E 150 V8-4.6L SOHC VIN W (2004)
Anti-Lock Brake System (ABS) Module
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.
Vehicle Security Module
The vehicle security module is on the ISO 9141 network. The vehicle security module controls the remote keyless entry (RKE) function as well as the
power door locks. The ISO communication network will not function if the wire is shorted to ground or battery voltage. Check the network circuit
between the vehicle security module C203b 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 vehicle security module C203b, or a problem in the in-line
connector.
