The electrical / electronic system is characterised in the presence of two communication lines which manage vehicle electrical
system, directly controlling body functions, access, visibility, board information, comfort, etc.
The structure consists of two CAN communication networks to which all electronic central units present and instrument cluster
complete with display screen are connected.
A new central unit is also present: the Body Computer, which manages many functions present and communicates with both
CAN lines. For diagnosis, 38-pole connector is not present any more; on the contrary, a 16 pin connector is present named EOBD.
In particular, on CAN line named Ccan, connected are central units relating to vehicle systems and information for driver:
- Yaw sensor present with ESP8
- ABS
- Automatic gearbox
- EDC16
- Decelerator
- Digital tachograph
- Body Computer
This communication line is characterised in high speed data transmission relevant to electronic systems connected to it. It is
comparable to VDB line present on other vehicles.
Communication line named Bcan enables communication between Body Computer and the various central units employed for
the various board services. To this line connected is the instrument cluster, equipped with a display screen.
This communication line enables data transmission at a lower speed than above Ccan line.
Central units connected to this line:
- Body Computer
- Instrument cluster
- Radio and navigator
- Air Bag
- Rotating-translating door
