Not sure if I'm posting this in the right spot... My check engine light came on today leaving work. So I went back to the shop to use my snap on scanner to look up the code... I couldn't get the scanner to work. I kept saying it had no communication with my truck... I did notice that usually when I hook that scanner into an obd2 port it comes on but I was having to turn the scanner on manually... I assumed the scanner messed up somehow and The truck runs and sounds fine so I assumed it was a sensor of some kind so I went to oreillys to have them pull the code and ran into the same problem... It's a 2001 silverado 5.3 I put a newer 5.3 engine, cam, long tubes and mail order tune from Nelson in may and its been running fine no problems... Any ideas?

I only see an aux 20a fuse no cig fuse and its good. My truck has three aux ports inside well I guess two aux and one cig in a row... My radar detector is in one phone charger in another and nothing in the third both of those work but I plugged my charger into the third and it didn't come on... But shouldn't all three be on the same fuse
