This article lists fault (F_ _ _ ) and error (E_ _ _ ) codes on these chargers. Most of these will be reported over CAN and logged. Not all will be displayed on chargers with a user interface. If a unit is not functioning and nothing is indicated or logged, check and cycle both AC and DC. If this condition persists, replace the charger.
