Possible Causes
Damaged RFID reader module behind front fascia, Loose connection between RFID reader and control PCB, Unsupported or corrupted RFID card, Faulty firmware handling RFID authentication
How to Fix / Troubleshooting
Safety first: RFID faults are functional, not electrical, but still isolate power before removing covers.
- Test with known‑good card/fob: Use an RFID tag that is known to work with the charger. If none work, the reader or control PCB is suspect.
- Check reader area: Inspect the front fascia where the RFID symbol is located. Ensure it is not cracked, water‑damaged, or obstructed by stickers or metal objects.
- Inspect wiring: With power isolated, remove the cover and check the small harness from the RFID reader to the control PCB. Reseat any plug‑in connectors.
- Firmware update: If available, update the charger firmware via the Rolec app or service tool, as some RFID issues are firmware‑related.
- Replace reader module: If wiring and firmware are correct but E12 persists, replace the RFID reader module with a Rolec‑approved part.
