obd II port no communication, tested port ideas ? can't get through emissions !
About to get plates yanked if i dont get this fixed.
00 Trans am no communication with dlc using my launch scanner , emissions station count not communicate as well.
tried my scanner on 2 other cars to verify it works perfect.
I tested the port I have steady 12v power on orange wire,
I tested ground continuity on the 2 ground ports both check ok,
I removed pcm plug and tested data line from port to pcm and have continuity. tried with key on, tried with car running,
yes cig lighter works , yes I checked all fuses.
any ideas would be fantastic.. my brain is saying ecm not putting out data but car runs fine. searched old post without luck
