Reset the immobiliser dashboard warning light

[Megb8848]

Hi All,
Wondered if anyone can help? I have a 2011 Hymer based on a Fiat Ducato 160 multijet. The engine electrics cut out intermittently several times (blowing the main ignition circuit fuse in the engine compartment each time) and this was eventually traced to an intermittent short circuit. The mechanic (in France) disabled the factory Fiat immobiliser that’s built into the ECU unit in order to get the engine restarted, having patched up the wiring fault in a temporary fix to get me back home to UK. Happily, I got home OK and now the short circuit in the wiring has been permanently repaired. I am inclined the leave the immobiliser within the ECU permanently switched off, rather than restore it to its original factory state. However I now need to reset the immobiliser warning light that remains permanently illuminated on the dashboard.
Does anyone know how to go about switching this warning light off? I guess I need to reset it somehow.
Thanks!

Reset is probably only possible by reversing ECU back to factory setting. Insurance a potential problem without original immobiliser.

The warning light is a consequence of the immobiliser (ECM) being unable to communicate with the key. The only realistic way to extinguish it is to restore the functionality of that system.

Hi & welcome.

A piece of black tape surreptitiuosly positioned does the ob.

Thanks for the replies. I’ll investigate restoring the ecu to its original software state. If that’s too expensive then I’ll have to remove the bulb.
