Solution

1. Preparation

Ensure the vehicle is in a safe location and turned off.
Gather necessary tools such as a trim removal tool and a socket set.

2. Perform a Hard Reset

Hold both scroll wheels on the steering wheel until the Tesla logo appears.
Wait for the system to reboot, which may take a couple of minutes.

3. Check Software Updates

Connect the vehicle to a Wi-Fi network.
Access the 'Software' menu from the touchscreen (if responsive) to check for any available updates.
Follow the prompts to install any updates and wait for completion.

4. Inspect and Clean Touchscreen

Carefully remove any trim surrounding the touchscreen using a trim removal tool.
Inspect for any physical damage or signs of moisture.
If necessary, clean the screen with a microfiber cloth and appropriate screen cleaner.

5. Verify 12V Battery

Open the front trunk and locate the 12V battery.
Use a multimeter to check the voltage; it should be around 12.6V when fully charged.
If the voltage is low, replace the 12V battery.

6. Reconnect Main Battery

Turn off the vehicle and disconnect the main battery (high voltage battery) by removing the fuse or terminal.
Wait at least 10 minutes before reconnecting to allow the systems to reset.
Reconnect the battery and check if the touchscreen functions properly.
