Solution

1. Preparation

Ensure the vehicle is parked in a safe environment.
Disconnect the charging cable if it is connected.
Gather tools: multimeter, cleaning supplies (soft cloth, isopropyl alcohol), and a replacement charging cable if necessary.

2. Inspect and Clean Charging Port

Open the vehicle's charging port.
Use a soft cloth and isopropyl alcohol to clean the contacts inside the charging port.
Ensure there is no debris obstructing the port.

3. Test Charging Cable

Use a multimeter to check the continuity of the charging cable.
If the cable shows any signs of damage or does not pass the continuity test, replace the charging cable.

4. Check and Reset Charging Station

If using a home charging station, inspect the circuit breaker and reset it if necessary.
For public charging stations, try connecting to another station to rule out issues with the original station.

5. Software Reset

Press and hold the brake pedal and the two scroll wheels on the steering wheel until the touchscreen turns off and the Tesla logo appears.
Release the buttons to complete the reset.
