Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdriver set, socket set).
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Check for Software Updates

Turn the ignition to the "On" position without starting the engine.
Navigate to the settings menu on the dashboard screen.
Select "System Update" and follow the prompts to check for any available updates.
If an update is available, follow the instructions to download and install it.

3. Disconnect and Reconnect the Battery

Open the hood and locate the battery.
Use a socket set to disconnect the negative terminal first, then the positive terminal.
Wait for at least 5 minutes to allow the system to reset.
Reconnect the positive terminal followed by the negative terminal securely.

4. Inspect Fuses

Remove the fuse box cover located under the dashboard or engine compartment.
Locate the fuse for the infotainment system (refer to the owner's manual for the exact location).
Inspect the fuse for continuity; replace it if it is blown with one of the same amperage.

5. Check Connections Behind the Dashboard

Remove the trim panel surrounding the dashboard screen using a trim removal tool.
Unscrew and gently pull out the dashboard screen.
Inspect wiring harnesses for any loose connections or visible damage.
Reconnect any loose connectors and secure the screen back into place.

6. Test Battery Voltage

Use a multimeter to measure the battery voltage.
Ensure the voltage is between 12.4V to 12.7V when the vehicle is off.
If the voltage is low, consider charging the battery or replacing it if it's faulty.
