1997 MERCEDES-BENZ ML350 rear view mirror

GF54.21-P-4106-01GH
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.

AUTOMATIC DIMMING INSIDE REARVIEW MIRROR, FUNCTION - GF68.49-P-0003GH
MODEL 163 as of 1.9.99 with CODE (249b) Automatic dimming inside rearview and outside rearview
mirror (driver)
Function requirements
No overvoltage or undervoltage
Term. 15R or 15 ON
Reverse gear not engaged
Interior lighting not switched on
Function
The glass of the inside rearview mirror (A67) can be electro-chromatically dimmed. The mirror glass between
the reflector and the glass cover contains a layer of electrolyte gel. The light transmission ratio of this gel
changes when a voltage is applied to it.
The light hitting the surface of the mirror is more or less reflected due to the variable of the actuation voltage.
The actuation voltage is controlled by the electronic circuitry in the inside rearview mirror. This is
accomplished depending on the ambient light and the light hitting the mirror.
The two input parameters are detected by the mirror dimming to rear sensor (A67h2) in the mirror housing
(rear) and by the mirror dimming forward sensor (A67h1) in the mirror glass of the inside rearview mirror
(A67).
The inside rearview mirror unit (A67) also acts as the master for the outside mirror dimming function
(driver's side).

Program compatibility tester
1. Connect compatibility tester to cigar lighter.
2. Switch on circuit 15R or circuit 15.
3. Press one of the transmit buttons for longer than 20 s.
The compatibility changes over to the learning mode indicated by the LED flashing.
4. Hold the hand transmitter for the appropriate system against the interior rearview mirror and operate.
When the learning procedure is completed the LED flashes rapidly.
It is possible to program three different transmitter frequencies. A transmitter frequency is assigned to
each transmit button.
Open or close garage door
5. Press corresponding button. The signal learned for this memory location is transmitted.
The signal from the compatibility tester has a range of at least 85% of the range of the garage door
remote control, however at least 15 m.
If the garage door can be opened or closed, the garage door opener is compatible with the garage door.
Delete compatibility tester
6. Press the two outer transmit buttons for longer than 20 s. After approx. 10 s, the LED flashes rapidly to
indicate that all memory locations have been erased.
Before returning the compatibility tester, ensure that the programming is deleted!
