COMPOSITION OF THE SYSTEM
System control unit
The electronic control unit receives the signals from the sensors/switches: the management and control of the system under
the different operating conditions of the gearbox are based on the above signals.
It is interfaced with other electronic systems available on the vehicle, such as EDC and ABS, through CAN communication lines.
A - Connector on the gearbox side
B - Connector on the vehicle side

Through the connection with the EDC 16 system, the gearbox control unit is able to detect the position of the accelerator pedal
and also the engine revs number.
Connection with the ABS8/ESP8 control unit is used to prevent the “UP” gear shift at bends and also control driving under poor
grip conditions in case of mode “A” driving.
The new ABS system controls “smart” warning lights incorporated into the on-board panel. These warning lights come on to
indicate braking system failure.
The “Brake” signal, upon start-up, comes directly from the EDC control unit. The reverse gear signal is direct.
