Normal Operation

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The ABS module communicates with the diagnostic tool through the controller area network (CAN), circuits 1908 (WH) and 1909 (BK). Check circuits 1908 (WH) and 1909 (BK) between the ABS module C135 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 CAN circuits, damage to the DLC C251, damage to the ABS module C135, or a problem in an in-line connector.
