P0DFD Battery Charger Coolant Control Valve Control Circuit/Open
The battery charger coolant control valve reports a control circuit/open condition. The on-board charger negotiates voltage, current and safety with the EVSE; a fault interrupts charging or limits it to AC slow-charge despite a DC fast charger being attached.
Is it safe to drive with P0DFD?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
