Technical STOP Braking system faulty
Does it fail again?
Worth uncoupling the brake switch up the top of the pedal..

Hi, I seem to be facing the exact same problem. Have been struggling with it on and off for a week or so but no luck, so far. Did you find any solution?
I never found a solution and was forced to scrap the car in the end, it had only done 75k miles

Sad to hear it didnt work out.
Maybe I should add. In my case, I went to work, picked kids up from school on friday, the car was working fine. Came out next morning to go and do some extra hours at work. Car wouldnt start. STOP light in red on dashboard and ”Braking system faulty” on display, after a few seconds followed by ”Airbag or pretensioner seat belt faulty”. Been charging battery over night (2 months old) been checking fuses and the grounding points I could find. I cleaned the bracket where the minus cable from the battery is grounded onto the chassi and noticed that cable looked a bit rusty/corroded but seemed minor. Been trying to check for codes with a ELM327 but it cannot connect to ECU. Dont know if this i a common problem with fiat or not but the ELM is working fine on three other cars I tried. Two Volvos and a KIA.

Anyway I’ll keep posting info on how its going with mine in case someone else might find it usefull. Sunday evening, after an hour or so with alot of rain, there was a squeeking sound from the engine compartment. It wouldnt stop until I took the battery-plus off. I’ve narrowed it down to it being the washer fluid pump going constantly. Something obviously happened or ”got contact” as the humidity increased outdoors. My mechanic couldnt get his computer connected to the ECU either so he will look further into that component to start with. As we cannot get any codes its hard to know where to begin if I was to do it myself.
I'd start with cleaning checking and reinserting all the fuses and main power connectors
The fact you can can't to any of the ECUs sounds likes something important has lost power or computer/can lines between different computers have lost connection
Check the wiring loom for any visible damage
Any sign of corrosion on any of the pins or bare copper showing on the cables especially the abs and or airbag ECUs
Is there power the the brake light switch brake fluid sensor in the resivour
Check cables going to the abs sensor's and pad warning sensor for damage
