Solution

1. Preparation

Ensure the vehicle is parked in a safe area and the charging cable is disconnected.
Gather tools: multimeter, cleaning cloth, and potential replacement parts.
Safety Warning: Disconnect the charging cable before inspecting any components.

2. Inspect Charging Cable

Examine the entire length of the charging cable for any signs of damage or wear.
Clean the connectors with a dry cloth to remove any debris or corrosion.
If damaged, replace the charging cable with a compatible Tesla charging cable.

3. Check Wall Connector

Inspect the wall connector for any visible damage or burnt areas.
Use a multimeter to test the outlet voltage and ensure it meets the required specifications (typically 240V for level 2 charging).
If issues are found, consider replacing the wall connector or consulting a licensed electrician.

4. Reset Charging System

On the vehicle’s touchscreen, navigate to "Controls" > "Safety" > "Power Off" to reset the vehicle’s systems.
Wait for at least 2 minutes before turning the vehicle back on by pressing the brake pedal.

5. Battery Management System

If issues persist, perform a battery recalibration by fully discharging the battery to about 10% and then charging it to 100% without interruption.
Monitor for any unusual temperatures during charging and consult Tesla service if necessary.
