Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and is powered off.
Disconnect the vehicle from any charging source.

2. Inspect the Charging Port

Use a flashlight to visually check the charging port for debris or damage.
Clean the charging port with a soft, lint-free cloth if dirt is present.
Check for any signs of corrosion or physical damage to the port.

3. Examine the Charging Cable

Inspect the charging cable for any frays, cuts, or exposed wires.
Check the connector at both ends (charging port and wall charger/Supercharger) for damage.
If damaged, replace the charging cable with a new Tesla-approved cable.

4. Test the Charging Port Connections

Remove the rear panel or access cover to reach the charging port's wiring harness.
Use a multimeter to check for voltage at the charging port's connector.
- If no voltage is detected, trace the wiring back to the battery management system.
Ensure all connections are secure and undamaged.

5. Update Software

Check for any pending software updates via the vehicle's touchscreen.
Follow the prompts to install any available updates, as these may resolve software-related charging issues.

6. Reassemble and Secure

Reattach any panels or covers that were removed during inspection.
Ensure all tools are removed from the work area.
