The general principles of operation of the transmission system, the control signals

Driving / construction location of the main components of the electronic transmission control system and identification card terminals 13-pin AT shown in the illustrations.

Arrangement of electronic components of a control system AT

N15 / 3 - the transmission control module (TCM) S16 / 6 - Sensor-switch activate the kickdown	Y3 / 6 - Electric unit electro-hydraulic control unit switching

1 - 3 RPM sensor (Y3 / 6n3) 2 - E / magnetic modulating pressure control valve (Y3 / 6y1) 3 - 2 RPM sensor (Y3 / 6n2) 4 - Input temperature sensor (Y3 / 6b1) and contact blocking of a starter (Y3 / 6s1) 6 - Power supply e / solenoid valves 7 - Power supply sensor	8 - E / solenoid valve gear 2-3 (Y3 / 6y5) 9 - E / solenoid valve gear 3-4 (Y3 / 6y4) 10 - E / pressure control solenoid valve switch (Y3 / 6y2) 11 - E / solenoid valve (locking of the rotation) (Y3 / 6y6) 12 - Sensor housing 13 - E / shift solenoid valve 1-2 / 4-5 (Y3 / 6y3)

TCM (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.
