Hi, my 2013 salvage/rebuilt won't close the HV contractors. Screen reads 12v voltage low (it's not) car needs service and pull over safely. It have 40k miles on it since I rebuilt it (minor comedic damage and new radiator) and have had no problems until now. I have never updated the SW and I pulled the SIMS card when I got the car 2.5 years ago. Any direction or info on this would be greatly appreciated. Best I can ascertain from the forums is I lost a contractor but I don't want to carve into the battery until I get advice from those who have been here before, thanks.
