I might have found my issue. So I noticed that my negative terminal cable is loose on the rear battery. When I went to tighten the bolt on I also noticed that the nut is stripped which I never noticed so the negative terminal isnt on secure and not making proper connection. Since this is the ground cable where does this cable connect to the car? I been looking for a picture of where it’s mounted to on the car. Part I am talking about is 2215407710. This cable might be why I am having terminal 30 under voltage issues. Any pictures of there this cable mounts to before I start taking apart my trunk would be great

Awesome thank you.. I hoping this is what’s causing my starting issues cause I was getting under voltage errors and the car wouldn’t start. Both batteries are new and tested as well.

I am getting super frustrated on trying to figure out why my car will start after several attempts and then the next morning I go to try and start and no go. Battery tested front /rear battery and they are good. Alternator and starter under 2 years old. I get codes of under voltage. Any help would be great. Once started I rescan the car and still get codes. The negative terminal cable clamp is loose and I am going to replace it but I am really tired of this car.

replaced the negative terminal cable and thought it fixed the issue. The car started no issues ..This morning tried to start no good. Scanned the car and got codes for low voltage but checked the batters they are fine. I cleared the codes and the car started right up.. I need to figure out which code gets erased for it to allow it to start up
