Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Fuses

Locate the fuse box (refer to the owner's manual for location).
Remove the cover and inspect the audio-related fuses for continuity.
- Tools Required: Fuse puller or pliers.
Replace any blown fuses with the correct amperage.

3. Inspect Audio Settings

Reconnect the battery terminal.
Start the vehicle and turn on the radio.
Check if the mute function is engaged; if so, disable it.
Adjust the volume to ensure it is not set to the lowest level.

4. Test Audio Sources

Cycle through the audio sources (AM, FM, Bluetooth, USB).
Ensure Bluetooth devices are properly paired and connected.
Confirm that the source selected is functioning correctly.

5. Check Connections

If the issue persists, remove the radio head unit to inspect connections.
- Tools Required: Screwdriver set.
Ensure all wiring harnesses are securely connected.
Look for any visible damage or corrosion on connectors.

6. Inspect Battery Voltage

If no issues are found in previous steps, check the vehicle's battery voltage.
- Tools Required: Multimeter.
A healthy battery should read approximately 12.6 volts or more.
If voltage is low, consider charging or replacing the battery.
