Solution

1. Preparation

Tools Required: None specific, but ensure you have access to the Tesla app or a Wi-Fi connection for software updates.
Safety Warnings: Ensure the vehicle is in park and secure before performing any actions.

2. Soft Reset Procedure

Locate the two scroll wheels on the steering wheel.
Press and hold both scroll wheels simultaneously for about 10 seconds until the touchscreen turns off.
Wait for the Tesla logo to appear, indicating the system is rebooting.
Release the scroll wheels once the logo appears.

3. Software Update Check

Access the vehicle settings through the touchscreen (if responsive) or use the Tesla app.
Navigate to the "Software" section and check for any available updates.
If an update is available, connect the vehicle to Wi-Fi and initiate the update process as instructed.

4. 12V Battery Inspection

Open the front trunk (frunk) and locate the 12V battery.
Use a multimeter to measure the voltage output; it should be approximately 12.6 volts or higher for a healthy battery.
