Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, screwdriver set, and electrical tape.
Ensure the vehicle is parked with the engine off. Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Check Battery Voltage

Use a multimeter to measure the battery voltage. It should read around 12.6 volts when fully charged.
If the voltage is low, charge the battery or replace it if it’s defective.

3. Inspect and Replace Fuses

Locate the fuse box and identify the fuse for the audio system.
Remove the fuse and check for continuity with a multimeter.
Replace any blown fuses with the appropriate rated fuse (check the owner’s manual for specifications).

4. Examine Wiring Connections

Remove the radio unit from the dashboard by unscrewing the mounting hardware.
Carefully inspect the wiring harness connections for any loose, frayed, or damaged wires.
Secure any loose connections and repair or replace damaged wires as necessary.

5. Check Ground Connections

Locate the ground wire for the radio, usually attached to the vehicle chassis.
Ensure the connection is clean and tight; sand the contact surface if there’s corrosion.

6. Test the Radio Unit

Reconnect the battery terminal and power on the vehicle.
If issues persist, consider testing the radio by connecting it to a different power supply, such as a bench power supply, to confirm if the radio itself is faulty.
