Thanks Joe. That's the one. To save the problem of dead links for future readers of this, look in ebay for; "3 Pin to 16 Pin OBD2 Adapter Connector Diagnostic Cable Lead Wire for Fiat" Hope that helps others.

Loc: Isle of Wight,
With great relief I can now say my air bag system is reset and the light is out, and the MoT is done. But it was not from the cables and software recommended on this forum. After showing the garage the correct ecu port they were able to talk to the ecu with their machine, which is a 'Snap-On Modus Ultra' but with using leads from their previous diagnostic machine, a Solus Probe (the engineer thinks that the Solus Probe would have worked too, but cannot confirm that). This is great because I tried to download the trw2scan and was told a FTD2XX.dll file was missing and I thought "Here we go", round and round trying to get the software downloaded, but the garage phoned today and told me the good news. Perhaps the cables I have bought will be useful for other diagnostic work later.

So the conclusion, your local garage can reset your air bag if they have the right machine and know the correct ecu port to enter.

Remember, the light not going out is an MoT failure, so get it fixed or, If you're happy for the air bag to be disabled, remove the bulb remove before putting the car in for MoT (You can't take it out after an initial fail as the tester knows the air bag is not funtioning, if there is no light in the first instance then he can't know there is warning system at all).

Love and pace to all.

Well done Andrew, the cables recommended would rest it but like yourself I use a more modern Modus unit with older cables.

Simply unplugging the connector from the Airbag ECU which is bolted to the transmission tunnel, behind the centre console, is far quicker than removing bulbs from the dash.

Loc: Isle of Wight,
I did quite a bit of rooting around looking for the correct port but I didn't see the ecu itself (or if I did I didn't realise it), so if anyone has a photo of it that might be handy.

So now I have cables to tap into the ecu (not just the airbag ecu but also other systems I presume as all the ecu ports seem to be the same) what other uses might they come in useful for?

btw, the air-con is now working after some 5 years or so without it. Yipee! It only needed a new condensing rad and dryer! I had to turn it off on the way home from getting it charged as it was too cold!

The airbag ECU is bolted to the central raised part of the floor underneath the heater / centre console. If you have "plus" carpet extensions, the ECU, cabling and diagnostic socket will be hidden. Otherwise, all that stuff is easy to locate when looking from the passenger foot well.

Just look for the cables with a yellow sleeve. This pic shows the cables/sleeve, and shows the paper label still attached referring to "EURO-BAG" (and "CRASH SENSOR" on the ECU) as a clue. Here's a clearer pic of the ECU and diagnostic socket (lower left, it plugs into a dummy connector attached to a metal bracket).
