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.

current value is reached. The PCM then
permanently connects the heating element to earth.
The catalyst monitor sensor is used by the PCM
to measure the oxygen content in the exhaust gas
in the TWC. If all the conditions for catalyst
diagnostics are met, based on this information the
PCM can check that the TWC is working
satisfactorily. The information is also used to
improve the air/fuel mixture adjustment.
The catalyst monitor sensor is similar in function
to an HO2S. The signal transmitted by the catalyst
monitor sensor changes sharply if the oxygen
content in the exhaust gas changes. For this
reason, catalyst monitor sensors are also called
"jump lambda sensors".
Fuel tank purging
The EVAP purge valve is only actuated by the PCM
if the coolant temperature is at least 60°C.
Actuation is done ground side by means of a PWM
signal. This makes it possible to have the full range
of opening widths, from fully closed to fully open.
The PCM determines from the operating conditions
when and how wide to open the EVAP tank purge
valve. If the EVAP purge valve is opened, the
engine sucks in ambient air through the activated
charcoal in the evaporative emission canister as
a result of the vacuum in the intake manifold. In
this way the adsorbed hydrocarbons are led to the
combustion chamber of the engine.
The EVAP tank purge valve is not actuated and
system cleaning is interrupted if the engine
switches to idle and/or a closed-loop control
process is initiated.
Power (battery voltage) is supplied via the
Powertrain Control Module relay in the BJB. The
solenoid coil resistance is between 17 and 24 ohms
at 20°C.
Engine speed control
The APP sensor provides the PCM with information
about the driver's request for acceleration.
The throttle control unit receives a corresponding
input signal from the PCM. An electric motor then
moves the throttle valve shaft by means of a set
of gears. The position of the throttle is continuously
recorded by the TP sensor. Information on throttle
position is processed and monitored by the PCM.
The TP sensor comprises two potentiometers.
These work in opposite ways to each other. In one
potentiometer, the resistance increases when the
throttle is opened, in the other it decreases. Thisallows the operation of the potentiometers to be
checked. The signal from the TP sensor is
amplified in the lower range (idle to a quarter open)
by the PCM to enable more precise control of the
throttle in this range. This is necessary because
the engine is very sensitive to changes in throttle
angle in this throttle opening range.
With the throttle valve position kept constant, the
ignition angle and the injected fuel quantity are
then varied to meet the torque demands.
Depending on the operating state of the engine, a
change in the position of the throttle flap may not
be necessary when the APP sensor changes.
If a fault develops in the throttle control unit, a
standby function is executed. This standby function
allows a slight opening of the throttle flap, so that
enough air passes through to allow limited engine
operation. For this purpose, there is a throttle flap
adjustment screw on the throttle housing. The
return spring closes the throttle flap until the stop
of the toothed segment touches the stop screw. In
this way a defined throttle flap gap is formed for
limp home mode.
The stop screw has a spring loaded pin, which
holds the throttle flap open for limp home mode.
In normal operating mode, this spring loaded pin
is pushed in by the force of the electric motor when
the throttle flap must be closed past the limp home
position (e.g. for idle speed control or overrun
shutoff).
Oil monitoring
The engine does not have an oil pressure
switch.
The oil level and oil quality are calculated.
Calculating the engine oil level
The oil level is determined by continuous
measurement of the capacitance (i.e. the ability to
store an electrical charge) between the two
capacitive elements of the engine oil
level/temperature/quality sensor. The different oil
levels cause the capacitance between the elements
to change. The data are recorded by the PCM and
converted into an oil level value. Temporary
fluctuations in oil level are automatically filtered out
by the PCM.
Calculating oil quality
The PCM calculates the oil quality from the oil level
measurement and the oil temperature measured
by the sensor, plus the engine speed and the
average fuel consumption. The driver is informed
about when an oil change is due.

Changing the right-hand fuel pump and level
indicator module
E113328
If the right-hand fuel pump and level indicator
module needs to be changed on a vehicle with a
booster heater/additional heater, the bore for the
connection to the fuel-fired booster
heater/additional heater must be drilled.
The right-hand fuel pump and level indicator
module contains a demand-switched electric fuel
pump which drives two suction jet pumps. One of
them ensures that fuel is pumped from the left-hand
half of the tank into the right-hand half. On-demand
switching is performed by the fuel pump module.
To remove the right-hand fuel pump and level
indicator module it is necessary to detach theleft-hand fuel pump and level indicator module and
pull it out slightly so that the connecting hose can
be detached and the connector for the left-hand
fuel pump and level indicator module can be
disconnected. The left-hand fuel pump and level
indicator module can be removed without detaching
the right-hand fuel pump and level indicator
module.
The instrument cluster uses the signals from both
fuel fill level sensors to determine the fuel fill level.
The resistor tracks of the fuel fill level sensors
cannot be replaced individually.
The fuel filter is designed to last for the service life
of the vehicle and does not need to be replaced.
The right-hand fuel pump and level indicator
module contains an overpressure limiting valve.
This overpressure limiting valve ensures that the
fuel pressure between the injectors and the
right-hand fuel pump and level indicator module
does not exceed 3.3 bar after the engine is
stopped. This reduces the formation of vapor
bubbles and also prevents dripping from the
injectors.
Fuel filler pipe and tank cap
NOTE:
Any water in the filling area can cause the
mechanism to freeze at temperatures below 0 °C.
In this case the closing mechanism will not open
when the nozzle of the petrol/diesel pump is
inserted.
