Seatbelt Airbag Light


Recommended Posts

Seatbelt Airbag Light


I have had an Airbag Light for the last 8 months. I tried all the poor man's remedies like an electrical spray and then drying it with canned air. It worked for a while until I realized that the light will reappear after I had passenger actually use the belt. When I ran the codes using my Durametric Tool I got Fault code 48 which indicated a Passenger Side Seat Belt Problem. The previous owner had the driver's side completed in 2006. Below is a screenshot of the fault code I received:

Are you sure buckle replacement was required or did you just do both wiring & buckle since you were already taking the seat out?

TIA!

Depending on year of the car, fault Codes 45, 46, 48 and 49 refer to a selt belt problem on either the driver's side (45 or 46) or the passenger's side (48 or 49.) The Technical Service Bulletin is TSB 6924. This Bulletin replaces an earlier one dated 10-8-99. I followed the bulletin and replace both. I suppose you can try the buckle first and then the other. SImple enough to go back and do the wiring later.

So I looked through the tutorial and have one question:

If I am just replacing the driver side seat buckle, is it essentially just unbolt old and re-bolt buckle and then plug in the harness wire end?

Excuse the possibly dumb question, but on the tutorial, I see a lot of splicing of wires and grounding of wires etc... and I was under the assumption that the buckle comes with a harness at the end of the wire, thus thinking I just unplug the current one and then plug in the new one.

Can someone decipher for me please?

Thanks!

The early cars (MY1999 to MY2001) had some grounding problems - hence re-making the grounds.

Chances are in your later model car just replacing the buckler will do it. Of course you will still need to reset the airbag light after the new buckle is installed.

Well, the airbag light is on the MY1998 boxster, does that mean I will have to re-make the grounds instead of just "plug-n-play" or just maybe? (dealer said it was driver side buckle code so hopefully this will resolve the after install and reset the light) Inspection is due in a couple months so assume the light will have to be gone to pass...

Thanks!

It would have been nice if you told us the model year ahead of time.

As I said the early cars were problematic for poor ground at the chassis connection under the seat. So if you want to make sure it is fixed for good replace all the buckles (newer ones have gold contacts) and re-make the grounds as outlined in the DIY (and also in the Porsche Service Bulletin).

Is it possible to determine if the repair kit has already been installed? Car is a '99 Carrera. My airbag light is being triggered by the driver's side seat buckle. The image below is the end of the buckle connector under my driver's seat. The wires have clearly been spliced, and to remove the seat completely from the car, I would need to cut the blue and yellow shrink-wrapped wires. Those splices bypass the connector and go directly into the loom.

 


First step is to order some of the DeOxit spray and give everything a good cleaning, but if that fails, do I need a new seatbelt buckle, or the buckle and the repair kit? 


 

Currently the light is off, as a local shop did the read/reset for me. And it has remained off for a few trips since then, though I don't want to drive too much until this is resolved.

 

Thanks!

If the additional grounds have already been done then it comes back to the seat belt buckle. If the TSB has not been done - then it should be. PM me if you need instructions.

Some have cleaned the belt contacts and gotten a couple more years out of them but eventually they will wear out and need replacement.

 Thanks for the reply. I've attached a picture of the ground connection; due the extra wires, can we presume that the TSB has already been completed? If it matters, I have the standard seats with memory seat option but no heat.

99 Boxster.  Does anyone have pictures of how the wiring repair kit needs to be installed/configured?  I have the 000-043-206-06 for the passenger side but it's just wires, heatshrink, plugs and a connector but no instructions on how to install it.  The TSB simply says to put x17 into pin B8.  WTH does that mean?  I am pretty well equipped when it comes to most things but this is just not enough of a description, or visual for that matter, for me to reasonably figure out.

Thanks to @kbrandsma for the awesome tutorial and @Loren for answering a question (on a Saturday!), I successfully performed this fix on my 2000 986 base today. No more airbag light! Took her for a little spin with the top down this evening just to make sure.

 

It was my first job on this new-to-me car. Planning on doing the IMS, clutch, tensioners and chain guides over the winter.

 

[Edit] I forgot to mention that, because my car is a late 2000 vehicle with power seats, the ground wiring didn’t need to be touched (Measure B in the TSB). Lacking a heat gun, I just used a lighter (carefully) for the shrink tubing.
