Get these 2 error codes when i use a durametric to scan for codes.
No airbag light or CEL

POSIP (Porsche supplement impact protection) C152 Communication PSM control unit (drive)

PAS (porsche access system) 8005 Terminal S


I did a lot of searching here for any more info on these but found nothing besides that it could be related to battery replacement, cleared the codes but they come back.

Took bumper off and inspected the front airbag sensors and wiring harness and see nothing out of the ordinary.

Any clue what it could be the issue or how to diagnose it?

 

I had that code when I bought my car, cleared it multiple times with the Durametric and kept coming back. Ended up taking my car to my Indy and he cleared it for me and it hasn't come back since, so might be nothing.

 

did the indy shop clear it with a PIWIS?

 

Could be related to any air bag in the vehicle, including the steering wheel one or the side airbags in the seats. Have you swapped your seats recently - maybe you didn't seat the yellow connector properly under the seat or have you done any work on your steering wheel - installed a different wheel, added paddles, etc. There are also airbags in the door panels - had them off where you disconnected the wiring on them?

 

Previous owner could have. I have not. will check them out, thanks. Seats and steering is easy.
No experience taking the door panels off though.

 

Did you ever find out what this code was for ?
