Display
Function
Turn signal indicator
ticking
Switching on the turn signal indicator is
indicated acoustically by the turn signal
indicator ticking. The driver's attention is
brought to a defect in the turn signal system
by the turn signal indicator ticking at a higher
frequency.
Turn signal indicator ticking is generated
electromagnetically. The frequency
corresponds to that of the turn signal indicator
lamp.
The signal comes from the combination relay
(turn signal indicator with trailer coupling, rear
window defroster), wiper motor, ATA (N10/2),
on model 210 from the multi-function control
module (N10-1) or from the driver-side signal-
acquisition and actuation module (SAM)
(N10/1), on model 163 from the All-Activity
Module (AAM, N10), on model 168 it is
generated by the integrated turn signal
indicator control in the instrument cluster (A1).

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.

The remaining distance is displayed with a resolution of 100 km.
If a speed limit is set at the cruise control, the speed limit appears for a short moment in the display before
the ASSYST text.
In the normal case, it is the remaining distance which is displayed. However, the time information is always
processed in the background to enable the attention of "low-mileage drivers" to be drawn to any service due.
The remaining distance is compared each day with the remaining time. In certain circumstances, the display
switches over, and it is the remaining time which is displayed ( see document "Remaining time").
If certain measured values are not supplied to the ASSYST system, e.g. because of failure of a sensor, it
switches over to stored substitute values. A corresponding entry is made in the fault memory of the relevant
control module.
The data are retained if the operating voltage is disconnected or fails.

Warning threshold (in days)
With the HHT it is possible to set a warning threshold of between 5 and 30 days for the remaining time, with a
stepwidth of one day. The basic setting is 30 days.
Display of remaining time
The remaining time is always only displayed in those cases where the following condition is met:
Remaining time (in days) x 40 < remaining distance (in km), and the warning threshold is reached.
The remaining time is displayed in the following cases:
automatically, after 5 s start switch in position 2 or driving, if the warning threshold is reached:
The service symbol and the readout "SERVICE IN ... DAYS" appears for 10 seconds. (On vehicles not
fitted with multifunction display, the current remaining time, the service and the clock symbol appear.)
automatically, after 5 s start switch in position 2 or driving, if the remaining time is exceeded:
The service symbol and the readout "DAYS ... EXCEEDED" appears for 30 s (for 10 s up to mid-July
97). (On vehicles not fitted with multifunction display, the service and the clock symbol appear. The
"remaining time" is displayed with a negative sign (minus sign). The readout flashes in this case.)
After the display reaches the maximum readout of -730 days, the readout remains at this figure! The
readout is displayed with a resolution of 1 day.
As of approx. 06.97 a brief warning signal sounds in addition.
at driver request. The readout is then displayed, as above, for 10 s.
If a speed limit is set at the cruise control, this speed limit is displayed for a short moment before the
ASSYST display.
If certain measured values are not supplied to the ASSYST, e.g. because of failure of a sensor, it switches to
stored substitute values. An appropriate entry is then made in the fault memory of the particular control module.
If the power supply fails, the data are retained. The times without operating voltage (battery disconnected) are
not recorded, however! They can be retroactively included, however, with the HHT.

The opening angle of the throttle valve will only be determined by the accelerator pedal specification when no
limiting functions are active.
The accelerator pedal position is detected by the set value potentiometer (B37r1) or Hall sensor in the pedal
value sensor (B37) and information is released to the ME control unit (N3/10). In this way, the ME-SFI control
unit determines the position of the throttle valve and actuates the throttle valve motor (M16/1 m1).
The actual value potentiometer in the actuator (M16/1r1) signals the throttle valve position back to the ME-SFI
control unit.
The second potentiometer in the actuator (M16/1 r2) and the second signal from the pedal value sensor
(potentiometer or Hall sensor) supplies a reference value for the plausibility check. In addition, the system
switches over to the second potentiometer or the Hall sensor if the first potentiometer or Hall sensor fails
(emergency mode).
Adaptive accelerator pedal (model 203, 209, 211, 215, 220, 230):
The engine control unit recognizes how the accelerator pedal is being actuated and switches between
characteristic curves. Eighty percent of the engine load is released for a pedal travel of about 50 % for a sporty
driver and about 40 % for a quiet driver. There is no further difference felt above a pedal travel of about 90 %.
If, for example, the characteristic curve for a quiet driver is active after a long drive on the motorway then the
accelerator pedal must be pressed down unusually hard to obtain a higher acceleration level.
Kickdown switch (S16/6)
The kickdown switch was no longer used from 9/01. Recognition of full load is now achieved over the signal
from the pedal value sensor. The pressure point on the accelerator pedal before achieving the full load position
remains.
