Solution

1. Preparation

Ensure the vehicle is parked in a safe area.
Gather necessary tools: a wrench for battery terminals and a laptop with Tesla service software if applicable.

2. Perform a Soft Reset

Sit inside the vehicle and ensure it is in park.
Hold down both scroll wheels on the steering wheel until the touchscreen goes black and the Tesla logo appears.
Release the scroll wheels and wait for the system to reboot.

3. Check Software Update

Go to "Controls" > "Software" on the touchscreen.
If an update is available, follow the prompts to download and install it, ensuring the vehicle is parked and connected to Wi-Fi.

4. Inspect and Replace 12V Battery (if necessary)

Tools: Wrench set, multimeter.
Disconnect the negative terminal first, followed by the positive terminal of the 12V battery.
Use a multimeter to check the battery voltage; it should be around 12.6 volts when fully charged.
If the voltage is low, replace the battery with a new one (ensure the replacement matches OEM specifications).
Reconnect the battery terminals (positive first, then negative).

5. Hard Reset

Disconnect the vehicle’s 12V battery by removing the negative terminal.
Wait for 5-10 minutes and reconnect the terminal securely.
Start the vehicle and check the infotainment system functionality.
