Model, year would help, but sounds like immobiliser...?

 

[irnbru]

Try using your key fob remote to lock / unlock doors. That might clear it.

Generally this means there's a problem with the key \ immobiliser. Basically the immobiliser is not recognising the key code.
Have you tried the spare \ second key?
If still the same problem it may mean the key\s need recoded.
Others with more info will be along shortly who may be able to help with the recoding side.
The bit from the X250 manual.

THE FIAT CODE SYSTEM
This is an electrical engine immobiliser system which
increases protection against attempted theft of the
vehicle. It is automatically activated when the ignition
key is removed.
Each key contains an electronic device which
modulates the signal emitted during ignition by an
antenna built into the ignition device. The modulated
signal, which changes each time the engine is started,
is the “password”, by means of which the control
unit recognises the key and enables to start the
engine.
OPERATION
Each time the vehicle is started turning the ignition
key to MAR-ON, the Fiat CODE system control
unit sends a recognition code to the engine control
unit to deactivate the inhibitor.
The recognition code is sent only if the Fiat CODE
system control unit has recognised the code
transmitted from the key.
Each time the ignition key is turned to STOP, the Fiat
CODE system deactivates the functions of the
engine management control unit.
If the code has not been recognised correctly, the
warning light turns on accompanied by the
related message on the display (see section “Warning
lights and messages”).

In this case, turn the key to STOP and then to
MAR-ON; if it is still locked, try again with
the other keys that come with the vehicle. Contact a
Fiat Dealership if you still cannot start the engine.
IMPORTANT Each key has its own code which must
be stored by the system's electronic control unit.
Contact the Fiat Dealership to have new keys (up to
eight) stored with the code.
Warning light switching on while driving
❒ If the warning light switches on, this means
that the system is running a self-diagnosis (for
example for a voltage drop).
❒ If the warning light stays on, contact a Fiat
Dealership.
The electronic components inside the key
may be damaged if the key is subjected
to strong shocks.

Hi.. what's the Base vehicle... I'm assuming fiat...
If you give a few more details of vehicle like year and engine variant etc it may help get some replies..
Have you googled it... there seems to be quite a bit on that problem on fiat related threads ..
Andy.

 

[sean n maggie]

it,s FIAT Ducato 3ltr 2008

 

[sean n maggie]

Just noticed on dash screen, its saying check transmission, refer to handbook...but i cant find anything about it in there....

[SpeedyDux]

What other keys?

 

[sean n maggie]

What other keys?

i have 2 keys, the main one with remote locking etc and a basic key,,,none of them will start the van..

 

[ChrisL]

Is it automatic? if so is it in park or neutral with your foot on the brake?

I wasn't being flippant, in case you were wondering. My dealer tells me that I will only get one remote locking key with the new van. I have always expected 2 remote locking keys until now. My previous VW California came with 2 such keys and a 3rd non-remote key. If the FIAT spare non-remote key can start the engine I am going to test that on handover. Scroogy FIAT!

I hope you get your non-starting issue resolved quickly.

 

[Mr Dog]

We had same problem on a 2009 3l manual, turned out to be a dodgy earth cable from gearbox to chassis.

 

[Bobby22]

http://forums.outandaboutlive.co.uk...2-50-engine-gearbox-earth-strap-again-/33081/

I have read somewhere that if this happens it is advisable to renew the earth cable from gearbox to chasis ( as above) . Even cleaning old one might not work.

Edit check out link

Thank you for the help ,,will try a new earth strap tomorrow,,,so long as i can find it and get under the van, not easy having only 1 leg,,,,,But will be trying anyway,,,,,,thanks again everyone....

 

[jockaneezer]

Just try putting a jump lead from a good earth point on the gearbox/engine onto the negative post of the battery and try that.

 

[Emmit]

I had this prob. some time ago.
It was resolved when I discovered? that I had the car keys in my pocket.
Don't ask me the reasoning but the Audi car keys somehow 'stopped' the Ducato from starting.
Put them on a rock 10yds away and the 'van started.
Worth a try.

will try that in the morning...

 

[sean n maggie]

just to say, the engine turns over fast, but due to the immobilizer light being lit up, it wont start,,,,,,and the transmission warning is coming up,,,fingers crossed it is just a bad earth...

 

[sean n maggie]

in neutral with brake pedal down

Have tried a lead from negative terminal on the battery to the engine to earth it,,,still no good,,,,looking like having to join the RAC to get them out and if they cant solve it, it looks like a recovery to a fiat garage,,,,,,NOT looking good......

 

[Lorryman100]

Disconnect the engine battery terminals and touch the two disconnected leads together to discharge any capacitance in the loom. If you have an alarm BBUS (Battery Back Up Sounder) disable this first before disconnecting the engine battery. The owners manual will describe the process in how to disable the BBUS. If you have a B2B charger or the habitation batteries power the engine battery in any way disconnect the negative terminals, if there are solar panels disconnect the + wire at the regulator before disconnecting the hab batteries. Wait 10 minutes and then re attach the battery, live first then the negative terminal ( reconnect the hab batteries and then the solar if previously disconnected). This will reset the EMS/IPAC/Alarm and is sometimes all that is needed to reset the immobiliser. Arm the alarm and then disarm and then go through your normal engine start routine. HTH

 

[Lorryman100]

Meant to say that it would be a good idea to have handy the radio code if your radio needs one, as after disconnecting the battery will reset the radio to factory mode.

tried that this morning,,still no luck,,,,but thanks for trying to help...

Ok that is the basics out of the way. If you look through the handbook there should be some sort of bypass in case you lose your fob. Each manufacturer has a different name for it but the norm is a EKS code which will bypass the immobiliser for one ignition cycle. It is 4 digits and there are different ways of entering the code ie: switching the ignition on and off to opening and closing the drivers door the number of times corresponding to each digit of the EKS code. Enter the code and let me know if the engine starts. You could also try a fob resync which involves locking and unlocking using the fob a minimum of 4 times, though this number is dependent on what is factory set. The easiest option would be to plug in one of my diagnostic tools and read what the fault is which is of no help to you so the best option for now would be the fob or plip resync to see if that cleared the issue followed by the EKS code. If the vehicle fails to start after the EKS code has been entered let me know and we will move onto the next set of options.

Screenshot from Landrover diagnostic screen of alarm unit as an example.

[Lorryman100]

Just had a look on my autologic for your vehicle and the EKS is a 5 digit code which should have been included with the handbook when new. If it is not there you need to follow the instructions in the handbook and contact the International Security Register and go through their security to receive the codes. There should be a credit sized card containing 5 digits and 7 digits, the 5 digits are the EKS code.

 

[Lorryman100]

Another option for quickness would be to remove the ignition plastic shroud and check the connections on the transducer coil mounted around the ignition barrel. These have been known to come loose, intermittent contact loss due to vibration on other vehicles, worth a check.

The transducer coil is the black ring around the key barrel with Fit and an arrow on it.

 

[ChrisL]

With regard to reading fault codes, you can buy a bluetooth OBD2 dongle for around £12 and connect it to an app called Torque on your phone, this should be able to tell you what the fault is, it takes a little setting up but once done it works well or at least mine has. Torque can also do a lot more using the data it recieves so worth a look.
