BODY COMPUTER NODE E04 (NBC)
SPECIFICATIONS
The BODY COMPUTER NODE manages some of the vehicle's electrical system functions.The NBC is housed under the dashboard near the steering column, in a central position in relation to the functions that it manages.The Body Computer Node (NBC) together with the Dashboard Control Unit (CPL) form the DASHBOARD NODE (NPL) where the former (NBC) constitutes the electronic section and the latter (CPL) the electro-mechanical section.The fuses and relays are fitted on the CPL, whilst the NBC houses the EOBD fixed connector used for the fault diagnosis via the K lines of the NCM, NFR, NCR and CAB.This is connector is also prepared for the dialogue with the B - CAN and C - CAN networks which can be used for both fault diagnosis and for possible on line programming.BODY COMPUTER NODE GENERAL FUNCTIONS
The NBC peforms the following functions:
- It receives and sends information on the B - CAN network (e.g.: fault diagnosis, warning lights, commands, data)
- It receives and sends information on the C - CAN network
- It interconnects with the dashboard, front and rear wiring
- It allows an interface for the fault diagnosis (EOBD)
- It connects to the CPL to take power supplies / signals and operate relays.
We find the following functions:
- management of the centre front courtesy light (20W) with timed switching off and dimming
- management of the two spot lights (10W) with timed switching off and dimming
- management of on/off exits at relay: headlamp washer pump, main beam headlamps, fog lights, dipped headlamps, services, heated rear windscreen
- on/off management of relay during right/left direction indicators or hazard warning lights for acoustic feedback
- management of on/off exits directly at loads and diagnostic function: front side lights (left and right), rear side lights (left and right), front direction indicators (left and right), rear direction indicators (left and right), side direction indicators (left and right), no. plate lights (left and right), brake lights (left and right), rear fog lamps (left and right);
- management of on/off exits directly at loads: heated rear windscreen LED, hazard warning lights LED, management of the sun roof;
- repetition of the vehicle speed signal
- management of the ideogram light (15W) driver
- management of the SBMT (35W) driver
- management of the recovery serial line to the engine management control unit (immobilizer)
- management of the serial line to the volumetric sensors, siren, anti-tilt, rain sensor, dusk sensor, steering column switch unit, tyre pressure control unit.
- master for the entire system: management of the IFRs at the slave nodes under direct jurisdiction and monitoring of the IFRs by the other master nodes, monitoring and management of protocol errors, timer control;
- fault diagnosis of the entire system: collection of diagnostic information, management of the fault diagnosis using the Fiat Lancia Tester
- anti-theft: management of the remote control receiver (RF) (excluding NBC192-FULL version), connection with volumetric sensors, the siren and the anti-tilt
- immobilizer: management of the key code with possible engine immobilizing
- acquisition of on/off signals: dipped headlamp operation, main beam headlamp operation, boot lock opening control, boot locking function, handbrake control, hazard warning lights control, left and right rear fog lamps control, fog lights relay feed, left direction indicators control, right direction indicators control, parking lights control, side lights control, city control, steering column switch unit auto control, headlamp washer control, FIS control, boot button, bonnet button, front brake pad wear (left and right), brake fluid level, reverse gear engaged;
- acquisition of analogue signals: fuel level, alternator voltage (D+), battery voltage, brake lights fuse status recognition, centre courtesy light control, left and right spot lights control, brake lights control
- acquisition of vehicle speed signal
- acquisition of lock sensors from door.
