Task The solenoid valves for the modulating and shift pressure and for The ETC control module (N15/3) determines the instantaneous the gearchanges are actuated by the ETC control module (N15/3).operating condition of the vehicle and controls all gearshift The pressure required is calculated from all input signals, adjusted sequences taking into account the ease of shifting and the driving to the torque to be transferred. The following information from other situation. systems is then processed:This involves receiving, converting and transmitting various digital

ME-SFI control module (N3/10) or CDI control module (N3/9)and analog signals.Engine torqueEngine speedIt receives operating data in the form of input signals from:

Starter lock-out contact (Y3/6s1) Accelerator pedal positionRpm sensor 2 (Y3/6n2) Gear shiftRpm sensor 3 (Y3/6n3) Engine statusTransmission oil temperature sensor (Y3/6b1)
