Solution

1. Preparation

Gather tools including a multimeter, OBD-II scanner, and a basic socket set.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Fuse Inspection

Locate the fuse box (typically in the driver's side footwell or under the hood).
Remove the cover and check the diagram for the audio system fuse.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Battery Check

Use a multimeter to check the voltage of the battery.
If the voltage is low, jump-start the vehicle or replace the battery if necessary.

4. Wiring Inspection

Remove the radio unit from the dashboard by gently prying it out using a trim removal tool.
Inspect the wiring harness for any loose connections or damage.
Reconnect any loose wires and replace damaged wiring as needed.

5. System Reset

With the ignition on, attempt to reset the audio system by disconnecting the battery for approximately 10 minutes.
Reconnect the battery, then check if the radio powers on.
