Hi Morgano, the car is Citroen C4 Picasso 2011, the car had two dtc U1400 (fault on LIN net) and U1401(Fault in slave node of the alternator LIN net), the workshop changed the alternator and the module, and the faults still appears. Any idea? I think that the fault is on the wires, i will check them tomorrow ...
