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.
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)
- W/S recognition switch (S16/10)
- W/S program switch (S16/10s2)
Input and output signals:
- Datalink connector (X11/4)
Output signals:
- Reverse/parking lock valve (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))
In addition there is a connection via the engine compartment bus to the:
- ME-SFI [ME] control module (N3/10)
- Traction system control module (N47)
The solenoid valves for the modulating and shift pressure and for the gearchanges are actuated by the ETC control module (N15/3).
gearchanges 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.
This involves the processing of the following data from other systems:
ME-SFI control module (N3/10) or CDI control module (N3/9)
- Engine torque
- Engine speed
- Accelerator pedal position
- Gear shift
- Engine status
Traction system control module (N47)
- Wheel speeds
- Gear shift
- Traction status
The following information is output to other systems:
ME-SFI control module (N3/10) or CDI control module (N3/9)
- Kickdown switch (S16/6)
- Engaged drive mode
Traction system control module (N47)
- Transmission ratio
- Speeds
