Do you have two batteries? If so, are both good?

Car has two batteries both are good So I disconnected the negative cable and let the car sit for ten minutes and it rebooted the car and car fired right up then I scanned the car it's a bad Sam unit in the trunk I Found out these cars had a faulty seal around tail lights and they leak into spare tire holder where the sam unit is the codes are saying door open fuel Gage goes to empty then back up interior light says faulty apparently this unit can shut car down so I'm ordering one and having my buddy install it thanks for answering this group is awesome I've learned so much reading others issues and the replys
