Anti-Lock Brake System (ABS) Module
WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module is on the ISO 9141 communication network. The ABS module controls the brake pressure to the four wheels to keep the vehicle under control while braking. The ISO communication network will not function if the wire is shorted to ground or battery voltage. Check the network circuit between the ABS module C135 and the DLC C251. Total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the ISO network, damage to the DLC C251, damage to the ABS C135, or a problem in the in-line connector.
