The Body Computer is the central unit of the electrical system of vehicle under examination. Its task is to manage main functions
present.
Inside, it integrates “immobilizer” function; therefore, an external central unit is not present any more for this function.
Further, it manages:
- External and internal illumination
- Central door locking actuator controls, windscreen washers and wipers, front electric window winders, etc.
- Acquisition of switches and controls from steering column switch unit, pushbuttons, etc.
Inside, it integrates diagnosis connector EOBD (16 pins) for board diagnostics (previous diagnosis connector is not present any
more), it communicates with the two CAN lines present (Bcan, Ccan) and instrument cluster. It is mounted in the cab behind
interconnection central unit “CPL” and interfaces with it through a 20 pin lamellar connector located inside the component.
It interfaces with vehicle system through three connectors: two connectors are located in front side and one connector is located
in rear side accessed by tilting the whole assembly through unscrewing special securing screws.
Front connectors:
- cab wiring harness (black) connector “LN”
- bonnet wiring harness (blue) connector “AV”
