How would I know the trouble code? I know that the dealer tells me each time that I must not keep stuff uder the seats and I have to tell him time & time again that I DO NOT. They mentioned that they read a high resistance, found a frayed wire, they re-routed the harness under the seat sometimes it was the passanger side and other times the drivers side. The last time, the factory rep allowed them to change the wiring harness and the back of the drivers seat. This was the longest period before the light came on now. About a month ago it stayed on for a day a few times it came on but went off after a restart of the engine.

Three dealers have worked on this problem over the years. Could it be a computer problem? I asked if they have seen this problem before and their answer is no. I would think that Hyundai could track, through their database, a problem like this and have a solution. What do I ask for now when I return to the dealer? I've talk with Hyundai on 2 occasions in the past. Thanks for your help and advice

John: I think you've given me enough information here. If the dealer
tells you each time to not put items under the seat, then we're most
likely dealing with the codes for high side air bag resistance.

The part about not hearing of it before is pure BS. There was recall on
this issue. That doesn't mean that Hyundai is required to fix your
vehicle for free for forever whenever the air bag light comes on, but it
does mean that Hyundai *is required* at no charge to you to perform those
repairs outlined in the bulletin (one time). If this doesn't properly fix
the vehicles, then it's the job of the NHTSA to require additional recall
work.

I see numerous vehicles which haven't had the recall done properly. The
issue is that the harnesses under the seat move around and the small
movement of the terminals in the connectors causes an intermittent high
resistance issue. In almost every case where I've routed the wiring and
secured as per the recall bulletin, the problem has never come back (to my
knowledge). So, my initial suspicion is that the recall was not done
properly.

Here's what I'd do:
First, get an account at www.hmaservice.com if you haven't already done
so, and see if you can access the TSB for the air bag wiring recall (I'm
not sure if you can).
Then, if you can operate a socket wrench, remove the four 14mm bolts
holding each seat down and tip them back so you can see the wiring really
well. If the wiring isn't exactly as it should be, as described in the
bulletin (lots of pictures), then you should contact Hyundai immediately
and tell them what you've found and that you demand that they arrange to
have the recall properly performed. If you want, you could even call
NHTSA for them to investigate. I think you'll find Hyundai very
responsive if there's any doubt on their part that the recall was
performed properly.

If everything appears proper, then I have little to offer other than
returning to the dealer for diagnosis and repair.

Sorry about the disjointed reply.

As far as knowing what the codes were, you'll have access to that as long
as the dealer tells you. It's something they need to document for Hyundai
to reimburse them fully. In most cases, the dealer will document the codes
on the customer copy of the receipt.

While I don't think you should be required to not keep things under the
seat-- the vehicle *should* be well enough designed that this isn't an
issue unless things are literally *crammed* under there-- you are
nonetheless in the situation where this can aggravate a problem with the
connectors, so I recommend it just so you won't have any unnecessary
problems (hopefully).
