2006 Impala, battery icon is lit up and display reads Service battery charging system
I have tried looking up the error online and could not find anything. I have replaced the battery. I took it to autozone to be tested and the said the alternator, battery, and starter are good. I replaced the alternator just in case, and nothing changed. I have reset the computer by leaving the battery disconnected for an extended amount of time. Does anyone have any idea of how to go about resolving this issue?
Update: It turns out there was a wire that was not plugged in close to where the positive cable connects to the terminals. The battery icon and message did not disappear right away. It took a couple of hours. I had assumed that plug was from a modded sound system from the previous owner and previously did not notice the loose wire.
