Citroen C4 Grand picasso year 2016 wiring diagram

[fuzz1]

Hi

I have a Citroen C4 grand picasso year 2016 that was damaged in an accident and will not start. Giving lots of codes but I suspect the control box for the gearbox that is preventing the car from starting. The ecu of the gearbox was hanging under the front bumper of the car. The car will not go in park mode but stays in Neutral mode. When disconnecting the ecu the cars shifts into L2. Also says communication with gearbox lost.


I do not know what the ecu was nor has the number as it was smashed and the cover is gone. No part number left.

Any help most welcome.

Is there any possibility to shift manually the gearbox into park for the car to start?

The engine starts also in Neutral as all cars in the world with automatic gearbox.
Post VIN nr for further advises.
