F 250 2WD Super Duty V8-5.4L VIN 5 (2006)
H18-H19
Normal Operation
The high speed CAN has an unshielded twisted pair cable, circuits 1908 (WH) and 1909 (BK). The anti-lock brake system (ABS) module, the
instrument cluster, the powertrain control module (PCM) and the trailer brake controller are all on the CAN. The total resistance values from the
module to the data link connector (DLC) must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the CAN
circuits, damage to the DLC C251, damage to one of the communications network module connectors, or damage to an in-line connector.
