Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, basic hand tools.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check Battery Voltage

Use a multimeter to measure the voltage at the battery terminals.
Ensure the voltage is between 12.4V and 12.7V for proper operation.

3. Inspect Infotainment System Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the fuse for the infotainment system using the fuse diagram.
Remove the fuse using a fuse puller and check for continuity with a multimeter.
Replace the fuse if it is blown with the same amperage rating.

4. Reset the Infotainment System

If the screen is unresponsive, perform a soft reset by pressing and holding the power button for about 10 seconds until the screen powers off and restarts.

5. Verify Connections

Remove the infotainment unit from the dashboard using appropriate hand tools.
Check all wiring harness connections for loose or damaged wires.
Ensure that all connectors are securely attached to the infotainment unit.

6. Reassemble and Test

Reinstall the infotainment unit and reattach any trim pieces.
Reconnect the battery and check if the infotainment system is operational.
