Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wire stripper/crimper.
Disconnect the vehicle's negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, which is typically under the dashboard or in the engine compartment.
Remove the cover and use a fuse puller or pliers to check the fuses related to the radio (refer to the owner's manual for the specific fuse locations).
Replace any blown fuses with new ones of the same amperage.

3. Check Wiring Connections

Remove the head unit from the dashboard using a socket set or appropriate removal tools.
Inspect the wiring harness for any signs of wear, fraying, or loose connections.
Secure any loose wires and replace any damaged wiring using a wire stripper and crimper.

4. Test the Radio Unit

If the above steps do not resolve the issue, connect the radio unit to a power supply outside the vehicle.
If the radio functions properly, the issue may lie with the vehicle’s wiring or battery. If it does not work, the radio unit may need replacement.

5. Reinstall Components

After repairs, carefully reinstall the radio unit into the dashboard.
Reconnect the negative battery terminal securely.
