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.

System Operation
Electronic principle of operation
The power steering module requires the following
information in order to ensure precise steering
behavior in all driving situations:
• Steering wheel position
• Rate of turn of the steering wheel
• Vehicle speed
• Information about the vehicle configuration
• Information about the ignition switch position
• Instantaneous engine operating status
The required information is made available to the
power steering module via direct connections and
via the CAN bus (refer to the flow chart).
The steering wheel position and the rate of turn of
the steering wheel are transmitted to the power
steering module as PWM signals from the steering
angle sensor. The steering angle sensor receives
its voltage and ground supply from the power
steering module and operates inductively with an
input voltage of 5 V.
The vehicle speed is made available to the power
steering module as a CAN bus signal from the ABS
module or ESP module. The engine operating status is made available to
the power steering module as a CAN bus signal
from the PCM.
The power steering module obtains the vehicle
configuration information via the CAN bus from the
GEM. This information is required by the power
steering module in order to define the internal
characteristics of the power steering.
The power steering module obtains information
about the current ignition switch position via the
voltage input (terminal 15) of the ignition switch.
Whilst constantly monitoring the relevant input
signals the power steering module accesses stored
maps. With the aid of this information the pump
speed is matched to the current driving situation.
An electronic diagnosis of the electro-hydraulic
power steering can be performed with the aid of a
diagnostic tester via the DLC of the vehicle. For
additional information please refer to "Diagnosis
and Testing" in this section.

System Operation
Smart Start
The PCM enables the starting process when a key
providing a valid code is read via the PATS. This
code is then verified in the GEM and compared
with the saved code. If this code is recognized as
correct, synchronization with other modules is
carried out. After successful synchronization, the
engine is cleared to start in the PCM. The PCM
connects earth to the starter relay, which then
connects power to the starter solenoid. As soon
as the engine reaches a certain speed, the PCM
disconnects the starter relay and so turns off the
starter. This protects the starter.
If the engine does not turn or turns only slowly, the
starting process is aborted by the PCM.
The starter is notactivated if:
• the engine is running (i.e. the engine speed is above a particular value),
• the PATS does not permit the engine to be started,
• the clutch pedal is not operated (vehicles with manual transmission),
• the gear selector level is not set to P or N (vehicles with automatic transmission),
• the brake pedal is not operated (vehicles with automatic transmission).
Emergency starting function
If the keyless vehicle system is unable to recognize
the passive key, the vehicle can be started via the
emergency starting function. In this case, there is a passive key mount on the
steering wheel. A PATS transmission/reception
unit is attached to this.
To start the engine, the passive key must be
inserted into the passive key mount. The Start/Stop
button can then be used to turn on the ignition and
start the engine as normal. To deactivate the
PATS, a transponder is fitted in the passive key,
which is read by the transmission/reception unit.

Powertrain Control Module (PCM)
E65160
The PCM communicates with all engine sensors
and the other modules. Communication of the PCM
with the other modules and the system diagnostics
takes place via the CAN (controller area network)
data bus.
The following functions are regulated or controlled
by the PCM:
• Fuel supply to the engine including lambdacontrol
• Ignition setting including knock control
• Idle speed control
• Control of optimum valve timing via the camshaft adjustment for intake and exhaust camshafts
• The refrigerant compressor is controlled by the air conditioning clutch relay and the delivery of
the refrigerant compressor is controlled by a
PWM (pulse width modulation) signal.
• Control of EVAP purge valve
• Boost pressure control
• Control of the cooling fan
• Charging system (Smart Charge)
• Starting system (Smart Start)
If the PCM is isolated from the vehicle electrical
system or the battery is disconnected, the throttle
control unit mustbe initialized.
The PCM is fitted in the engine compartment in the
air filter housing. On right hand drive vehicles a
protective metal plate is also installed to prevent
the plug connector from being pulled off, or make
it harder to pull off, in case of theft. The protective
plate is secured with a shear bolt. The shear bolt
needs to be drilled out in order to remove the
protective plate.
Knock Sensor
E96986
Two KSs are fitted. They are on the cylinder block,
one close to the 2nd cylinder and one close to the
4th cylinder.
When fitting, adhere strictly to the specified
tightening torque, otherwise the KS will not work
properly.
If the signal from one or both KS is implausible or
absent, knock control is deactivated. The PCM
switches to an ignition map that is further away
from the knock limit. As a result, engine damage
caused by combustion knock is avoided. If a fault
occurs, a fault code is stored in the error memory
of the PCM.
Camshaft Position (CMP) Sensor
E89993
If one or both CMP sensors fail, a fault is saved in
the error memory of the PCM and the camshaft
adjustment and knock control are deactivated.

If one of the two APP sensors fails, then only a
proportion of the engine's power will be available
when accelerating. Top speed can nevertheless
be achieved.
If both of the APP sensors fail, the engine is
regulated to a defined speed following a plausibility
check after the BPP (brake pedal position) switch
and brake light switch have been actuated once.
The vehicle can then only be accelerated to a
defined speed.
In either case, a fault is saved in the error memory
of the PCM.

After disconnecting the battery or replacing the
throttle control unit or the PCM, initialization is
necessary. • engine off

• Wait approximately 30 seconds until initialization
is complete.
Engine Coolant Temperature (ECT)
sensor
E94804
The ECT (engine coolant temperature) sensor is
designed as an NTC (negative temperature
coefficient) resistor.
If the signal from the ECT sensor fails, the cooling
fan is on all the time and the A/C (air conditioning)
is turned off. When the ignition is switched on, the
value from the IAT (intake air temperature) sensor
is read. When the engine is running, the
temperature is calculated using a temperature map
stored in the PCM according to how long the
engine has been running. This substitute value is
then used as the basis for calculating the injected
fuel quantity and the ignition timing.
