Unfortunately, I don’t get any help at the Lancia Forum and because the topic is important and the car to the Tüv must next month I need some support.It’s about the 843 Ypsilon from Lancia. Motor and electrics should be the same with the Punto 188. Maybe I can save some time and work.The little one has had problems with the ECU for several days. while turning the key on ignition all messages go on: lamps at the front back , airbag, doors and tailgate and what else do I know. rie is replaced, mass cable from battery to body and transmission cleaned and measured through (0.5Ohm), control unit plug connection, cleaned on mass and now I have the body computer out and hoped that you can see something. The ECU Multiscan says u.a. U1601 . This error can not be deleted at all. It comes again and again. The others something and not always. Does anyone have a tip? The airbag control light is always on. Previously almost all control lights were on. I have both keys at the ignition lock at the moment. Did I read that it can also disturb? But that’s not what I think. Was that the same before. please help me;-) PS: Maybe it’s worth mentioning that the cars at the traffic lights are already running uneasy. otherwise the clean runs
