Task - The ETC control module (N15/3) determines the instantaneous operating condition for the vehicle and 
controls all gearshift sequences taking into account the ease of shifting and the driving situation. See Fig. 97
This involves receiving , converting and transmitting various digital and analog signals. 

Input signals:  

Starter Lock-Out Contact (Y3/6S1)  

RPM Sensor 2 (Y3/6N2)  

RPM Sensor 3 (Y3/6N3)  

Transmission Oil Temperature Sensor (Y3/6B1)  

Kickdown Switch (S16/6)  

Gear Recognition Switch (S16/10)  

Output signals:  

Reverse/parking lock valve  

Input and output signals:  

Datalink connector (X11/4)  

In addition there is a connection via the engine compartment bus to the:  

ME-SFI Control Module (N3/10) or CDI Control Module (N3/9)  

Traction System Control Module (N47)  

Transfer Case Control Module (N78)  

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)  

(Y66/1)  

Selector lever position P/N to the engine control module (ME-SFI) (N3/10) (only on detection of the 
selector lever position "P" or "N" on the transmission range recognition switch (S16/10) and at the starter 
interlock contact (Y3/6s1)).
