A couple days ago I had a fuse issue. So I knew the fuse was blown. I went to repair the fuse that I saw was blown swapped it out and then got back in my truck and started driving. Well I noticed lights on dashboard dim and all needles not moving on 0. Went to plug my obd2 scanner and got 2 codes saying not able to communicate data from bcm and ecm. Checked the pins and pin 16 getting no power. But pin 6 and 14 got 60 v. Any ideas?? Thanks in advance for helping me get this issue resolved! Appreciate your Generosity and time out of your day to give me some advice!

Should be a 6 rib 13/16" on your truck...I believe. I'm having same issue with my new high output alternator and finding a serpentine belt for a 14 silverado but I need one about 70 in 6 rib 13/16"

Yeah I'm thinking it's a short... just don't know where to really start on finding it so any and all suggestions are welcome! ? thanks in advance for any and all help!

I was getting code from obd2 saying bank 2 sensor 1 was bad. So I looked at my live data on my obd2 reader and it showed that it was high voltage and stuck at that number. But after replacing the 02 sensor for bank 2 sensor 1 nothing has changed and the code still reads high and frozen just as before. Is there something I might be missing? Reset or re learn? Thanks for any help in advance.
