Have a 2015 Toyota Camry

Make sure that the new battery is the right one, with the amps that the car requires. Double check the cables on each terminal to be sure that they are in the right position and well tight. I have seen this happen many times. When the Check Charging System is displayed it is telling you that most likely something is wrong with the battery. And, yes, even if the new battery is the right one, see that each cell has the right amount of water. Many times the auto part gives you a new battery that has been on the shelf for a few months and the cells are very low or dry.

make sure connections are tight and clean

What engine in this vehicle? Why was the battery replaced?

Fixed the prob it was when I bought car the put a kill switch in it and car is paid but they failed to uninstall it so I did

Perfect!
