How to Fix / Troubleshooting
Safety first: Turn off power before inspecting the connector or internal wiring.
- Clean connector: Gently clean the Polestar connector pins, especially the small pilot pin, with a dry, non‑abrasive cloth.
- Check cable strain relief: Ensure the cable is not under tension that could stress the connector.
- Test with another vehicle: If another EV charges normally, consult the vehicle manufacturer about firmware updates.
- Service inspection: If multiple vehicles show the same symptom, the pilot signal circuitry on the charger may need professional testing and possible board replacement.
