Solution

1. Preparation

Tools Required:
- Multimeter
- Fuse puller
- OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Battery Voltage

Use the multimeter to check the battery voltage. It should read between 12.4V and 12.7V for a healthy battery.
If the voltage is low, recharge or replace the battery.

3. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify and remove the fuse for the infotainment system using a fuse puller.
Inspect the fuse; if blown, replace it with a new one of the same amperage.

4. Reconnect Wiring Harness

Remove the trim panel surrounding the infotainment unit to access the wiring harness.
Disconnect the wiring harness from the back of the infotainment unit.
Inspect for any damage or corrosion, then reconnect the harness securely.

5. Perform System Reset

With the ignition on (but engine off), press and hold the power button on the infotainment system for 10 seconds.
Release the button and check if the screen powers on.

6. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Check for any error codes related to the infotainment system and address them as necessary.
