Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner.
Ensure the vehicle is parked with the ignition off.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller or pliers to remove the audio system fuse.
Inspect the fuse for continuity; replace if blown.
Reinsert the fuse and check if sound is restored.

3. Check Wiring Connections

Remove the panels or covers to access the audio system components (head unit, amplifier, and speakers).
Inspect all wiring harnesses for signs of damage, corrosion, or loose connections.
Reconnect any loose connectors and repair any damaged wires as needed.

4. Test Amplifier Operation

If the vehicle has an external amplifier, check the power and ground connections using a multimeter.
Ensure the amplifier is receiving proper voltage (typically around 12V).
If the amplifier is faulty, replace it with a compatible unit.

5. Reset Infotainment System

With the ignition on, press and hold the power button on the infotainment system for 10 seconds to reset.
Wait for the system to restart and test the audio output.
