Solution

1. Software Update

Ensure the vehicle is connected to Wi-Fi.
Navigate to the ‘Software’ section in the settings menu.
Check for available updates and install if necessary.

2. Battery Inspection

Open the front trunk (frunk).
Use a multimeter to measure the 12V battery voltage; it should read around 12.6 volts or higher.
If the voltage is low, consider replacing the 12V battery.

3. Soft Reset

Sit in the driver's seat with the vehicle in 'Park'.
Press and hold both scroll wheels on the steering wheel until the screen goes black and the Tesla logo appears.
Wait for the screen to reboot and check functionality.

4. Checking Electrical Systems

Turn on the vehicle and activate all electrical components (lights, wipers).
Ensure all systems are operational; if any system is not functioning, further diagnostic may be required.

5. Diagnostic Tool Check

Use an OBD-II scanner compatible with Tesla vehicles.
Connect to the vehicle's diagnostic port and check for any logged error codes.
Document any codes found to assist in further troubleshooting or repair.
