Airbag ECU woes

And onto the next problem. 2012 1.2 lounge airbag ECU removed was the message in MES. Airbag lights up on dash as well as others.

Got second hand ECU, fitted. Car sees it but Iíve got three errors throwing up which wonít clear.

Passenger airbag exclusion light. If I try to switch the airbag on at the Speedo it stays off.

Incorrect configuration. No idea on this. Proxy alignment fails with out of range error.

Driver airbag resistance (second stage). I have seen this before and seems to be the clock spring/squib.

Mileage is still flashing as the proxy alignment wonít work.

I have noticed that the Speedo has got the feint light fault so that probably needs changing so Iím wondering whether this has anything to do with it?

Will be changing Speedo and clock spring next week.

Thoughts?

Airbag ECU woes

Nobody had any thoughts but this is still ongoing.

Changed speedo today, no effect. Changed clock spring, it then got rid of everything but the passenger airbag switch light error. Then drivers airbag (first stage) came up.

The incorrect configuration seems to have gone.

Nightmare. Itís beaten me, first time ever. Iím at a loss as to whatís causing it. The only thing I can think of is the passenger airbag has a fault or one of the plugs is faulty. Not sure whether you can change the passenger airbag from underneath the dash when taking out the shelf or whether the whole dash needs to come out.

The owner is taking it to Fiat to get them to do diagnostics so it will be interesting to see what they say.

Re: Airbag ECU woes

You could try an extension cable (homemade) and link the car to another Fiat's passenger airbag before trying to dismantle the whole dash.

Strangely enough I have but as it's not my car, I've already spent loads of time on it for free (I'm too kind) and don't want to do all that if it's not even that.

Bit too far to be honest. There is a garage Iíve used locally before when I was beaten. My mistake this wasnít the first time. They had the car two weeks and worked on it on and off but eventually got to the bottom of my throttle fault. I use mobile mechanic and Mr Clutch for most things including mot. A lot of people slag off mr Clutch but theyíve been really good with me.

Guess they all come down to the local branch

Hell I was shocked when I go two tyres from kwickfit ( cheeper price by about £30) and they made no attempt to upsell anything

On my Mazda they basically said we've passed it but it should have failed or was borderline to say the least knowing I'd fix it in the very near future, which I did.

Re: Airbag ECU woes

Letst take from begin.

Before the change Ecu u have that erors ?
