Technical Warning Light on Dash: HELP

[Richard09]

Hi There,
I have a Grande Punto 1.2 Active, on an 07 plate.
After disconnecting the battery to wire a sub&amp, then reconnecting, and then starting up the car, there is what appears to be an airbag warning light
Whether or not this is the passenger/drivers airbag i don't know..
But the warning light is a little man sitting in a seat, with a large circle hovering above his legs.
This warning light is red.
Any thoughts?
Time to contact Fiat in my opinion..
Is this a common fault?
Thanks,
Richard.

Its not a fault, you've caused it yourself by disconnecting the battery.

Just needs the airbag system reset. Either the dealer or an autospark with an Examiner clone will extract money from you.

No, the GP has a more intelligent system than that. Its more likely that a cable to the airbag system was knocked while he was installing the sub and amp. Id suggest you re-trace your steps for your installation, making sure you havn't damaged any wiring.

First time I've ever heard the term 'intelligent' used with a GM product.

However, I bow to your greater knowledge.

lol, maybe intelligent isnt the right word

The CAN network checks for errors everytime it starts up, and automatically refreshes the system so theres no need for this "switching off warning lights". If theres no problem, it will reset itself. Hopefully.

Silly me, was thinking analogue not digital.

Therefore any change in resistance of a wire will flag up the fault. Hope the OP didn't have his soldering iron out.

Whereabouts are the airbag wires located?
Surely not the back of the Head Unit ?!

Eh, let me think where the airbags are. Oh yes, either side of the dash.

Yup, there will be airbag wiring under the dash, near the head unit.

So please tell me that two wires connected to the HU labled "Can A" and "Can B" are NOT airbag wires?

Maybes aye, maybes naw, a tech will be along in a minute.

However, they are digital wires.

If you have attached anything to them you'll need a new loom.

They arent, but when pulling the wires out for the HU you may have caught the airbag ones in the dash. Maybe something as simple as pulling it out a plug slighty. Either way you will need to get it on diagnostics to get it reset as while the light is on the airbags dont work.

The light will go out itself when the faults fixed

 

[punto_matt]

It stays on and will be logged on the system. As far as the cars concerned it thinks there is a problem. Its not like if the EML comes on where it resets itself if you turn it on or off however many times without the fault reoccuring. If it was just wiring that got knocked then it would of reset itself if nothing was actually wrong.

 

[adamcot]

I meant knocking a wire would damage the connection, or knock a wire out of a connector block.

My Stilo always used to reset the warning after the connection was returned. Haven't had any airbag problems with the GP, but I guess you have so you would know better

 

[punto_matt]

Im going more on experience from mk2s which are similar. If wires were knocked or loose then the light would stay on as it is logged in the system as having a fault on whichever wire has been moved. I maybe wrong though!

 

[adamcot]

I dont think the Mk2 ran a full version of the CAN system, I think it was K Line only. The GP runs a full CAN network, which integrates the airbag ECU. It is constantly checked for faults. Hence why you can be driving along and an error appears, then goes away.

My experience with the Stilo was that dodgy connections in the wiring caused problems. These connector blocks could have been damaged while the power cable was run into the cars interior.
