Possible Causes
Faulty RFID reader module in Kia charger, Damaged or incompatible RFID card, Loose connection between RFID reader and main board, Firmware configuration error in access control settings
How to Fix / Troubleshooting
Safety first: This is a low-voltage issue, but still isolate mains power before opening the unit.
- 1. Try another RFID card or tag: If your charger uses RFID, test with a different authorized card to rule out a bad tag.
- 2. Check app settings: If the charger is linked to a Kia app, verify that access control settings are correct and that your card or user is authorized.
- 3. Clean the reader area: Wipe the RFID reader surface with a dry cloth to remove dirt or metallic debris that could interfere with reading.
- 4. Internal connection check (technician): With power off, a technician can verify the wiring or ribbon cable from the RFID reader module to the main control board.
- 5. Replace RFID reader module: If E17 persists and cards are known-good, replace the RFID reader module with a Kia-specified part.
