Service Front Camera

[Will Cofield]

Hi everyone! I cranked my 2020 GMC 2500 Denali yesterday after work and had a message telling me to service my front camera. I turned it off multiple times, and even after getting in it this morning, it's saying the same thing. I went to the cameras in on the dash and I could still see out of all of them on the front and sides, but I noticed that my lane detection was not working and I could not turn it on. That leads me to believe that it's camera behind the rear view mirror that is acting up. I would really like to try and diagnose the problem myself because the dealer is going to charge an arm and a leg. Just checking to see if anyone else has had this happen and what they did to fix it?

You're going to need a pretty good code scanner to even begin to figure out what the issue is.
