Electronic Brake Control Module: Description and Operation

Control Module:

The control module computes the speed, acceleration and deceleration of the wheels in response to the sensor signals.

The module features an built-in monitoring circuit which can detect internal module faults, as well as electrical faults in the sensors, hydraulic modulator, signal circuits etc.

A new control module with a function known as GMA is installed in models from 1990 on. Operating on the front wheels, GMA is active only when braking under ABS control. The function is engaged if a yawing movement occurs between the left and right-hand wheel pairs when running on different types of road surface (such as ice and bare earth).
