FIAT BRAVO LPG
ELECTRONIC CONTROL
UNIT
The car has a dedicated electronic control
unit for the LPG system fig. 7; it uses the
incoming signals from the petrol injection
control unit and converts them into signals
for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(timed, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 8is located on
the central console near the handbrake
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 only
comes on when the last green LED goes
out.
The red LED indicates the reserve status;
ON. LPG operating mode indicator: green
LED on continuously, located under but-
tonA;
OFF. petrol operating mode indicator:
amber LED on continuously, located abo-
ve buttonA.
IMPORTANT When the ignition key is
turned to the MAR – ONposition, the
LEDs on the switch come on as follows:
– with petrol operation mode selec-
ted: amber OFFLED on;
– with LPG operation mode selected:
all LEDs on the switch are on continuou-
sly and the green ONLED flashes.
To select the type of fuel system desired
(LPG or petrol), press button A-fig. 8.
To change the type of fuel system, it is ad-
visable to operate the button with the car
stationary and the engine running or, whil-st driving, after having released the acce-
lerator.
If switching takes place during acceleration
or pick-up, there may be a brief flat spot
(drop in power).
Do not switch between the two operating
modes when starting the engine.
