'02 996 Airbag light on with Belt Tensioner Error Code 23

Sorry I can’t help. But Joe, Loren, or Jeff will probably know.  Alternative is a visit to your local stealership for a piwis and wheel removal. Again, good luck.

Judgejon,

Thanks for your honesty. At this point I am convinced it is probably a loose connection somewhere or a bad connector. Offhand do you have any idea what the dealership would charge for the PIWIS test?

Thanks again!

Fault 23 

 

Possible cause of fault:
- Incorrect coding
- Short circuit to B+/ground or open circuit in the wiring between the driver's seat belt tensioner and the control module

 

 

I assume that to test the wiring I just check resistance between the harness at the airbag control module and the harness at the seat belt tensioner? It looks like connector A2 should be the one. Am I missing anything else obvious that should be checked? If there is indeed a break in the connection then can I just run a new pair of wires directly from the harness back to the driver's side belt pretensioner? I have heard that there is some wiring in the steering wheel or is that not related to this?

On thing you are not considering is that the control module itself may be involved.  If that is the case, you are going to need a sharp tech and access to the PIWIS system.

No idea on cost of getting piwis, only that, I believe, it can only be done at a $tealership.

I swapped in another control unit from another car and I still get this error. I am confident I have it isolated to the wiring HOWEVER I suppose it is possible that the other control unit had the same defect.

Sorry to bring up old stuff but I just had the airbag light pop on after a long drive and have read thru this thread in prep for my diagnosis journey.  Were you ever successful in fixing Obin?

 

Thanks!
