Solution

1. Preparation

Gather necessary tools: multimeter, wrench set, battery terminal cleaner.
Ensure the vehicle is in a safe, well-ventilated area.

2. Check and Replace the 12V Battery

Access the 12V Battery:
- Open the front trunk (frunk) and remove any covers to expose the 12V battery.
Disconnect the Battery:
- Use a wrench to disconnect the negative (-) terminal first, followed by the positive (+) terminal.
- Note: Always disconnect the negative terminal first to prevent short circuits.
Test the Battery:
- Connect a multimeter to the battery terminals. A healthy 12V battery should read around 12.6 volts or higher.
- If the voltage is below 12.4 volts, the battery may be weak or dead.
Replace the 12V Battery (if necessary):
- Remove the old battery by unscrewing any securing straps.
- Install the new battery, ensuring the positive (+) terminal is connected first, followed by the negative (-) terminal.
- Secure the battery with the straps and replace any covers.

3. Inspect and Repair Electrical Connections

Clean Battery Terminals:
- Use a battery terminal cleaner to remove any corrosion from the terminals and cables.
Check Wiring and Fuses:
- Inspect wiring for any signs of damage or loose connections.
- Check any related fuses in the fuse box and replace if blown.

4. System Reboot

After replacing the battery and checking connections, perform a system reboot by holding the scroll wheels until the dashboard screen resets.
