2006 FIAT DUCATO check engine

60GETTING TO KNOW YOUR VEHICLE
– a control unit connected to the
heater/ventilation unit for automatic
operation;
– an electronic control unit to check
and adjusted the integrated heater
burner;
– a digital timer A-fig. 85to start the
heater manually or to program staring
time.In cold weather, the supplementary
heater automatically warms and cir-
culates constant temperature fluid in
the engine cooling system for the time
required to ensure optimal engine ig-
nition and cab temperature conditions.
The heater can be started automat-
ically (programmed by means of the
digital timer) or manually by pressing
the “heat now” button on the timer.
When the heater is turned on (au-
tomatically or manually), the electronic
control unit operates the fluid circu-
lation pump and safely ignites the burn-
er.The electronic control unit also con-
trols the circulation pump delivery in
order to reduce initial heating time.
When the fluid reaches a temperature
of 30°C, the control unit operates the
passenger compartment ventilation
fan.
When the fluid temperature reaches
72°C, the electronic control unit re-
duces the burner power and stops op-
eration when it reaches 76.5°C. The
timer, circulation pump and heater fan
are kept running. When the fluid tem-
perature drops under 71°C the con-
trol unit automatically turns the burn-
er back on.

– Always remember to turn the
heater off when refuelling or standing
in service stations to avoid fires and
explosions.
– Do not park the vehicle over in-
flammable material such as paper, dry
grass or leaves: fire risk!
– The temperature near the heater
must never exceed 120°C (e.g. during
painting operations in a workshop
oven). Higher temperatures could
damage the electronic control unit
components.
– When the engine is off, the heater
runs off the battery: it is consequently
important to run the engine for a cer-
tain period of time in order to restore
the battery charge.– Follow the prescriptions in “Vehi-
cle maintenance” section at paragraph
“Engine coolant level” to check the
coolant level. The coolant in the cir-
cuit must contain at least 10% an-
tifreeze fluid.
– Maintenance and repairs must al-
ways be carried out by a Fiat Deal-
ershipand only genuine spare parts
must be used.
MAINTENANCE
Have the heater checked at a Fiat
Dealership periodically (always be-
fore winter). This will ensure safe and
cheap running and long appliance life.
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation
devices even for short periods of
time.
WARNING

85GETTING TO KNOW YOUR VEHICLE
Be very cautious operating
the engine compartment
when the engine is hot - danger of
burns! Wait until the engine cools.
WARNING
Scarves, ties and other
loose articles of clothing
could easily get caught up in mov-
ing parts. This can be extremely
dangerous for the wearer.
WARNINGCLOSING
Proceed as follows:
1)hold the bonnet up with one hand
and, with the other, remove rodfig.
135from recess Dreplace it in its clip
C;
2)lower the bonnet at approx. 20
cm from the engine compartment and
then let it drop, ensuring that it is ful-
ly closed and not just held in position
by the safety catch. If the bonnet does
not close properly do not push it
down but open it again and repeat the
above procedure.
For safety reasons the bon-
net shall always be perfect-
ly closed when travelling. Always
check for proper bonnet locking. If
the bonnet is left inadvertently open,
stop the car immediately and close
the bonnet.

Warning light >alone,
with the engine running,
normally indicates a fault in the
ABS system only. In this case, the
braking system is still efficient,
though without the anti-locking de-
vice. Under these conditions, per-
formance of the EBD system may
be reduced. In this case too, you are
advised to go immediately to the
nearest Fiat Dealership, driving in
such a way to avoid sharp braking
to have the system checked over.
WARNING
If the xbrake fluid low
warning light comes on,
stop the vehicle immediately and
contact the nearest Fiat Dealership.
Fluid leaks from the hydraulic sys-
tem, in fact, can compromise brake
system operation, both traditional
systems and systems with ABS.
WARNING
Braking while cornering always re-
quires extreme care even when using
ABS.
The most important advice to follow
is this:
If you follow these tips you will be
able to brake better in any situation.
IMPORTANTVehicles fitted with
ABS shall only be fitted with wheel rims,
tyres and brake pads of the make and
model approved by the vehicle manu-
facturer.The system is completed with an elec-
tronic brakeforce distributor called
EBD which improves braking system
performance by means of the ABSsys-
tem control unit and sensors.
When the ABS cuts in, and
you feel the brake pedal
pulsating, do not remove your foot,
but keep it pressed. In doing so you
will stop in the shortest amount of
space possible under the current
road conditions.
WARNING
The vehicle is fitted with an
electronic brakeforce dis-
tributor (EBD). The >and x
warning lights come on at the same
time when the engine is running to
indicate that there is an EBD sys-
tem failure. In this case violent
braking may be accompanied by
early rear wheel locking with the
possibility of skidding. Drive ex-
tremely carefully to the nearest Fi-
at Dealership to have the system
checked.
WARNING

