Solution

1. Preparation

Tools Required: None, but a socket set may be helpful for battery access.
Safety Warnings: Ensure the vehicle is in "Park" mode before performing any resets. Disconnect the main battery only if necessary, and always follow safety protocols when handling electrical systems.

2. Soft Reset the Touchscreen

Sit in the driver's seat with the vehicle in "Park."
Locate the two scroll wheels on the steering wheel.
Press and hold both scroll wheels simultaneously.
Keep holding until the touchscreen goes black and the Tesla logo appears, then release the wheels.
Wait for the system to reboot, which may take a few minutes.

3. Hard Reset (if soft reset fails)

Open the front trunk (frunk) and locate the 12V battery.
Using a socket set, carefully disconnect the negative terminal first, followed by the positive terminal.
Wait for at least 5 minutes to allow residual power to drain from the system.
Reconnect the positive terminal first, followed by the negative terminal.
Close the frunk and check if the dashboard and touchscreen functions have returned to normal.
