Electronic Brake Control Module: Description and Operation
Kelsey-Hayes EBC 325 Controller Antilock Brake (CAB)
The CAB is mounted directly to the hydraulic control unit and includes a microprocessor and six solenoids 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 antilock braking.
-
Wheel speed sensors are monitored to determine when a wheel is tending to lock up. The CAB will operate the valves in the ECU to control
braking pressure during antilock braking.
