Electricand Electronic Systems

The rain and twilight sensor ECU interfaces with the CAN line, with the windscreen wiper ECU (CTC) and with the body computer node (NBC) (for the twilight sensor)

It manages the following functions:

•Serial A-BUS line to rain/twilight sensor

•+15 for twilight/rain sensor ECU

WINDSCREEN WIPER ECU (CTC)

Electricand Electronic Systems

The Windscreen wiper ECU is an electronic and electromechanicalcontrol unit which operates the windscreen wiper motor according to the informationreceived via the A-Bus from the rain sensor and the steering column stalk commands (wired directly)

The CTC interface performs the following functions:

•It receives and transmits information via serial line (rain sensor signal, windscreen wipers activated)

•It interconnects with the front wiring

•1st and 2ndspeed control signal from steering column stalk

•Rain sensor sensing range controlled from steering column stalk

•Windscreen washer pump control signal from steering column stalk

•Power supply for windscreen wipers ECU

•Power supply for windscreen wipers

MOTION-SENSING ALARM ECU (CAV)

The CAV is an electronic component supplied with the front ceiling light which is connected to the serial A-bus line by means of the inside roof panel wiring.

It incorporates the motion-sensing anti-inclination sensors and it manages the motionsensors' deactivation buttons

ALARM SYSTEM SIREN ECU (CSA)

The Alarm System Siren ECU performs the following functions:

•It receives/ transmits information regarding diagnosis and attempt theft to the body computer node (NBC) via serial A-BUS line.

•It interconnects with the front wiring

TV NODE (NTV)

Electricand Electronic Systems

The module consist of a Diversity Television receiver with aerials incorporated into the rear window

It interfaces with the user by means of the NIT via I-CAN

It interfaces with the television wiring harnass.

HI-FI AMPLIFIER SYSTEM (DSP)

The hi-fi system amplifier interconnects with the rear wiring.

It manages the following functions:

•Signal for front and rear woofer.

•Rear LH and RH speaker

•Centralspeaker

•Secondaryamplifiersactivation.

IT NODE (NIT)

Electricand Electronic Systems

The IT Info Node is an ECU located in the centre of the dashboard which integrates informative, IT, audio/ video and air conditioning and heating system programming functions. The NIT has a multifunction display and a series of controls for interaction connected to the main electronic unit.

The IT Node -NIT-performs the following functions:

•It receives and transmits information via B-CAN line (e.g.: diagnosis, data)

•It incorporates the menu interaction controls

•It manages a high definition colourdisplay for varied information and navigation or the TV

•It interconnects with the dashboard wiring for the connection tothe vehicle’s electric system

•It interconnects with the IT wiring for the point-to-point connection with the TV tuner, CD changer

•It interfaces with the GPS, GSM and radio aerials by means of coaxial cables

•Vehiclesetup

N.B: The telephone module (opt.) is fitted separately underneath the Silver Box.
