Possible Causes
Failed RFID reader module, Damaged RFID antenna, Loose ribbon cable between RFID board and main board, Firmware configuration disabling RFID
How to Fix / Troubleshooting
Safety: RFID faults are low‑voltage but still require power isolation before opening the unit.
- Test multiple cards: Try more than one known‑good RFID card or tag to rule out a card issue.
- Check access settings: In the EVBox app/portal, verify that RFID authentication is enabled and that the cards are registered.
- Power cycle: Turn the charger off and on to reset the RFID module.
- Inspect RFID module (qualified): With power off, remove the front cover and locate the RFID reader board behind the front panel. Ensure its connector to the main board is secure and that the antenna area is not physically damaged.
- Replace RFID module: If E018 persists, replace the RFID reader board with an EVBox‑approved replacement.
