P2E37 Battery Charger B Enable Circuit High
Battery charger B reports a enable circuit high condition. HV charging operation may be impaired. 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 P2E37?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
