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.

General

The oil level is constantly monitored by the oil sensor, and the

appropriate data transmitted to the processor by the ASSYST.

Oil replenishments are detected automatically and result in a bonus,

which extends the service interval accordingly.

An excess oil level or insufficient oil level appears in the display

together with the oil can symbol.

Display of low oil level at maximum:
D
at driver request

Display of warnings: D
automatically, at the earliest 60 s after engine start and oil

temperature greater than 60°C:

D
if oil level too high: the oil can symbol appears together

with the readout "OIL LEVEL ABOVE MAX". In addition, a

brief warning signal sounds. (On models not fitted with

multifunction displaly, "HI" appears flashing.)

D
if oil level too low: the oil can symbol appears together with

the readout "OIL LEVEL BELOW MIN". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L" appears flashing.)

-----------------------------------------------------------------------------------------
D

if oil at minimum: the oil can symbol appears together with

the readout "OIL LEVEL MINIMUM". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on.)

D
automatically 13 s after ignition ON:

D
if
no oil
is in engine: the oil can symbol appears together

with the readout "OIL LEVEL BELOW MIN". In addition, a

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L"appears flashing. In addition a brief warning

signal sounds.)

The missing oil quantity displayed no longer changes during the

display. In other words, any change in oil level cannot be observed

directly at the display. The new oil level is only displayed once the

conditions described below exist.

Display of oil quantity at driver request

The text "DISPLAY OIL LEVEL?" appears 10 s after the start switch

has been turned into position "2" (on models not fitted with

multifunction display, the oil can and the clock symbol are displayed).

If the reset button of the trip counter is pressed twice within one sec.

during this readout, for example, "add 1.0L oil" (or "-1.0L")

-----------------------------------------------------------------------------------------

appears in the display if oil level too low. The readout appears only

after the elapse of a waiting time after engine OFF. The waiting time

depends on the engine oil temperature.

It is

D
up to 20°C
30 minutes

D
from 60°C
1 minute

D
The waiting time is between these two limits at other engine oil

temperatures.

Possible readouts are (text in parenthesis relates to models not fitted

with multifunction display.):
D
"OIL LEVEL OKAY" ("o.k."),

D
1.0L, 1.5L, 2L,

D
"Overfilling" ("HI"),

D
"OBSERVE WAITING TIME" (clock symbol flashing and oil can

symbol),

D
"DISPLAY OIL LEVEL" (clock and oil can symbols.)

If there is a fault at the oil sensor (oil level/temperature/quality, B40)

the oil can symbol and the text "OIL LEVEL SENSOR FAULTY"

appears only 30 s after the fault has occurred.

(On models not fitted with multifunction display, the oil level warning

lamp (A1e12) comes on accordingly.)

For diagnosis, read also the injection system control module (N3)

with the HHT. (The instrument cluster (A1) receives the sensor data

through the CAN from the injection system control module (N3)).

-----------------------------------------------------------------------------------------
Oil change

The ASSYST has to be reset each time the oil is changed. Resetting

ASSYST also resets the remaining time and the remaining distance.

Resetting can be performed at the instrument cluster or using the

HHT.

The following data are stored when the system is reset:

D
current kilometer reading rounded off to 100,

D
total oil replenishments in the last interval,

D
remaining distance,

D
remaining time,

D
product of the quality factors,

D
the data of the last 5 resettings in 5 data sets

These data can only be read with the HHT!

If the specified quantity of oil is not replenished when the oil is

changed, the (internal) start distance is reduced.

Detecting oil replenishments
D
With the
HHT
it is possible to retrieve the last 10 oil

replenishments and the corresponding kilometer readings of

the current interval.

D
In the normal case, detection of an oil replenishment is

displayed by the remaining distance in the instrument cluster

being extended
