage to the vehicle security module C2113c, or a problem in an in-line connector.
