Solution

1. Preparation

Tools Required: Multimeter, clean cloth, compressed air.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the charging cable from the vehicle and the power source.

2. Inspect and Clean Charging Port

Use compressed air to blow out any debris from the charging port.
Wipe the port with a clean cloth to remove any dirt or residue.
Reconnect the charging cable and check if the issue persists.

3. Test Charging Cable

Use a multimeter to check for continuity in the charging cable.
If the cable is faulty, replace it with a new one.
Ensure connections are secure and not loose.

4. Check Charging Station or Wall Outlet

Test the outlet with a multimeter to confirm it is providing the correct voltage (usually 120V or 240V).
If using a home charging station, ensure it is functioning correctly or reset if necessary.

5. Software Reset

Perform a soft reset of the vehicle by holding down the two scroll wheels on the steering wheel until the screen resets.
After the reset, check if the charging functionality is restored.

6. Consult Tesla Service

If the problem persists, schedule an appointment with Tesla service for a thorough inspection and possible battery management system (BMS) recalibration.
