Warning lamp

Placed on instrument cluster, it acquaints the driver of system
correct operation or possible failure.

Inserting the key to ride position, central unit makes a system
test putting on the warning lamp and keeping it on for a time
of about “1 second”.

If it goes off after said time, it means that the key was
acknowledged and system is working. On the contrary, if it
behaves in a different way, it means that

key was not

acknowledged (star-up not possible).

6AS 400 A O.D. VD AUTOMATIC TRANSMISSION

Description of operation

The gear engaging system of the 6 AS 300 VD gearbox is a combination of a traditional system of the mechanic type and an electric
one.

Below are the main components of the system:

1) electronic control unit;

2) gear selecting/engaging actuator;

3) gear shift lever;

4) clutch actuator;

5) display/buzzer.

In the manual mode, the first gear is used to start the vehicle.

In the automatic mode, you just need to act on the selection lever (A/M): the gear is selected directly by the control unit.

The electronic control unit picks up all the signals required to meet the safety conditions and the parameters programmed in the
same. It also drives the electric actuating motor(s) for gear selection/engagement and clutch control.

The information required for driving is in any case made available to the driver by means of the display.

To ensure correct management of the gearbox and the other auxiliary functions provided for by the system, the
control unit is interfaced (CAN line) with the other electric and electronic system fitted to the vehicle.
