Solution

1. Preparation

Gather necessary tools: OBD-II scanner (if available), cleaning cloth, and a multimeter.
Ensure the vehicle is parked in a safe, dry area.
Disconnect the charging cable from the vehicle and the power source.

2. Inspect and Clean Charging Port

Use a cleaning cloth to clean the charging port carefully.
Inspect the connector for any debris or damage.
If any debris is found, clear it gently to ensure a clean connection.

3. Test Charging Cable

Visually inspect the charging cable for any fraying or damage.
Use a multimeter to check continuity through the charging cable.
- Sub-steps:
  - Set the multimeter to measure resistance.
  - Connect the probes to each end of the cable.
  - A reading close to zero indicates a good cable; high resistance indicates a fault.
Replace the charging cable if any damage is detected or if resistance is high.

4. Verify Charging Station Functionality

Check the charging station's indicator lights to ensure it is operational.
If using a home charger, test the outlet with another device to ensure it is providing power.
If the charging station is faulty, contact the provider for repairs or replacement.

5. Reset Vehicle's Charging System

Power cycle the vehicle completely:
- Press and hold both scroll wheels on the steering wheel until the screen goes black.
- Wait for the Tesla logo to appear before releasing the scroll wheels.
Reconnect the charging cable after the reset and try charging again.
