Tasks
ETC control unit (N15/3) determines the current operating parameters of the vehicle and performs sequential shift control based on the ease of shifting and driving parameters.
Activation of the switching solenoid valves is carried out at the command of the ETC control unit (N15/3). The required pressure value is calculated on the basis of the input data and the necessary correction adjustment of the transmitted torque.
The following data coming from other systems is processed:
ME-SFI control unit (N3/10) /CDI (N3/9)
- Torque developed by the engine;
- Gear shift;
- Emergency mode;
- The functioning of the tempostat;
- Activation of the speed limit system;
- Starter operation;
- Activating kickdown mode (as on models 01.06.02)
- Engine operating parameters.
Electronic shift lever control unit (N15/5)
- lever position;
- Transmission mode switch (S16/5);
- Kickdown activation switch (S16/6) (to 31.05.02)
Anti-slip system control unit (N47)
- Wheel speed;
- Torque of brake mechanisms;
- The fact of squeezing the foot brake pedal;
- Parking brake status.
EIS control unit [EZS] (N73)
- Condition of contact terminals;
- transmission option.
- Dashboard (A1)
- Selector lever position/selected gear.
Anti-slip system control unit (N47)
- transmission option;
- Information about the selected transfer.
ME-SFI control unit (N3/10) /CDI (N3/9)
- Torque developed by the engine;
- Emergency mode;
- Activation of the driving mode;
