Technical Control system on steering wheel

[malcolm111]

I had problems with the horn not working through 360 degrees of turning the wheel, the fault was in the mechanism behind the boss / airbag. Needless to say this is all plastic and upon examining it with my fingers it sprang apart, I think I got it back together again apart from one plastic cog which where it goes heavens knows, anyway I put a new steering wheel and boss on the car connected the battery and went to start the car which I did (surprised) as I need to put a starter motor on the car as well once I can fathom out the bolt size, I digress after starting the car the instrument screen goes haywire and says airbag malfunction and a load of gobble goo that I can't say what also the radio control don't work, well none of the buttons on the wheel work, as I know nothing of car electric or car ecu can anyone give some advice other than scrap this 2008 fiat Grande Punto

You haven't connected the cables correctly or the clock spring is broken.

The cables can only be connected one way and not interchangeable, what clock spring?

 

[SRafferty]

It's the cable inside the plastic hub around the steering column just behind the steering wheel. The indicator and wiper stalks are connected to it. The wires inside the cable can work harden and fail over years of turning the steering wheel. Not too difficult to replace. You should be able to pick one up on eBay. OE expensive.

I'd be surprised if it's different from the one in the 500 / Tipo etc. So if you can pick one of those up more readily you could try it. Just make sure who ever you get it from will accept a return before you buy.

I'm just waiting for a reply from a fiat dealer how much they are

Punto controls are GM family, rather than FIAT family, so they will be different. However that still leaves the MiTo and the ubiquitous Corsa to raid parts from.

 

[SRafferty]

The stalks are the same design though, aren't they. Anyhow I could be wrong.

No, very different to "pure" FIATs of the same era. My ex had 2 Grande's, I've got a MiTo currently and have owned various other Puntos, my wife has a 500. The 500 shares the same stalks that the old Punto Mk2b had.

Good to know. Thanks

Ordered one from fiat they are £114 which being the first major expense on the car in 10 years, so it’s cheap motoring, it has to come from Italy it’s not a stock item

Hi Malcolm, have you ordered the cruise control version ?

BRs, Bernie

 

[AndyRKett]

Hopefully you’re not using the car at the moment, the risk of the airbag now being incorrectly wired in seems high and in the wrong situation depending on how it’s now wired could deploy.

I’d take it apart again till the new piece turns up or at least disconnect the car batter.

I haven't ordered any yet due to having a new price of £257

No not using the car and the battery is disconnected

Do you know if the one without cruise control will work on the car without having any adverse effects, because the £200 difference I can make do without cruise control

 

[Bernievarian]

The "simple" indicators/lights stalk uses the same pinout as the "CC" one, though it uses 2 wires less. For cleanliness, I'd deactivate the cruise control function in the BCM...
