ger footwell and another on the right-hand
side of the luggage compartment.
Flip up cover and insert electrical plug
(cigarette lighter type).
Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center
for information on the installation of an ap-
proved external antenna. Refer to the radio
transmitter operation instructions regard-
ing use of an external antenna.
iThe outlets function even if the key is
not in the ignition.
The electrical outlet can be used to
accommodate electrical consumers
(e.g. air pump, auxiliary lamps) up to a
maximum of 180 W.
If the engine is off, the battery may be-
come discharged if used for long peri-
ods of time.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and / or serious
personal injury.

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.

REST BUTTON, FUNCTION - GF83.40-P-2109-01GI
Function
Pressing the reset button ( ) on the AAC push-button control module (N22) switches on the residual engine
heat utilization system. When the engine is switched off, the residual heat heats the vehicle depending on the
temperature setting on the AAC push-button control panel (N22) and the ambient temperature in the vehicle
interior. The vehicle can be heated for approx. 30 min, with the engine switched off. The function is only
available with the ignition switched off or in position 1. If there is low voltage, the residual heat function is
automatically switched off.
The flaps are in automatic mode and the quantity of air is also automatically regulated.
The residual heat function is switched off,
if the electronic key is moved to position 2 in the starter switch,
after approx. 30 minutes,
if the battery voltage drops below 11V.
AUXILIARY FAN, FUNCTION - GF83.40-P-2115-01GH
Function
Depending on the refrigerant pressure and/or the coolant temperature the left auxiliary fan (M4m1), right
auxiliary fan (M4m2) are actuated.
The all-activity module (AAM) (N10) receives the coolant temperature from the coolant temperature sensor and
the refrigerant pressure from the refrigerant pressure sensor (B12).
The all-activity module (AAM) (N10) compares this input information with stored values and actuates the left
auxiliary fan (M4m1), right auxiliary fan (M4m2).
When the following values are indicated the left auxiliary fan (M4m1), right auxiliary fan (M4m2) are switched
on or off:
refrigerant pressure >16 bar = auxiliary fan ON
refrigerant pressure < 12 bar = auxiliary fan OFF
coolant temperature > 105°C = auxiliary fan ON
coolant temperature < 94°C = auxiliary fan OFF