96GETTING TO KNOW YOUR VEHICLE
The action of the ASR is particularly
helpful in the following circumstances:
– slipping of the inner wheel due to
the effect of dynamic load changes or
excessive acceleration.
– too much power transmitted to
the wheels also in relation to the con-
ditions of the road surface.
– acceleration on slippery, snowy or
frozen surfaces.
– in the case of loss of grip on a wet
surface (aquaplaning). Furthermore, the system is equipped
with a connector for interfacing with
specific tools used to read the error
codes stored in the control unit mem-
ory along with a set of diagnostic and
engine specific parameters.ASR SYSTEM
(Antislip Regulation)
The ASR system controls the vehicle
drive and cuts in automatically every
time one or both driving wheels slip.
In slipping conditions, two different
control systems are activated:
– if the slipping involves both the dri-
ving wheels, the ASR function inter-
venes reducing the power transmitted
by the engine;
– if slipping involves only one driving
wheel, the ASR system cuts in auto-
matically braking the wheel that is slip-
ping.
IMPORTANTAfter eliminating the
problem, your Fiat Dealershipwill
run a bench test to fully check the sys-
tem. In some cases, a long road test
may be required.Contact a Fiat Dealer-
ship as soon as possible if
the Uwarning light ei-
ther does not come on when the
key is turned to MAR or comes
on, with fixed or flashing light,
when travelling. Warning light U
operation can be checked by
means of special equipment by
traffic agents. Always comply
with the road traffic regulations
in force in the Country where you
are travelling.
The performance of the
system, in terms of active
safety should not induce the driver
to take pointless and unnecessary
risks. The style of driving must in
any case always be adapted to the
conditions of the road surface, vis-
ibility and traffic. Road safety is al-
ways the driver’s responsibility.
WARNING

SWITCHING THE ASR
SYSTEM ON AND OFF
The ASR function switches on auto-
matically each time the engine is
started.
When travelling the device can be
switched off and on again pressing
switch A-fig. 143 on the centre con-
sole.
Function deactivation is indicated by
the instrument panel warning light A-
fig. 144coming on. If the ASR func-
tion is turned off when travelling, it
will be restored at the following start-
up.For correct operation of the ASR
system the tyres must absolutely be of
the same brand and type on all
wheels, in perfect conditions and,
above all, of the specified type, brand
and size.
IMPORTANTWhen travelling on
snowy road with snow chains, it may
be helpful to turn the ASR device off:
in fact, in these conditions, slipping of
the driving wheels when moving off
makes it possible to obtain better
drive.

ASR system failure indication
In the event of malfunctioning, the
ASR system is automatically discon-
nected and the warning light Von
the instrument panel comes on with
fixed light.
Press once button A-fig. 143to
check that the signalled information is
correct:
– button pressed, the warning light
goes off, no ASR system faults are de-
tected;
– button pressed, the warning light
stays on, ASR system fault detected.
In this case the vehicle will go o as a
vehicle not equipped with this system.
Anyway, you are recommended to go
to a Fiat Dealershipas soon as pos-
sible.

IMPORTANTThe airtight seal of
the cap may lead to a slight increase of
pressure in the tank. A hissing sound
when the cap is removed is therefore
quite normal.
After refuelling, screw the cap until
hearing one or more clicks, turn the
key and then remove it.. close the lid.
IMPORTANTMoreover, before
starting the engine, for the sake of
safety, check whether the refuelling
gun is properly hung onto the fuel
pump.If required, replace the
fuel cap with another gen-
uine cap to avoid affecting
the efficiency of the fuel vapour
recovery system.

PROTECTING THE
ENVIRONMENT
Protection of the environment has
been the guiding principle in the design
of the Fiat Ducato right from the start.
The result is the use of materials and
creation of devices that can reduce or
considerably curtail harmful influences
on the environment.
The devices for curtailing petrol en-
gine emissions are:
– a three-way catalytic converter;
– a lambda sensor;
– a fuel evaporation system.
The devices for curtailing diesel en-
gine emissions are:
– an oxidising catalytic converter;
– an exhaust gas recirculation system
(E.G.R.) (for certain versions).
Consequently, the Fiat Ducato is
ready to travel well ahead of the most
stringent international pollution control
standards.
Keep naked flames or light-
ed cigarettes away from
the fuel filler hole as there is a dan-
ger of fire. Do not bend too close to
the hole either so as not to breathe
in harmful vapours.
WARNING

116GETTING THE BEST OUT OF YOUR VEHICLE
BUMP STARTING
Starting by pushing or towing the ve-
hicle is not possible. In the event of an
emergency, when the battery is flat,
start the vehicle with a suitable emer-
gency battery, following the instruc-
tions given in section “In an emer-
gency” at paragraph “Jump starting”.
TOWING THE VEHICLE
IMPORTANTFor towing the ve-
hicle comply with current local regu-
lations and follow the instructions giv-
en in section “In an emergency” at
paragraph “Towing the vehicle”.If the vehicle is to be towed, adhere
to the following recommendations:
– if possible, carry the vehicle on the
floor of a rescue vehicle;
– if this is not possible, tow the ve-
hicle raising the driving wheels (front)
from the ground;
– if this, too, is not possible, the ve-
hicle should not be towed for more
than 200 km at a speed of no more
than 50 km/h.
When towing, the gearshift lever
should be at N.
Do not start the engine
while the vehicle is being
towed.
The failure to comply
with these instructions
may cause serious dam-
age to the automatic gearbox.
When travelling with the
gearbox faulty, drive with
the utmost care in consideration of
the limited performance (in terms
of acceleration and speed) that the
vehicle can offer.
WARNING
When travelling with the
gearbox faulty, the revers-
ing gear lock might not be active:
absolutely never move the lever to
the R position with the vehicle on
the move.
WARNING– Warning light flashing= auto-
matic gearbox fault.
Warning light flashing at starting or
when travelling indicates a fault in the
automatic gearbox.
The automatic control system sets
an “emergency programme” engaging
the 3
rdgear.
Switching the engine off and then on
again, the self-test system could ex-
clude the fault and therefore turn off
the warning light. The failure is how-
ever stored and the automatic gear-
box shall be checked at a Fiat Deal-
ership.
