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

Direct Current/Alternating Current (DC/AC) Inverter – Overview
Function indicator
WARNING: For workshop repairs, it is only
permissible to replace the converter as a
complete unit together with the wiring
harness and the socket. The component
must not be opened, as charged capacitors
inside can still carry dangerously high
residual voltages.
The LED in the socket lights up orange when the
converter is supplying a voltage.
In the event of a fault the system switches off and
indicates the cause of the fault by flashing a trouble
code via the LED in the socket:
• 1x flash – High temperature
• 2x flashes – Overload
• 3x flashes – Internal overvoltage
• 4x flashes – Internal undervoltage
• Continuous flashing – Short circuit to power
If the converter switches off due to high
temperature then it switches back on again
automatically once the temperature has cooled
down sufficiently.
With all of the other faults which are displayed, the
converter can be reset by switching the ignition off
and back on again or by unplugging and reinserting
the consumer in the socket.
If these measures are unsuccessful then there are
no further options for directly influencing the
function yourself. G1055637en

Component Description
DC/AC converter
The converter operates with a series connection
of two power converter circuits. The primary power
converter here is a push-pull converter. It converts
the 12 V supply from the electrical system of the
vehicle to an intermediate direct current link of
approx. 320 V.
From this intermediate direct current link, the
downstream full H-bridge circuit generates a
pulse-width modulated output voltage with 230
V/50 Hz.
A controller modulates the pulse width of the
square-wave output voltage and maintains an
effective output voltage of 230 V under varying
load conditions and under different input voltages.
Here, the rising and falling edge of the positive and
negative square wave pulse are controlled
symmetrically to the ideal shape of a sine wave,
which - among other things - also makes a positive
contribution to electromagnetic compatibility.
DC/AC converters which supply a modified square
wave output voltage are referred to as 'Modified
Sine Wave Inverters".
With this type of system there is no need for a
residual current operated device for protection in
the event of accidental contact, as all of the 230 V
lines are double-insulated. Potential-free separation
of the entire 230 V voltage part from the vehicle is
provided (electrical isolation).
The output voltage of 230 V/50 Hz is not generated
until the switching voltage is present at terminal 1
of the converter via the AC mains outlet switch.
The converter operates with the ignition switched
on and a vehicle electrical supply of between 11
V and 16 V. Internal voltage monitoring in the converter deactivates the system if the input
voltage is outside this range.

In order to prevent accidents and the risk of
electrical shock, the outlet is protected with a child
safety device and the AC outlet switch.
In order to make the system safer for children, the
safety catches for the 230 V contacts can only be
pushed to one side by pressing a Euro plug evenly
into both of the connector openings.
The AC mains outlet switch only activates the
system when a consumer is connected to the
outlet. G1055639en
