Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a safe area with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and identify the audio system fuse(s) using the diagram on the cover.
Use a fuse puller or pliers to check the fuses; replace any blown fuses with the same amperage rating.

3. Check Wiring Connections

Remove the trim panel surrounding the audio system.
Unscrew and pull out the radio unit from the dashboard.
Inspect all wiring harness connections for secure attachment and any signs of damage or corrosion.
Reconnect any loose connectors and repair any damaged wiring using electrical tape or connectors.

4. Test Speaker Outputs

With the radio powered on, set the multimeter to the resistance setting (ohms).
Connect the multimeter probes to the speaker wires (positive and negative) to check for continuity.
A reading of around 4-8 ohms indicates a functioning speaker; replace any speakers showing an open circuit.

5. Reset or Update Infotainment System

Refer to the vehicle's owner manual for the specific reset procedure for the audio system.
If available, connect the vehicle to Wi-Fi and check for software updates through the infotainment settings menu.
