The ABS monitors the different wheel speeds of
the vehicle with the aid of wheel speed sensors.
Using the data from all of the wheel speed sensors,
the ABS module calculates the so-called reference
speed, which is a measure of the actual road
speed. The ABS module compares the individual
circumferential wheel speeds with this reference
speed when the driver initiates braking. If one or
more of the circumferential wheel speeds deviates
too far from the reference speed, this means that
slip at the affected wheels is so great that steering
stability of the vehicle is no longer ensured. The
ABS module actuates electro-mechanical valves
which influence the brake pressure at the relevant
wheels.
Like the traction control system (TCS), the ESP
system uses a large proportion of the ABS
components. In addition, there are sensors which
pick up the steering angle, the acceleration forces
acting on the vehicle and the yaw rate or yaw
moment. The sensors transmit these signals to the
combined ABS/ESP module. Using the wheel
speed and steering angle data, the ABS/ESP
module calculates the direction of travel planned
by the driver and determines the corresponding
speed-dependent lateral acceleration and yaw
moment. These values are compared with those
actual measured. If the actual lateral acceleration
and the yaw moment deviate excessively from the
target values (unstable driving characteristics), the
ABS/ESP module actuates individual brakes
selectively via the HCU (hydraulic control unit). In
addition, the engine speed is reduced by
intervention in the engine management system.
How the system works for understeer: In the
event of understeer, brake intervention occurs at
the wheels on the inside of the curve. The rear
wheel is braked heavily, so that a high amount of slip is caused. In this way, the cornering force of
the rear axle is heavily reduced and the centrifugal
force that now becomes effective turns the rear of
the vehicle back into the curve. The front wheel is
not braked as hard. The braking force that is
transmitted via the front wheel to the road surface
generates a torque with the aid of the lever arm
(vertical tire force to the vehicle's centre of gravity),
which supports the yaw moment of the vehicle.
Both measures together result in the vehicle
reverting back to the curved path intended by the
driver.
How the system works for oversteer:
In the
event of oversteer the wheels on the outside of the
curve are braked. This time, the front wheel is
subjected to a high level of slip so that the
cornering force at the front axle is reduced. The
rear wheel is not braked as heavily and, together
with the effective lever arm, results in a reduction
in the vehicle yaw moment. Both measures
together result in the vehicle being stabilized and
reverting back to the curved path intended by the
driver.
If ESP control occurs, possible ABS interventions
will be overridden as the ESP works at higher slip
rates than the ABS.
Emergency brake assist (EBA): The emergency
brake assist helps drivers in emergency braking
situations by automatically applying the brakes with
the maximum possible braking force.
If the brake pedal is pressed very suddenly, the
ABS module increases the hydraulic pressure to
all of the brakes until the threshold for ABS
intervention is reached. This applies the maximum
braking effort for the available traction. The ABS
control unit monitors inputs from the brake pedal
switch and from the pressure sensor within the

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.

General EquipmentFeeler gauge
Straight edge
Items to be observed when checking the steering
system
The following list of steering gear conditions and
the methods of testing should be taken into account
when carrying out checks to the steering system:
• If the steering gear has no faults after completing the following checks, do not install
a new steering gear.
• Surface corrosion and marks on the tie-rod are acceptable.
• When checking for turning effort torque peaks in the steering gear, turn the steering wheel from
steering lock stop to steering lock stop in
approximately 15 seconds.
• A steady increase of turning effort torque from steering center to steering lock stop is
acceptable.
• When checking for power steering fluid leaks, turn the steering wheel to the steering lock stop
in approximately 10 seconds.
• Noises from the power steering, for example the power steering pump relief valve, are
acceptable.
STEERING GEAR HOUSING
1. Raise and support the vehicle. REFER to: Lifting(100-02 Jacking and Lifting,
Description and Operation).
2. Visually inspect the steering gear housing for cracks and damage. If the steering gear housing
is cracked or damaged, install a new steering
gear.
REFER to: Steering Gear (211-02 Power
Steering, Removal and Installation).
TIE-RODS
1. Using a straight edge and feeler gauge, check the tie-rods to see if they are straight. If the
distance between the tie-rod and straight edge is greater than 0.5 mm, install a new steering
gear.
REFER to:
Steering Gear (211-02 Power
