Generator
General information
The powertrain control module (PCM) controls the
alternator charging voltage. The connection
between the PCM and the generator is made via
the control module subnetwork (LIN) bus.
If the load on the alternator is high, the PCM can
increase the idle speed.
The alternator is temporarily deactivated during
engine starting so that the engine drag moment is
minimized and it is reactivated again after the
starting procedure.
The PCM controls the charge control lamp in the
instrument cluster via the controller area network
(CAN) bus.
Smart Charge system
In addition to the familiar functions, the Smart
Charge system also performs the following
functions:
•
Automatic deactivation of non-critical high power
electrical consumers when the battery voltage
is low in order to reduce the level of current
drawn.
• Automatic activation of non-critical high power electrical consumers when the battery voltage
is excessively high in order to protect
components which are sensitive to increased
voltages.
The battery charging current is optimized through
continuous calculation of the battery temperature
and monitoring of the alternator output voltage.
By receiving the forwarded alternator load signal,
the PCM is given early warning whenever an
electric consumer is switched on or off. This means
that the PCM receives information about imminent
changes in the torque drawn by the alternator. By
evaluating this information the PCM can provide a
higher level of idling stability.
The two remaining functions of the Smart Charge
System are controlled by the GEM.
Electrical consumers are switched off due to low
voltage when the GEM determines (on the basis
of the message received from the PCM on the CAN
bus via the instrument cluster) that the battery
voltage has dropped below the threshold.
When the threshold for low battery voltage is
reached the GEM automatically deactivates the following consumers - in this order and with a gap
of 5 seconds between each:
• Electric booster heater (vehicles with diesel
engines)
• Heated exterior mirrors
• Heated rear window
• Heated windscreen
If the battery voltage rises back above the lower
threshold then the GEM re-enables all of the
electrical consumers which were previously
disabled. They then have switched off status and
must be switched back on by the driver.
Electrical consumers are switched on due to
excessively high voltage if the GEM determines
that the battery voltage is above the threshold for
overvoltage and the charge control lamp has been
switched on.
When the threshold is reached the GEM
automatically activates the following consumers -
in this order and with a gap of 5 seconds between
each:
• Heated rear window
• Heated exterior mirrors
• Electric booster heater (vehicles with diesel engines)
• Blower motor
If the battery voltage drops back below the
threshold then the GEM automatically deactivates
any consumers that were switched on. However,
if they were switched on by the driver before the
automatic activation, they will then be switched on
again in turn with a 5-second time interval. G964174en

In an ignition system with coil-on-plug ignition coils,
each cylinder is actuated individually and only once
per cycle (working stroke). The coil-on-plug ignition
coils are mounted directly on the spark plugs,
therefore no ignition cables are required between
the ignition coils and the spark plugs.
Each individual ignition coil is actuated on the
low-voltage side by the PCM. The power
end-stages are incorporated into the coil-on-plug
ignition coils. Only the actuating current for these
power end-stages is controlled by the PCM.
Fuel pressure/fuel temperature sensor
E73531
The fuel pressure/fuel temperature sensor is a
combination of two sensors, one for the fuel
absolute pressure and one for the fuel temperature.
The sensors register the fuel values in the fuel
injection supply manifold. The sensor is supplied
with a 5V voltage by the PCM.
The fuel pressure sensor is a piezoresistor and
works using an analog signal. The change in output
voltage mirrors the change in pressure in the fuel
rail. If the pressure is low, the output voltage is also
low.
The fuel temperature sensor is an NTC resistor.
When the fuel pressure/fuel temperature sensor is
disconnected, the resistance of the fuel
temperature sensor between connections 1 and 2
of the sensor can be measured.

The values of the fuel pressure/fuel temperature
sensor can be read out with IDS. The displayed
values are absolute values (fuel pressure +
atmospheric pressure).
Wastegate control valve
E73539
The boost control solenoid valve is a 2/3-way valve
that is actuated with a PWM signal. This allows the
valve opening to be steplessly adjusted.
Power (battery voltage) is supplied via the
Powertrain Control Module relay in the BJB. The
solenoid coil resistance is around 23 ohms at 20°
C.
