C - OPERATING MODES
1 - Nominal mode
The BSI calculates the total distance travelled from the signal supplied by
the speed sensor. It then encodes the value in a VAN frame and sends it
to the control panel.
The control panel calculates the distance remaining to be travelled before
the next service using the following parameters:
• the maintenance frequency stored in the control panel (this is
decremented as miles are driven),
• the time elapsed (incrementation of the number of days).
As soon as one of these parameters (time or remaining miles) becomes
due, the multifunction screen indicates that the servicing date has been
exceeded (LED V19 flashes, remains illuminates and the message
remains displayed).
2 - Configuring the usage mode
The following procedure is used to select the Severe or Normal usage
mode of the vehicle.
1 - Press the Tripometer reset button.
2 - Switch on the ignition.
3 - Release the button within 10 seconds.
The instrumentation screen displays a key (LED V19) and the current
configuration of the vehicle, directly displaying the frequency of
maintenance operations.
Pressing the reset button briefly switches between the configuration
modes.
4 - Press for 10 seconds to validate.
The procedure exits automatically.
5 - Switch off the ignition.
