I do not know if the attached diagrams are still correct for your vehicle, as they relate to the introduction of the x250 model in 2006. My earlier x244 has the same fuse location for the ignition switch. The ignition switch fuse is a 30A(green) maxi blade fuse. The engine bay fusebox is supplied by a fuse at the battery positive terminal.

I have this but my one has fuse 16 engine bare 7.5amp that not on this fuse box diagram in engine bare that has no power and fuse 37 on the bcm 7.5amp inside would you have the ignition switch diagram layout please with the above number fuses

I am sorry, but I do not have the exact information that you seek. The information previously provided should be OK for x250 vehicles, but may have some need some changes for later vehicles. On my even earlier x244, I believe that it is F16 that supplies ignition on signal to the ECU to start the key code recognition, which is very fast if all items are working correctly. If there is no supply to F16, and function is the same then key code symbol will not illuminate and then go out.

I had missed the fact that the vehicle will not crank. This function is very basic, but in an automatic you have to select "P" before engine will crank. (I have a Skoda autonatic, and this also allows cranking with "N" selected.) On the x244 Ducato this interlock was provided by a relay with contacts in the starter solenoid circuit. The relay position has obviously changed as it is now designated for cooling fan (T06). However I see that Relay T20 is shown as spare in diagram. Perhaps this relay controls the starter solenoid and is not being operated from the transmission selector contacts?

Another possibility to consider is a faulty engine bay fusebox. These have been reported for going either open circuit, or short circu The latter due to overheating at faulty connections.

Others with later models and auto transmission may be better informed than myself.

Hi would you have a wirering digram for the ignition switch for this model?

I am sorry, but I doubt that there any any generally avaiable diagrams for a 2021 Ducato Automatic. The vehicle probably has Stop/Start fitted, which wiil need a connection to the starter solenoid circuit. In post #4 I suggested the probable interlock with the transmission selector. Has this been investigated?

Hello. Maybe this will help...

Hello. Maybe this will help...

Thanks to @Dmitry Shvedov for posting the very interesting document.

From a quich scan of the diagram, I note that the gnition switch is only supplied via a 7.5A fuse, F53, and that the starter solenoid control signal is routed via the BCM, M001, where it is switched by relay T39. The power to the solenoid is also controlled by relay T55. This relay is in turn controlled by the engine control computer, M010.

Perhaps after studying the descriptive text, I may have to change my ideas.

I think this not the right dirgram for this model it has F16 in engine bare and F37 on the bcm both bring up the dash on

Here is the diagram for your VIN. Fiat has a mess in TIS with diagrams. Automatic transmission with IBS sensor.
