Hello everyone. I've been having some annoying technical problems with my Fiat Grande Punto 1.4 T-Jet from 2008.
When I bought the car used around 2 years ago the rear windscreen wiper motor was broken. And so was the wiring harness and lock. Something probably shorted out there and they replaced the lock, the motor and the wiring harness. Then all was fine. A rather expensive repear that wasn't covered by warranty.
Around 1,5 year ago my airbag indicator turned on all the time. It never turned off since then. I tried to take of the power from the battery for a day or so and already cleaned all of the contacts under the seats.
My Fiat dealer first said that there was a defective sensor. But when I asked then to fix it they suddenly said it cannot be fixed and that the problem was caused by a defective ECU....
But a few months ago the rear windscreen wiper started to act weird. It turns on briefly every time I start the car, regardless of if the switch is turned on or not. After a while it stops randomly somewhere on the window. When I do use the switch to control the motor, it always stops immediately and never goes to park.
And as of right now a third issue has been going on for a while where the climate control will pulsate. This means that the air will blow louder and then stop and keep repeating for a while until it begins to work in a steady way. Really annoying
The things I tried:
I couldn't connect to the ECU and other components, but I did manage to perform a readout. The weird thing is that even with the colored cables from AliExpress, I can't get the connection to the modules to work in Multiscan.
I got the following error codes:
Any tips on why I can't connect to Multiscan when I use the colored cables with the ODB reader I mentioned? If I need a different ELM327 cable then suggestions are welcome.
Thanks!

The things I tried:
- A full reset by shorting the battery terminals didn't solve anything
- I already checked all the fuses and relays, couldn't find anything
- I visually inspected the windscreen wiper engine and cables. couldn't see anything off
