Charger shows E15 or 'RFID Error'; RFID cards or tags are not recognized; charging authorization fails.

Safety first: Turn OFF power before removing the front cover.

• Test multiple cards: Try more than one authorized RFID card or tag to rule out a single bad card.
• Check reader area: Clean the front panel where the RFID symbol is located. Ensure no metal objects or stickers are covering the reader.
• Inspect RFID module connection: With the cover removed (power OFF), locate the RFID module and ensure its ribbon or plug‑in connector is fully seated on the main board.
• Reconfigure access control: Use the Volvo app or web interface to verify that RFID access is enabled and cards are correctly registered.

If E15 persists and no cards are recognized, the RFID reader module is likely defective and should be replaced with a Volvo‑approved part.
