BUILT-IN SYSTEMS INTERFACE
The Built-in Systems Interface (BSI) is an ECU which incorporates:
•
•
Interface electronics (relays, fuses, diagnostic socket, HF receiver)
Control electronics: The BSI is one of the masters of the VAN network, on which it
controls communications between the ECUs
•
•
•
Calculation electronics: this controls the basic functions in an autonomous manner
(locking of the doors, signalling, visibility, interior lighting, engine immobiliser, etc).
Information about the vehicle for the anti-theft protection (vehicle's VIN code, key
codes, HF remote control code, radio identification, etc)
A program which is used to control the system and perform diagnostics and
configuration procedures.
The BSI acts as a gateway between the VAN network and the diagnostic tool.
In addition, it helps with energy management by controlling reduced consumption
modes for itself and the other multiplexed ECUs.
