U0020 DTC Code
I ran a new diagnostic tool I purchased today and it shows that all is well EXCEPT a U0020 Low Speed CAN Communication Bus Performance error. I'm not having much luck locating what this might mean on my 2017 Yukon XL SLT. I'm not experiencing any symptoms that I'm aware of. Might anyone have...- YukonXLMan
