Task
The electronic selector lever module control module (N15/5) receives digital and analog input signals, converts
these signals and controls various components or transfers information to various control modules via CAN.
In selector lever position "D" lateral touch movements in the "+" or "-" direction are detected by the electronic
selector lever module control module (N15/5) via two contacts and are conveyed to the ETC control module
(N15/3) via the engine compartment bus. See Fig. 99
and Fig. 100 .
The selector lever positions are determined by the slider position of the potentiometer and transferred to the
electronic selector lever module control module 90 (N15/5).
The selection diagram symbols (shift pattern display) are illuminated by means of LEDs when low beam is
switched on.
Input signals:
Selector Lever Position (From Potentiometer (90))
Touch Button +/-
Voltage Supply (Terminal 87)
Power Supply For Reverse Lamp (Terminal 15)
Signal For Shift Gate Illumination (Terminal 58D)
Kickdown Switch (S16/6)
Stop Light Switch (S9/1)
Input & Output Signals:
Datalink connector (X11/4)
Output Signals:
R/P locking solenoid (89)
Power supply and ground for potentiometer
Reverse lamp (via the light module (N7-1)).
Via The Engine Compartment Bus, There Are Connections To The:
ETC (EGS) Control Module (N15/3)
Traction System Control Module (N47)
The Following Information Is Received:

The aim of using the torque converter lockup clutch is to reduce the fuel consumption and exhaust gas
emissions of the vehicle by reducing torque converter slip. See Fig. 159
. This stands in contradiction to the ride
comfort demands made on the drive train with regard to its vibration behavior. The task of the electronic
transmission control is therefore to close the clutch in all driving situations relevant to fuel consumption, if
possible, and ensure that the engine vibrations are isolated from the drive train.
The characteristic curves shown in the diagram illustrate the different operating states of the torque converter
lockup clutch in relation to the accelerator pedal position and transmission output speed, plotted for one
transmission gear.
In addition to the evaluation of these characteristics, the status of the torque converter lockup clutch is also
determined by other variables.
Variables influencing the states of the torque converter lockup clutch:
Accelerator Pedal Movement
Uphill And Down Hill Gradients
Transmission Shift Functions
ATF Temperature
Durability Requirements
Load Condition
Engine Control Influences

.
Torque Converter Lockup Clutch Control Pressure, Function
Apart from extreme states of open or closed, it is possible to operate the torque converter lockup clutch with
preset slip speeds. To enable this variable control pressure must be applied to the torque converter lockup clutch
regulating valve.
The torque converter lockup clutch control pressure is adapted to each operating state via the pulse-width
modulated torque converter lockup solenoid valve (Y3/6y6) which is actuated by the ETC control unit (N15/3).

4-channel power amplifier for vehicle loudspeakers
System interlinkage
The radio and navigation unit (A2/56) is provided with the following components for data exchange with
external digital components:
CAN (A1 -A2/56)
The radio and navigation unit (A2/56) is connected with the instrument cluster (A1) via a separate
CAN bus. The difference to the other CAN systems is indicated by the spelling CAN bus (A1-A2/56).
The CAN bus (A1-A2/56) allows the following functions:
Operation of the radio and navigation unit (A2/56)is also possible with the multifunction steering
wheel.
The multifunction display (A1/p13) in the instrument cluster (A1) can display navigation
information on the current operating status of the radio and navigation unit (A2/56) .
The connection to the CAN bus (A1-A2/56) is only realized on models 208 and 210. (Status 3/99)
Digital data bus (D2B)
Data can be exchanged between the external audio components, the telephone system and - if present -
the voice control system over the D2B bus. This allows control data as well as the actual audio signals
(e.g. music from CD changer) to be transferred.
The only additional D2B component presently possible is the CD changer (A2/6) (Status: 3/99)
K bus (diagnostic interface)
Data exchange is accomplished between the diagnostic interface and the hand-held tester (reading out
DTCs and actual values, ...).
The communication between the HHT and all other D2B components is accomplished over the radio
and navigation unit (A2/56) diagnostic interface.
