den dicken kabelbaum kannst außer acht lassen - der is für die sitzverstellung...
ich zitier dir mal das englische coupe-forum:
"I have looked deeper into this and according to wiring diagrams I have found, the seat belt pre-tensioners can not operate the side airbag warning light, so you should only need to do the blue and the single pole red connector.(If it's the side air bag warning light you have!)
Only a fault in either or both side bags in the seat can trigger that warning light.
I can't tell whether the pre-tensioner circuits are capable of triggering the other light (the normal 'Air Bag' light) as their wiring goes through a separate ecu. It could even be that they are not monitored.
This pic shows how the air bag circuits connect to the warning lights.
Side bags in blue
Driver's and passengers air bags in red
Seat belt pre tensioners in brown
The right hand lamp at the top is the side air bag warning light
The left hand one is for the driver and passenger warning light
I did all the connectors before I found this! Since taking out the last, red connector, the light has not returned.
Good luck with the fix."
Hoffe es hilft dir.
