Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the charging cable is disconnected.
Allow the vehicle to cool down if it has been charging for an extended period.

2. Inspect and Clean Charging Port

Use a soft cloth or brush to clean the charging port carefully.
Check for any foreign objects or debris inside the port that may obstruct connection.
Inspect the port for any signs of damage; if damage is found, replacement may be necessary.

3. Test Charging Cable

Inspect the charging cable for frayed wires or damage to the connectors.
Use a multimeter to check for continuity in the charging cable.
If the cable is defective, replace it with an OEM charging cable.

4. Verify Power Source

Use a multimeter to check the voltage at the outlet where the vehicle is charged.
Ensure the outlet is functioning and providing the correct voltage (typically 120V or 240V).
If the outlet is faulty, repair or replace it as necessary.

5. Software Update

Check the vehicle's software version through the settings menu.
If an update is available, connect the vehicle to Wi-Fi and initiate the update.
Follow on-screen instructions to complete the update.

6. Consult Tesla Support

If issues persist after following the above steps, contact Tesla support for further diagnosis.
Provide them with error codes and details of the troubleshooting performed.
