Anti-Lock Brake System (ABS) Module
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module is on the high speed CAN. The ABS module controls the brake pressure to the 4 wheels to keep the vehicle under control while braking. If one of the bus wires becomes shorted to ground or voltage, communications can continue at a reduced level. Check the high speed CAN circuits 1908 (WH) and 1909 (BK), between the ABS module C155 and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the high speed CAN, damage to the DLC C251, damage to the ABS module C155, or a problem in the in-line connector.
