Another Fiat airbag thread. What have i done! (13 Viewers)

[growly_bear]

There are a couple of fuses behind that panel for the mirrors.

My heated ones on the Exsis stopped working, couldn’t find the fuse anywhere.

What a stupid place to put a fuse.

Do you mean this sneaky pair?

I remembered you telling me that fuses were there. So what's the other one for?

Oh and there were some wires which were disconnected too, a brown pair and a blue pair. That'll be another thread unless yours were joined!

No idea I am afraid, I found them by accident after Travelworld’s esteemed £190 an hour mechanics chucked my ultrasonic alarm sensor behind the panel when changing the fuse.

I hope I never find out.

That's shocking. I really hate paying anyone for having a go. A friends brakes have gone spongy on his Transit custom and they want £180 to diagnose the fault, but they can't guarantee it's what they say!

Bit of an update for you MES minds...
Bought MES and cables from Gendan. Fab service and the email about the packing is hilarious. If you know, you know!

Did a body scan to see which modules could be found (with the yellow lead connected). I got this error message

The existing proxy file was this

and the airbag ECU is now not showing. Airbag light out, but doesn't come on when the ignition is initially turned on.


And when I try to connect to the airbag ECU I get this

It seems as though the airbag ECU is not functioning at all. Is there a fuse?

I'm initially going to follow the battery disconnect procedure and then disconnect the airbag ECU, clean the contacts, refit and also make an additional earth for it, and test again.

It's a bit annoying as although a new ECU was fitted a few months ago, it was done by the previous owner, so there is no guarantee on the parts/work (although I did pay for it to be done as part of the deal!).

Any ideas before I send it to Northernautotech for analysis?

As always, thanks so much for your help

My airbag unit went just because I changed the radio….

sorry to laugh!

t was done by the previous owner, so there is no guarantee on the parts/work (although I did pay for it to be done as part of the deal!).

You could ask the previous owner to complain that it has failed & that you will be bringing it back?
* or you make out you are the previous owner & tell them "your mate "will be returning it?

They can't walk away from a guarantee on the part.Maybe the labour but the part is under guarantee.

I had my airbag unit fail last week whilst we were away and it showed all the same faults yours is showing. Plugging in my diagnostic showed no communication and sending it away for repair showed it has failed completely. I think something had gone a bit iffy as our alarm kept going off, which it has never done before, and the battery voltage was absolutely fine.

I got a new ECU from here for £180 and was told it was a 2024 direct replacement for my 2019 1394332080 ECU. I went to a Fiat Specialist in Sittingbourne today to have it proxi alingned and had a really interesting and lengthy conversation with the technician about CrashData et al, and what can and can't, and should and shouldn't be done with respects to "repairs" and the issues which can occur with regards to configurations, even if the airbag light has been turned off.

Anyway, the unit I bought was confirmed as being a genuine Fiat part, programmed up perfectly with the alignment done and no configuration issues, so ended up really happy.

Bottom line I've taken away from this is there is zero chance I will be using CrashData for any works going forward, and that includes them removing data from your existing ECU and programming a new one, which the tech said should never be done without the ECU in the vehicle as it will not configure correctly, even though it will show as aligned and the airbag light extinguish.
