986 Airbag fault codes

[Judi-Driver]

Hi, 

I connected the Durametric scanner since my airbag light ha been on for a while. (I forget we had one)  I cleared the codes but the light came back on.  The codes shown are:

23 Belt tensioner Driver

25 Belt tensioner Passenger

64 Seat Occupancy Detector Passenger

72 Child Seat Detector

 

Can anyone provide any info as to what the issue I need to look at?   I've read that the contacts at the buckle and the plug under the seat can oxidize so I will get some cleaner to spray on them. 

 

Thanks,

Judi

Porsche produced a TSB for this.

Chances are you have bad grounds under the seats and/or worn/dirty seat belt buckles.

 

If the TSB (for the grounds) has been done then likely that your buckles are worn out.

Thank you so much!  I'll check that out.  

 

I hope I didn't err in replying to another post with a similar issue 😯

I've read the TSB and it applies to codes 45, 46, 48, 49.  

 

It reads there was a production change (8/27/99) for Zuffenhausen production from  WP0...YS620308. My car is 620317.  

 

Would the codes still be triggered if the latches were not inserted into the buckles?

 

Thanks, Judi

Yes, or if the seats were removed without disconnecting the battery.

I had a 2001S made in Finland. It had recurring air bag warning lights and I went through the buckle replace, ground replace TSB sequence and it still came back. Then a master mechanic came up with a new technique (the details of which I was never able to find out) and it was fixed finally.

Thanks Mike.  I had been pointed to your website earlier but I don't have codes 45 through 49.
