Tasks

The ETC (N15/3) control unit determines the current working parameters of the vehicle and exercises control of consecutive gear shifting, proceeding from simplicity of switching and parameters of the movement.

Activation of electromagnetic valves of switching is carried out at the command of the ETC (N15/3) control unit. The required size of pressure is calculated on the basis of the entering data and necessary adjustment adjustment of the transferred torque.

Is exposed to processing the following data arriving from other systems:

ME-SFI (N3/10)/CDI control unit (N3/9)

· The torque developed by the engine;
· Gear shifting;
· Emergency operation;
