Repair Instructions

Step 1: Performing a Soft Reset

Turn off the engine.
Wait for about 10 minutes.

Step 2: Inspecting and Replacing Fuses

Open the fuse panel cover.
Identify the infotainment system fuse using the diagram provided in the owner’s manual.

On your smartphone, go to Bluetooth settings and forget the vehicle.
Restart both the vehicle and the smartphone.
Pair the devices again following the prompts on both screens.

Step 5: Scanning for Error Codes

Connect the OBD-II scanner to the diagnostic port under the dashboard.
Turn on the ignition (do not start the engine).
Read any stored codes and note them down.
Clear the codes and see if they return after a reset.

Step 6: Additional Troubleshooting

If the above steps do not resolve the issue, consider the following:

Check Connections: Remove the infotainment unit (if accessible) and check for loose wiring or connectors.
Professional Diagnosis: If the system still malfunctions, it may require professional diagnosis and repair, possibly involving replacement of components.
