Fig. 68: Identifying Rear Window Antennas Design
The individual antennas are attached to the inner side of the rear window.
The AM antenna in some cases is part of the heating elements of the rear window defroster. The AM signals
are decoupled by the radio antenna splitter (A2/5) .
All the antennas are matched in terms of their length and shape to the particular frequency band which they
receive.
REAR WINDOW ANTENNAS, FUNCTION - GF82.62-P-3106-04GH
Model 163
Function:
The radio signals are received by the rear window antenna (A2/32) (AM, FM ). The high-frequency
oscillations (RF) of the electrical field in the air are converted into an electrical alternating voltage .
A standing electrical wave is formed in the antenna as a result of the correct matching of the length of the
antenna to the wavelength of the frequency to be received.
In this case, the amplitude of the RF signal has a constant value at a random point of the antenna. The RF
signal level is at the maximum at the connection point. A variation of the length of the antenna from its
optimum length results in a reduction in the RF signal level at the antenna output. If the variation is too large,
no further signal is received (for example if the antennas are incorrectly connected to the antenna amplifier).

Modification notes
Damage codeCauseRemedy
Under unfavorable
reception conditions in
FM-RDS mode, the radio
may frequently switch to
alternative frequencies of
one and the same radio
station. Due to the equipment
and antenna design there
is no remedy available.
During switchover,
reception may be
interrupted for a brief
period.Do not replace any radios
subject to this complaint
only!
11.2.00Supersedes STIP 82.60-
030 dated 10.2.00
Damage codeCauseRemedy
Complaint is caused by
retrofitting metallized
window foils. When installing
window foils, cut foil
outside of vehicle to
avoid damaging the
antennas and heating
wires
Metallized foil:
AM reception
reduced approx. 70
%, among other
problems search

Extended Activity Module - Task
n
The primary tasks of the Extended Activity Module (EAM, N10/1) are
as follows:
D
To control the door sill lights
D
To suppress the auto-dimming mirror function
D
To control the headlight cleaning system (HCS)
D
To control the rear window defroster
D
To control seat heating
D
To control the power supply via control console to tilt/sliding or
louvered sunroof switch
D
To control the PTC heater booster (R22/3)
D
To control the auxiliary fan (M4)
D
To read the cruise control switch (S40) and relay data to control
module (DAS, N73/1)
D
To read the contacts for wiper speed settings 1 and 2 on
combination switch (S4) for diagnosis.
To perform these tasks the Extended Activity Module (EAM, N10/1)
reads various signals and switch settings directly.
The Extended Activity Module (EAM, N10/1) interfaces with other
control modules via the engine compartment CAN.
-----------------------------------------------------------------------------------------
Diagnosis
Diagnosis is performed using the Star diagnostic tool. To facilitate
this task, the Extended Activity Module (EAM, N10/1) is equipped
with its own diagnostics cable.
This cable is also used to diagnose the
All Activity Module (AAM,
N10)
and the
transfer case control module (N78)
.
The Extended Activity Module (EAM, N10/1) is linked to the All
Activity Module (AAM, N10) via the
engine compartment CAN
.
Data communication between the All Activity Module (AAM,
N10) and the Extended Activity Module (EAM, N10/1) is
assumed by the
CAN (N10 - N10/1)
when terminal 15 is off.
The CAN (N10 - N10/1)
is an independent CAN bus located
between the All Activity Module (AAM, N10) and the Extended
Activity Module (EAM, N10/1).
No other
control modules are
connected to the CAN (N10 - N10/1).
-----------------------------------------------------------------------------------------
Details:
Door sill lights
When the front interior light is on and one of the front doors is open,
or when the rear interior light is on and one of the back doors is open,
the door sill lights for the open door will illuminate.
Headlight cleaning system (HCS)
Activating a separate switch causes the EAM to send a turn-on signal
to the HCS pump relay.
EAM will send an additional turn-on signal to the HCS pump relay
only after the cleaning operation is completed and a "rest period" of
approximately 2.5 sec. has passed.
Auto-dimming mirror function
The auto-dimming mirror function is suppressed when the interior
light is on or reverse gear is engaged.
Auto-dimming suppression for the outside rearview mirror (slave) is
activated by the inside rearview mirror (master).
Heater booster/PTC air heater for diesel engines
EAM monitors system voltage and adjusts heater booster capacity to
minimize load on battery.
Rear window defroster
EAM sets maximum ON time for rear window defroster depending
on outdoor temperature and current vehicle speed.
D
Standard ON time:
10 min.
D
Outdoor temperature < 5
o
C:
Additional 5 min.
D
Speed >80 km/h:
Additional 3 min.
Seat heating
Sets maximum seat heating time.
D
Setting 1: max. 20 min.
D
Setting 2: max. 5 min.
Tilt/sliding or louvered sunroofs
Signal via AAM2 allows operation of tilt/sliding or louvered sunroofs
when ignition is on (standard mode) or off (keyless mode).
Ignition authorization via CAN
The EAM issues ignition authorization to AAM2 via the engine
compartment CAN depending on the requirements of the engine
control unit in connection with the FBM.

Crankshaft position sensor

Intake air temperature sensor/charge air.
Coil ignition: The ME control unit interrupts at the point of ignition timing at the ground end the ignition
coil primary circuit of the ignition coil.
ECI ignition system (engine 137): The ME control unit actuates the output stages in the ECI ignition
modules.
The ignition angle can only be checked with the HHT/STAR DIAGNOSIS.
2.Ignition angle adaptation
2.1 Catalytic converter heating-up (warming-up)
The ignition angle is continuously retarded for about 20 seconds in order to more rapidly warm up the catalytic
converter to its operating temperature if:
coolant temperature at start > 15 °C and < 40 °C
Selector lever position P or N
At the same time idle speed is increased by the idle speed control.
2.2 Idle speed
To assist the idle speed control, the ignition angle can be retarded by as much as 36° crank angle or advanced by
as much as 20° crank angle.
Altering the ignition angle provides a more rapid control than altering the position of the throttle valve (idle
speed control).
2.3 Deceleration fuel shutoff
The ignition angle is briefly retarded when combustion is resumed (fuel injectors actuated) in order to prevent a
sudden increase in torque.
2.4 Intake air temperature/coolant temperature
The ignition angle is retarded under load, as a function of the intake air temperature and coolant temperature, in
order to prevent an
y knocking tendency at high intake air and coolant temperatures. The ignition angle is
