Solution

1. Preparation

Ensure the vehicle is parked and powered on for troubleshooting.
Gather necessary tools: OBD-II scanner (if applicable), multimeter, and a computer with internet access.

2. Software Update

Navigate to the "Software" tab in the settings menu.
If an update is available, follow the prompts to download and install the latest software.
Allow the vehicle to complete the update, which may take several minutes.

3. Soft Reboot

With the vehicle in "Park", press and hold both scroll wheels on the steering wheel simultaneously.
Hold until the screen goes dark and the Tesla logo appears, then release the scroll wheels.
Wait for the system to reboot completely.

4. 12V Battery Check

Using a multimeter, measure the voltage of the 12V battery.
If the voltage is below 12.4V, consider replacing the 12V battery.
To replace, disconnect the negative terminal first, then the positive terminal, and follow the manufacturer's instructions for battery replacement.

5. Internet Connectivity

Check the Wi-Fi connection status in the settings.
If using LTE, ensure that the vehicle is in an area with good cellular coverage.
Restart the Wi-Fi router if connected to home Wi-Fi, or toggle the Wi-Fi setting off and on.

6. Clear Vehicle Logs

If error messages persist, use the Tesla service tools to access the vehicle logs.
Identify any persistent issues and report them to Tesla service for further analysis.
