1997 MERCEDES-BENZ ML430 relay

GF72.29-P-2002GH
Convenience control, function
7.4.97

MODEL
163

The convenience control allows the driver to operate the electrical

seat adjustment, the power windows, the electric vent windows, the

electric outside rearview mirror as well as the electric sliding/pop-up

roof or the electric lamella sliding roof

when the ignition is switched

off.

To achieve this, the all-activity module (AAM) (N10) switches to the

corresponding loads via the convenience relay (F1k14)

circuit 30 .

As of 12.99 the vehicle is equipped with its own convenience relay for

seat adjustment (relay 1, F2k1). In addition the status of the

convenience control via CAN is transmitted to the extended activity

module (EAM, N10/1).

Conditions for control actuation

On all-activity module (AAM) (N10) configured for

I
up

to

11.99:

The convenience actuation becomes active as soon as

D
Circuit 15 ON is recognized

When circuit 15 is switched off, the convenience actuation is

deactivated after a door is opened
Otherwise

The convenience actuation is active in the following cases:
D
Circuit 15c ON

D
A front door is open

D
The remote control key is removed, however, the doors are not

yet opened

In both cases the convenience actuation remains active for 5 min.


Switch-on condition for circuit 15c

When the remote control key is inserted into the ignition lock, circuit

15c is switched on when the key is turned out of the zero position.

Circuit 15c switches off only after the remote control key is removed

from the ignition lock

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.

Task
After engine start speed is reached, interrupt the circuit (circuit 50) M1 to the solenoid switch of the starter.
Design
The solenoid switch of the starter is operated not through the ignition/ start switch S2/1, but in drive position P
or N through the starter relay, by the engine control unit.
The voltage for the starter relay (coil) is supplied through circuit 87. The starter relay is actuated by the engine
control unit through GND.
Function
When the ignition/start switch is operated in the start position, the engine control unit activates an automatic
start control. Once the engine start speed of 400 to 700 rpm is reached, the engine control unit interrupts the
ground actuation to the starter relay and thus the engine start operation.
Once the engine start operation is initiated, shutting off circuit 50 at the ignition/start switch has no effect. The
starter rotates until the specified start speed is reached, or for about 5 seconds at an engine temperature of +80 °
C, for a maximum of 10 seconds if the engine is cold.
