Tasks
The control unit ETC (N15 / 3) determine the actual operating parameters of the vehicle and controls the sequential shift transmission, on the basis of ease of switching and driving parameters.
Activating the solenoid valve switching is carried out by command of the control unit ETC (N15 / 3). The desired pressure value is calculated based on incoming data and correction adjustment required transmitted torque.
Undergoes the following processing data coming from other systems:
The control unit ME-SFI (N3 / 10) / CDI (N3 / 9)
?� The engine torque;
?� Gear;
?� Emergency mode;
?� Operation Tempostat;
?� Activation of the speed limit;
?� The operation of the starter;
?� Activation mode kickdown (both models, 01.06.02)
?� The operating parameters of the engine.
The control unit of the electronic gear shift (N15 / 5)
?� The position of the lever;
?� The gauge-switch modes of transmission (S16 / 5);
?� The gauge-switch activate the kickdown (S16 / 6) (on 31.05.02)
Traction control system control unit (N47)
?� Speed of wheels;
?� The torque brake;
?� Fact squeezing the brake pedal;
?� Parking brake status.
The control unit EIS [EZS] (N73)
?� Status of contact terminals;
?� Option transmission.
Dashboard (A1)
?� Position selector lever / gear selected.
Traction control system control unit (N47)
?� Option transmission;
?� The information on the selected program.
The control unit ME-SFI (N3 / 10) / CDI (N3 / 9)
?� The engine torque;
?� Emergency mode;
?� Activation of the motion;
?� Selector lever position P / N;
?� The gauge-switch modes of transmission (S16 / 5)
?� Option transmission.
