Airbag light

[Guest]

When I first start my car (94 C2), the airbag warning light takes up to 1 minute to go off. I asked my Porsche specialist about this, and they said that as long as it goes off then it is OK? Does this sound like something simple like a sensor, or should I just live with it? Grateful for any suggestions.

hi
Has someone disconected the passenger side airbag and fitted a resistor kit, on some cars when you do this the light flashes for a while when you turn on the ignition to alert you to this fact. It usually alters the behaviour of the lamp when you electronically inhibit the passenger airbag (for rearward facing child seats),this is normally done by recoding the control unit.I would get the circuits checked out because one minute is far too long for the light to be on under normal circumstances.
this may be of some use.
p.s the contol unit is only approx £200 plus vat and fitting ,which is easy.

Thanks so much for the advice, I will get the electronics checked out ASAP,

Yep, thanks Maurice, trouble is this may not be false, because I have had a RS wheel fitted and the system fooling resistor, so before I start tearing into that area I need to get the system interogated to make sure its not a seatbelt tensioner or something simple. It does seem that the Hammer is the only foolproof test though?

Personally I'd first look at the resistor to see if that's not disconnected slightly, gone phut or too low a rating.
If the airbag light was staying off correctly earlier with the new RS wheel, then the resistor's a strong contender that, at the very least, needs to be eliminated from enquiries !

When you say they "could not reset" it, do you mean they did not have right device to plug in to a 993, or that they do have tool but the airbag fault refused to reset? If refusing to reset I assume you have tried a complete battery disconnect (use key to switch of alarm siren first), leave for a couple of minutes, reconnect. It might be that the really low battery put the airbag sensor into some fault state.

...I couldn't even jump start . I took it to an independent and awaiting verdict as he couldn't reset it. Anyone got any ideas as to best way forward ? Michael

Get a lift ? []

Forgive my sense of humour.
Seriously, though, in my experience I found when mine went completely flat (radio drained it) that it needed 30 mins or more with the battery disconnected before any odd lamps showing incorrectly were cleared out of the ECU memory and able to restart car.

Eveything functioned normally from that point on and I replaced the battery to boot, as it had suffered badly.

mine is on as well, but this is after a steering wheel delete, the fooling fix worked for nearly a year but the light is on now, must get it fixed before the MOT. Not all non hammer devices can read all of the faults that can occur, you may end up at your local PC for a fix

I would have thought that the tester would be more concerned about the lack of steering wheel than the air bag light being on []

yes..........very witty, ok as I am sure you knew I was talking about an airbag equipped steering wheel !

Yes, I'd say get the fooling fix replaced (little resistor or whatever it was ) as you can't even pull the offending lamp and then go in for the test.

It needs to be seen working when you turn on the ignition, and go out once it is started.

(Or put your old steering wheel on just for the test, if all else fails or yuo're feeling lazy [] ).
