No Comm on OBDII from NYS Inspection but has 12v and Scantool Works
As the title says I have 12v on the hot pin of the obd ii connector, grounded to both of the grounds (dedicated ground and comm link). In addition i plugged my ELM327 scan tool in and got a reading on everything.
It was a little finicky, some programs wouldn't read it but that could just be because of the compatibility with the scan tool. I reseated the huge connector right near the parking brake cable, same results.
Edit: For clarity, I've brought it to Goodyear Auto Svc as thats the closest shop to me and they insist (two separate visits) that the NYS inspection computer tries three times and then it states no Data communication.
