Recommandations précautions
4.1
Basic requirements
Before any consequent operation, it is essential to check :
•
the battery voltage,
•
the fuses,
•
that the shunt is correctly positioned on the BSI (the shunt should be in the
“Customer” position),
•
that the BSI is not in back-up mode (see : “Preliminary checks on the BSI”
below).
4.2
Warning
These procedures should be implemented only if the vehicle’s locking / unlocking
functions are working .

Functions
5.1
Hazard lamps
The acquisition of the request for lighting of the hazard lamps is by the BSI ECU.
5.2
Direction indicators
The acquisition of the lighting request is by the switch module under the steering
wheel.
The lighting of the rear direction indicators is controlled electrically by the BSI.
The lighting of the front direction indicators is controlled electrically by the Engine
Relay Unit (BSM).
