i need help. My main battery signal (red) on dash board came on yesterday.
I barely made it home. I purchase a new battery of the same specs from autozone to replace it. My car turns on but the red warning sign does not go away.
Do i need to reset the ecu. How do I do that.

I also don't know if I need to replace the aux battery I'm not sure where is it. Or if I need radio codes I need instructions. Need help.
Would like to do it myself and avoid going to a shop.

Thanks.

its not charging, check alternator fuse, check voltage out of alternator at stud, if greater than the battery there might be a bad inline fuse. or your alternator is shot and needs replaced. battery is for engine off, car runs on alternator when running. hope that helps
