AWR-fix: 20 pin under hood OBD tweak
https://r.tapatalk.com/shareLink/top...ink_source=app
I jumped the pins in the cap on my wife's 00/07 build and now can access all modules with NT-510 from inside the cabin. I believe I used 24ga wire from an Ethernet cable.
It feels like their is some missing connection in your setup.
I can try to stop by as soon as this weekend to plug in my 510 with and without the 20-pin adapter to confirm if there is a problem with the 530 vs. the 510.
