"Service Side Detection System" warning in GM cars

If you see the warning “Service Side Detection System” in your General Motors vehicle, it may mean that the blind-spot monitoring system radars behind the rear bumper are not feeling well. They may be knocked out of alignment, corroded, disconnected, or they also may have poor programming. First of all, pay attention to the TSB PIT5622B issued in 2020. It covers radar problems and may help you investigate the issue before you go to the dealership and pay your money for inspections. Also, for the 2013-2014 GMC models, the problem is very likely with the corroded radars and connectors and they have to be replaced. I hope this video helps you solve the problem. Also, if you have experience fixing this issue, please share it in the comments. You will help a lot of GM vehicle owners to solve the problem without investing thousands in it.
