ELECTRONIC
CONTROL UNIT
The vehicle has a dedicated electronic
control unit for the LPG system; it uses
the incoming signals from the petrol in-
jection control unit and converts them in-
to signals for LPG injection.
The injector control unit works in the
same way as the petrol control unit
(phased, sequential, multipoint).

near the protective fuse compartment (on
the left of the dashboard) and includes:
A. LPG/petrol operating mode request
button;
B. LPG gauge: 5 LEDs, 4 green and 1 red
to indicate the reserve. The red LED on-
ly comes on when the last green LED goes
out.

ning on reserve;

green LED, located under button A, on
constantly;
OFF. petrol operating mode indicator:

logic:
