The following tables list the ChargeX proposed Minimum Required Error Codes (MRECs), their descriptions and their functional and responsibility classifications.
| Number | Error Code | Fault Code | Description |
| 1. | ConnectorLockFailure | CX001 | Failure to lock or unlock connector on the vehicle side. |
| 2. | GroundFailure | CX002 | Ground fault circuit interrupter has been activated. |
| 3. | HighTemperature | CX003 | High temperature inside the EVSE is derating power delivery. |
| 4. | OverCurrentFailure | CX004 | Over current protection device has tripped. |
| 5. | OverVoltage | CX005 | Input voltage to the vehicle has risen above an acceptable level. |
| 6. | UnderVoltage | CX006 | Input voltage to the vehicle has dropped below an acceptable level. |
| 7. | WeakSignal | CX007 | Wireless communication device reported a weak signal. |
| 8. | EmergencyStop | CX008 | Emergency stop is pressed by the user (required if equipped). |
| 9. | AuthorizationTimeout | CX009 | The user plugs in but fails to authorize a charging session prior to the connection timeout between the vehicle and EVSE. |
| 10. | InvalidVehicleMode | CX010 | The vehicle is in an invalid mode for charging. |
| 11. | CableCheckFailure | CX011 | Failure during the cable check phase. Includes isolation failure |
| 12. | PreChargeFailure | CX012 | The EVSE did not reach the correct pre-charge voltage. |
| 13. | NoInternet | CX013 | The EVSE has no internet connectivity. |
| 14. | PilotFault | CX014 | The control pilot voltage is out of range. |
| 15. | PowerLoss | CX015 | The EVSE is unable to supply any power due to mains failure. |
| 16. | EVContactorFault | CX016 | Contactors fail to open or close on the vehicle side. May also include welding related errors. |
| 17. | EVSEContactorFault | CX017 | Contactors fail to open or close on EVSE’s side. May also include welding related errors. |
| 18. | CableOverTempDerate | CX018 | Temperature of charging cable or connector assembly is too high, resulting in reduced power operation. |
| 19. | CableOverTempStop | CX019 | Temperature of charging cable or connector assembly is too high, resulting in a stopped charging session. |
| 20. | PartialInsertion | CX020 | Cable latch is raised due to incomplete insertion into the vehicle charging port. |
| 21. | CapacitanceFault | CX021 | An Isolation Monitoring Device tripped due to high capacitance during active charging. |
| 22. | ResistanceFault | CX022 | An Isolation Monitoring Device tripped due to low resistance to the chassis during active charging. |
| 23. | ProximityFault | CX023 | The proximity voltage is out of range. |
| 24. | ConnectorVoltageHigh | CX024 | The output voltage of EVSE is high before charging starts or after charging ends. |
| 25. | BrokenLatch | CX025 | The latch on the connector is broken. |
| 26. | CutCable | CX026 | The output cable has been severed from the EVSE. |
