Sorry. Small keys.
2019 Sprinters have a small 5 amp gell battery under drivers seat. A coworker unplugged the airbag connector on the drivers seat with disconnectiing all battery's. That triggered the airbag mil on dash. All power on Sprinters must be disconnected or this seems to happen. My MK808BT won't clear the code. Fords Cargo Vans will self correct but not Sprinters when all connections are made right.
