Identification of System

System Coverage
There are two systems used on the Dodge Ram Van/Wagon (AB): Kelsey-Hayes EBC 2 and EBC 325 System. EBC 325 is a four wheel antilock braking system. EBC 2 is a rear wheel only antilock braking system.

IDENTIFICATION OF SYSTEM
Vehicles equipped with the EBC 2 system can be identified by the presence of a separate hydraulic control unit (HCU). The HCU is used to control hydraulic pressure to the REAR brakes during antilock braking. The HCU is controlled by a controller-antilock brake (CAB) mounted beside the HCU. The HCU and CAB are mounted on one bracket.

The EBC 325 system can be identified by the presence of the controller antilock brake (CAB) located directly on the HCU. This system uses one HCU to control the front and rear brakes. All of these components are mounted under the hood in close proximity to the master cylinder. The EBC 325 system will have a separate front wheel speed sensor wiring connector connected to the CAB.
