Task - The ETC control module (N15/3) determines the instantaneous operating condition of the vehicle and
controls all gearshift sequences taking into account the ease of shifting and the driving situation. This involves
receiving, converting and transmitting various digital and analog signals. See Fig. 96
.
It receives operating data in the form of input signals from:
Starter Lock-Out Contact (Y3/6S1)
RPM Sensor 2 (Y3/6N2)
RPM Sensor 3 (Y3/6n3)
Transmission Oil Temperature Sensor (Y3/6B1)
In addition there is a connection via the engine compartment bus to the:
Instrument Cluster (A1)
ME-SFI Control Module (N3/10) or CDI Control Module (N3/9)
The solenoid valves for the modulating and shift pressure and for the gear changes are actuated by the ETC
control module (N15/3).
The pressure required is calculated from all input signals, adjusted to the torque to be transferred. The following
information from other systems is then processed.
ME-SFI Control Module (N3/10) or CDI Control Module (N3/9):
Engine Torque
Engine Speed
Accelerator Pedal Position
Gear Shift
Engine Status
Electronic Selector Lever Module Control Module (N15/5):
Kickdown Switch (S16/6)
Selector Lever Position P/N
Traction System Control Module (N47):
Transmission Ratio
Speeds

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)
