ESP
Electronic Stabilization program

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

No communication
There is no connection for exchanging
information between the control modules.

Sender for rotation rate -G202-
Recognizes the rotational movement of the
vehicle along its vertical axis in relation to
vehicle speed.

Longitudinal acceleration sensor -G251-
Determines the correct speed for 4MOTION
vehicles

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

Short to Ground
Current flows incorrectly to Ground without
supplying a consumer.

Short to positive
Current flows incorrectly to a live component
without supplying a consumer.

Brake pressure release solenoid -F84-
The trip switch is installed in the brake booster
and is required by the control module to
recognize the braking desired by the driver.

Magnetic coil for brake pressure, in brake
booster, -N247-
The brake pressure solenoid is installed in the
brake booster and ensures that a pre-pressure
of 10 bar is available for the ABS/ESP pump.

Read measured value block
The control module can transfer a considerable
amount of test data. This test data delivers
information on the operational condition of the
system and/or sensors connected to it. In many
cases the transferred test data supports
troubleshooting and malfunction repair. The
test data has been summarized into single
display groups because all the information
cannot be evaluated at the same time. The
information can be selected via display group
numbers.
