If your battery works fine, this error message is caused by by the auxiliary battery, it’s sitting ahead of the passenger’s seat. Once u replace it this alert clears off. You can find many videos on UA-cam about replacing how to replace it. It’s really easy
Alternator not working. Its supposed to show atleast from 13.50 to 14.50 volts on engine running. Without engine running it goes back to 12.50 volts or somthing....

Yes replaced theain battery. That fixed the problem.
It's the battery, when engine running it shoukd show between 13.7v and 14.7v . In the picture it shows only over 12v
Did you ever fix the problem? If so What was the cause? Same alert just came up for me
Check the battery to see if it’s a bad battery it has to do with the battery if that yellow battery light comes out
