Code result
P0EEF
Battery Charger Coupler Temperature B Too High
High severity
What it means
The coupler B temperature exceeds the safety threshold during charging. 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?
No — stop driving
