Electronic Brake Control Module: Description and Operation






System Control
^ The ABS control module detects wheel speeds and evaluates the situation of the wheels based on the signals from the speed sensors.
^ Based on the program within the control module, the control module then relays signals to the solenoid valves and the pump motor within the hydraulic unit to control wheel lock-up.
