ANTI-LOCK BRAKING SYSTEM
Fault finding - Function
EBD (electronic braking distribution):
The EBD optimises the brakeforce distribution between the front and rear axles. This function ensures vehicle
stability under braking.
ABS (anti-lock braking system):
The ABS prevents the wheels from locking when braking. This function allows the vehicle to be steered under
braking and ensures vehicle stability under braking.
MSR (engine torque control):
This is a function that enhances the ABS function. It prevents the drive wheels from spinning excessively when lifting
off the accelerator or changing down a gear on a low grip surface, by allowing the engine to regulate the driving
torque of the engine (resisting torque compensation) to "relaunch" the wheels.
The system also supplies the other computers with information on the vehicle speed via a wire connection for the
radio, the power steering and the electric sunroof, and via the multiplex network for the other computers. The ABS
computer supplies the multiplex network with the odometry for the instrument panel and navigation system. If heavy
braking produces very rapid deceleration, the ABS computer sends out a request to the UCH (passenger
compartment connection unit) via the multiplex network to ask it to switch on the hazard warning lights (depending
on the law in the relevant country).
