ESP switch
E99006
Stability assist can be deactivated via the menu in
the instrument cluster. The stability assist functions
are deactivated when the Set switch is actuated.
The ABS control module makes the stability assist
functions available once more when the Set switch
is actuated again. The stability assist function is
automatically reactivated when the ignition is
switched on.
The electronic EBA is a constant function and will
remain active even if the ESP has been switched
off.
Combined yaw rate sensor and lateral
acceleration sensor / longitudinal
acceleration sensor
E96822
The heart of the combined yaw rate sensor and
lateral acceleration sensor/longitudinal acceleration
sensor is a small, double-sided tuning fork made
of a piezo crystal (A). The exciter side of this tuning
fork is set to a resonance of 11 kHz with the aid of
an alternating current. The measuring side of the
tuning fork features a resonance frequency of 11.33
kHz and therefore does not vibrate (B). Since,
under influence of an external accelerating force,
a vibrating mass reacts slower than a comparable
mass that is not vibrating, the tuning fork twists
within itself with rotational movement being
imparted on the sensor (C). This rotation results
in a change in the charge distribution in the Piezo
element, which is subsequently picked up and
converted into an electronic signal by electronics
integrated into the sensor. This electronic signal is
then sent to the ESP module. The ESP module
evaluates these data and takes into account the
other input data (vehicle speed, wheel speed)
before deciding whether the ESP function is
required.

Due to the special way in which it works. the
combined yaw rate sensor and lateral acceleration
sensor/longitudinal acceleration sensor must be
installed the right way up in the designated location
specified by the manufacturer. Any slight deviation
in the installation position and/or installation
location could lead to impaired functionality and
thereby possible failure of the stability assist.
Front wheel sensor
E96823
Active sensors are used to determine the rotational
speeds of the wheels at the hub. After the ignition
is switched on, the ABS module supplies the
sensors with power. The sensors work in
accordance with the Hall effect principle and

generate a square wave output signal. The signal
acts in proportion to the rotational speed of the
sensor ring. The ABS sensor rings are built into
the seals in the front wheel bearings. The ABS
module evaluates the signals from all four sensors
to calculate a vehicle speed signal based on the
rotational speeds of all wheels. The road speed is
transmitted on the CAN bus. The powertrain controlmodule (PCM) uses this signal and the
programmed tire size to calculate the vehicle
speed. The calculated vehicle speed is forwarded
on the CAN bus and is requested by other control
units that need this input information.
Rear wheel sensor
E96824
The sensors are joined to the main wiring harness
using a separate connecting cable.
