TRW EBC 325 Controller Antilock Brake (Cab)
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The CAB is mounted directly to the hydraulic control unit (HCU) that includes a microprocessor and six solenoids that control valves that control brake pressure during antilock braking. The CAB also has circuits that monitor the following:
- Brake switch input is monitored to determine whether or not to prepare for possible ABS braking
- Monitor the brake fluid level switch input to tell whether or not the state of the hydraulics has a problem
- Wheel speed sensors are monitored to determine when a wheel is tending to lock up. The CAB will operate the valves in the HCU to control braking pressure during ABS braking
- Detect ABS system related problems and take diagnostic action
- Able to execute self-tests and output control commands
