Aftermarket seats and airbags


Recommended Posts

Apparently the airbag adjusts it's deployment force based on the weight it perceives in the seat. So what happens when you install an aftermarket seat like a Recaro or an SPG? If you disconnect all of the wiring to the seat, is it possible that the airbag won't even deploy? I have a '99.

There is no weight sensor in the 996. The airbag uses the seat belt buckle to tell if someone is in the seat - that is why you need the special bar and programming when you use a child seat.

So if you disconnect the seat belt buckle you will get an airbag (warning) light -- but the airbag will still deploy on a signal from the trigging unit. (Assuming the airbag itself has not also been disabled).

If you put in a racing seat and racing harness you will need to get a spare belt end to put in the buckle or wire in a resister to simulate the buckle connected.

If you are just driving on the street I suggest you stay with the factory belt/buckle system.

Does this apply to all 996's (I have a 2003 TT)?

Where can spare buckles be had (to plug in on a DE day, I'll revert back from 6pt to 3pt for daily useage)?
