It’s not the voltage that’s the issue, it’s the state of charge. The truck monitors the amperage being drawn from the battery; once it becomes too low on charge, it starts to shut off various features. For some reason one of them is the passenger side passive entry door handle.So, not sure what the issue is here. Battery is charging at 14 volts, was at 13.4 when I switched the engine off, which I suspect should be more than enough? Start/Stop doesn't work, but then again at -11c (12 Fahrenheit) I wouldn't expect it to. Remote start works too.
On a separate issue, I can't find a carwash wide enough for the Raptor to fit in, and I can't clean it outside in this weather But that is a whole different challenge. This truck really is enormous compared to everything else on the road here in Norway.
As the truck is driven and the battery state of charge increases, the passive entry should start to function again. Alternatively, you could charge the battery with an AGM compatible charger and then perform a Battery Monitoring System Reset using ForScan.
