Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Socket set (for fuse replacement)
- Torx screwdriver set
Verify that the vehicle is in a safe environment and parked on a flat surface.

2. Battery Voltage Check

Connect the multimeter to the battery terminals.
Measure the voltage and ensure it is within the recommended range.
If the voltage is low, charge or replace the battery as necessary.

3. Fuse Inspection and Replacement

Locate the fuse box in the trunk and remove the cover.
Use the fuse diagram to find the infotainment system fuse (F57).
Pull the fuse using a fuse puller and inspect it visually. If the metal strip is broken or burnt, replace it with a new fuse of the same amperage.
Reinstall the fuse and cover the fuse box.

4. Hard Reset of Infotainment System

Disconnect the negative terminal of the vehicle's battery using a socket set.
Wait at least 10 minutes to ensure all systems are fully discharged.
Reconnect the negative terminal and ensure it is secure.

5. Wiring Inspection

Remove the infotainment system display using a Torx screwdriver to access the mounting points.
Carefully inspect the wiring harness connections at the back of the display for any looseness or damage.
Reconnect any loose connectors and ensure all wiring is intact.

6. Error Code Check

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Scan for any error codes related to the infotainment system.
If codes are present, refer to the specific error code for further troubleshooting.
