Solution

1. Preparation

Tools Required: None specifically for this step.
Ensure the vehicle is parked safely with the ignition in the 'On' position.
Disconnect any accessories that may draw power from the battery.

2. Restart the Touchscreen

Locate the two scroll wheels on the steering wheel.
Press and hold both scroll wheels simultaneously for approximately 10-15 seconds.
Release the scroll wheels when the Tesla logo appears on the screen.

3. Check Software Update

Navigate to the 'Software' section of the touchscreen once it is responsive.
If an update is available, follow the on-screen prompts to download and install it.
Ensure the vehicle is connected to Wi-Fi during the update process.

4. Inspect 12V Battery

Open the front trunk (frunk) and locate the 12V battery.
Use a multimeter to check the voltage; it should be around 12.6 volts or higher.
If the voltage is below this level, consider recharging or replacing the 12V battery.

5. Perform Factory Reset (if necessary)

If the touchscreen is still unresponsive, a factory reset may be needed.
Navigate to ‘Settings’ > ‘Service’ > ‘Factory Reset’ if the touchscreen becomes responsive.
Confirm the reset and allow the system to restart.
