Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the parking brake engaged.
Gather necessary tools: socket wrench for battery terminal, gloves, and a multimeter for testing.

2. Disconnect the 12V Battery

Locate the 12V battery, typically found in the front trunk area.
Using a socket wrench, loosen the nut on the negative terminal (black).
Carefully remove the negative cable from the terminal, ensuring it does not touch any metal surfaces.

3. Wait for System Reset

Allow the vehicle to sit without power for at least 10 minutes. This ensures all systems reset and any stored charge dissipates.

4. Reconnect the Battery

Reattach the negative cable to the terminal, ensuring it is seated properly.
Tighten the nut securely with a socket wrench to prevent any loose connections.

5. Check System Functionality

Start the vehicle and check the dashboard for any alerts or warning lights.
If necessary, use a multimeter to verify the voltage of the 12V battery (should be around 12.6V when fully charged).

6. Monitor Performance

Drive the vehicle for a short distance to ensure the battery management system is functioning correctly.
Observe for any abnormalities in charging or battery usage.
