ETC control module, task - GF27.19-P-4012-02X

Transmission 722.6 in model 240 

Input and output signals 

CAN databus 

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.

It receives operating data in the form of input signals from:

• Starter lock-out contact (Y3/6s1)
• Transmission oil temperature sensor (Y3/6b1)
• Rpm sensor 2 (Y3/6n2)
• Rpm sensor 3 (Y3/6n3)

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

• Instrument cluster (A1)
• ME-SFI [ME] control module (N3/10)
• Electronic selector lever module control module (N15/5)
• ESP, SPS [PML] and BAS control module (N47-5)
• DTR control module (N63/1)
• for EIS control module (N73)
• Central gateway control module (N93)

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 [ME] control module (N3/10) 

• Request: Move off in 1st gear
• Request: Active downshift
