FIAT PUNTO LPG
ELECTRONIC CONTROL
UNIT
The vehicle has a dedicted electronic con-
trol unit for the LPG system; it uses the
incoming signals from the petrol injection
control unit and converts them into sig-
nals for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(phased, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 7is located on
the protective fuse flap (left side 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.
The red LED indicates the reserve con-
dition;
ON. LPG operating mode indicator:
green LED, located under button A, on
constantly;
OFF. petrol operating mode indicator:
yellow LED, located above button A, on
constantly.
IMPORTANT When the ignition key is
turned to the MARposition the LEDs on
the ignition switch come on in accordance
with the following logic:
– with the petrol operating mode se-
lected: yellow OFFLED on;
– with the LPG operating mode se-
lected: all the LEDs in the switch are on
constantly and the green ONLED is flash-
ing. To select the type of fuel system desired
(LPG or petrol), press the button A-fig.
7.
To change the type of fuel system, it is ad-
visable to operate the button with the ve-
hicle stationary and the engine running or
,whilst driving, after having released the
accelerator.
If the switching takes place during accel-
eration or pick-up, there may be a brief
flat spot (fall in power).

FIAT PUNTO LPG
Switching from petrol to LPG
When running on petrol: press the button
A-fig 7, the switch to LPG will take place
automatically at the first significant accel-
eration.
During switching:
– the LPG gauge Bcomes on;
– the yellow OFFLED goes out (petrol
operating mode);
– the green ONLED comes on switch-
ing from intermittent to on constantly
(LPG operating mode);
There is a series of 5 LEDs B(1 red and
4 green) on the left side of the switch that
display the amount of LPG in the tank.
When the amount of LPG remaining goes
below about 1/5 of the capacity of the
tank, only the red (reserve) LED remains
on to signal the need for refuelling.
IMPORTANT In the case of starting at
outside temperatures of below -10°C, the
switching times from petrol to LPG in-
crease to allow the pressure regulator to
become warm enough.IMPORTANT The buzzer warns the dri-
ver that the engine is running on petrol;
therefore they must refuel with LPG be-
fore it runs out.
It is possible to deactivate the buzzer by
pressing switching button A.
Do not switch between the
two operating modes whilst
starting the engine.Switching from LPG to petrol
When running on LPG: press the button
A-fig. 7.
During switching:
– the LPG gauge Bgoes out;
– the yellow OFFLED comes on con-
stantly (petrol operating mode);
– the green ONLED goes out (LPG op-
erating mode).
LPG used up
If the LPG runs out, switching to petrol
takes place automatically with:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning from the switch
buzzer (fast frequency).

CAPACITIES

- including a reserve of . . . . . . 5-7 litres
LPG

capacity (*) . . . . . . . . . . . . . . litres 38
(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump and the max-
imum permitted capacity. There may be
slight variations to this figure as a re-
sult of: differences between the supply
pressures of pumps in the network,
pumps with different supply/cut off
specifications, tank not completely in
reserve condition..Note than when using a fuel such as LPG,
the range is very variable because, in ad-
dition to the vehicle driving and mainte-
nance conditions, it also depends on the
composition of the gas which may vary,
not only seasonally, but also from suppli-
er to supplier. LPG is, in effect, a compo-
sition of gas (butane and propane) mixed
in a way that may not be standardized.
During LPG operation, the “Instant con-
sumption” and “Average consumption”
readings are not significant, but remain
valid for all other functions.
IMPORTANT Only use LPG for mo-
tor vehicles. If, when refuelling with LPG,
the tank is filled with more
than the 38 litres, seek assis-
tance immediately from a Fi-
at Dealer. Periodically (at least once
every six months) it is advisable to let
the LPG in the tank run out and, at the
first refuelling, check that it does not
exceed the maximum capacity of 38
litres.
