This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.
Warning
The ISO 15118 (Vehicle-to-Grid) session setup between your vehicle and the charger failed. This protocol handles advanced features like Plug and Charge. A failure here usually means the charger and vehicle could not establish a secure communication session.
What to do
- Unplug and retry. This is often a temporary protocol glitch
- Use RFID or app-based authorization as a fallback
- Try a different charger
- If the issue persists, check for a vehicle software update
Who's responsible?
- This may be a vehicle issue
- This is likely a charger hardware issue
