Re: peugeot 406 airbag light and ecu

sounding much like they were saying:

By the fact the car's badly bent and there's a couple of limp bedsheets hanging out the steering wheel and dash...

The light doesn't tell you they've gone off. It tells you there's a fault.

If those wires are related to the airbags or pretensioners, yep.

Crap. Unless the passenger airbag was disconnected. If it wasn't, the dead child would be a clue as to any previous airbag deployment.
The airbag light is almost certainly down to damaged wiring under the seats for the seatbelt pretensioners, unless she did have somebody disconnect a passenger side bag.

FWIW, on my 206 the airbag lights occasionally come on complete with warning message. Jiggling the multi-plugs in the area under the steering wheel near the fuses makes it go away for several more months.

You wouldn't be able to miss a blown airbag. If you don't see white powder all over the place and a huge fabric sack sticking out of the steering wheel or dash, they aren't blown. It's not a matter of the components being discharged (that's obvious if it's happened), but whether the control module, squib(s) or related wiring is failing.
Please understand that if you don't know this basic of information, then you are seriously underequipped to diagnose the airbag system fault(s). Therefore I suggest that you take the car to a Peugeot specialist with the proper scanner and experience to tell you what is wrong. I've never even worked on *one* Peugeot product. They stopped selling in the US when I was in middle school, and even then they were rare.
A competent and properly equipped mechanic will tell you what is wrong, how much to fix it, and be able to do it safely so the system works properly in the case of an accident.
I quite agree, airbags are not things to be messing about with if you do not *specifically* know what you are doing.

Nah - they're easy. Disconnect the battery, then put the kettle on. By the time you've sat down and had your cuppa and a natter, the bags are safe.
Even better, you can charge the customer for your tea-break.

This is a very common occurrence on the 406. Under each front seat there is a connection to the seat belt pretensioners. Both mine have gone at different times and, on each occasion, the Pug agent removed the naff connectors and remade the joint with a soldering iron. Been right as ninepence ever since. If someone has tried disabling the airbag system by disconnecting the wires under the front seat then that would certainly cause the warning light. I think you are going to have to get on your hands and knees ;o)

I think the clue is the girl had a baby seat on the passenger seat. Therefore she disconnected the passenger airbag using the switch in the centre console provided for this purpose. This puts the light on as a reminder that the airbag is switched off. All you need do is use the ignition key to switch the airbag back on.

gurgled happily,

In that case, it definitely sounds like the very common under seat wiring problem (see my reply on 10/01/07)

Having said that. BT use Giganews for their usenet service and they have phenomenal retention. I have just scrolled down and the earliest post is 4th July 2003 (yes! 2003) by GT who is talking about a 405GR 4x4 Speedo.
