Solution

1. Preparation

Ensure the vehicle is parked in a safe location and the charging station is accessible.
Gather necessary tools and equipment: a clean cloth for the charging port, a multimeter, and access to a different charging station, if needed.

2. Inspect Charging Cable

Remove the charging cable from the vehicle and inspect it for any signs of damage (cracks, frays).
Clean the connectors at both ends with a dry cloth.
If damaged, replace the charging cable with a new one.

3. Clean Charging Port

Use a clean, dry cloth to gently wipe the charging port and ensure there are no obstructions.
Inspect the charging port for bent pins or foreign objects; if present, carefully remove them.
Ensure the charging port is dry before attempting to reconnect the charging cable.

4. Test Charging Station

Plug the charging cable into a different known-working charging station or Supercharger.
If the vehicle charges normally, the original charging station may be malfunctioning.
If the issue persists, proceed to the next step.

5. Software Update

Check for software updates via the Tesla touchscreen by navigating to ‘Software’ in the settings menu.
If an update is available, follow on-screen prompts to install it.
Ensure the vehicle remains connected to Wi-Fi during the update process.

6. Reset Systems

Perform a hard reset by holding down both scroll wheels on the steering wheel until the touchscreen turns off and then back on.
After the reset, attempt to charge the vehicle again.
