Definitions


Definitions
These explanations refer only to this assembly: Brake system. These definitions are not necessarily valid generally.

ABS
The Anti-Lock Brake System (ABS) is a regulating system in the brake system which prevents the wheels from locking-up.

ASR (Anti-Slip Regulations)
Further information on the ASR can be found in the relevant self-study programs.

Sender for rotation rate -G202-
The sender for rotation rate recognizes the rotational movement of the vehicle along the vertical axis compared with the speed of the vehicle.

Sender 1 for brake booster/Sensor -2- for brake pressure -G201-/-G214-
Recognizes the pressure exerted by the driver and is required to control the pressure of the prepressure system.

Speed sensor
The speed sensor sends the speed signal to the control module.

ESP (Electronic Stabilization Program)
The ESP recognizes critical vehicle conditions and stabilizes the vehicle by braking individual wheels and intervening in the engine management system. This occurs independent of brake or accelerator pedal operations.
A description of the construction and function of the ESP can be found in the relevant self-study programs.

ESP-Sensor Unit -G419-, vehicles from my 02.02
The sensor for transverse acceleration -G200- the sender for rotation rate -G202- and the longitudinal acceleration sensor -G251- (4MOTION vehicles) are assembled together in a housing.

Steering angle sensor -G85-
Determines the angle and direction of steering lock (driver's wish). Data is transferred to control unit via data bus wiring.

Sensor for transverse acceleration -G200-
The lateral acceleration sender is used to register the speed through curves/bends in the road and decides which side of the vehicle the ESP is to brake.

EDL
Electronic Differential Lock. Further information on this can be found in the relevant self-study programs.
