Solution

1. Preparation

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

2. Check and Replace the Fuse

Locate the vehicle's fuse box; refer to the owner's manual for the exact location.
Identify the fuse designated for the radio using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown (the metal strip inside is broken), replace it with a new fuse of the same amperage (typically 10-15A for radios).

3. Inspect Wiring Connections

Remove the radio from the dashboard by unscrewing any mounting screws and gently pulling it out.
Check the wiring harness connected to the back of the radio for any signs of damage.
Ensure all connectors are secure and free of corrosion; clean if necessary.

4. Test for Voltage

Set your multimeter to measure DC voltage.
Reconnect the wiring harness to the radio.
With the ignition switch on, probe the power connector of the radio to confirm voltage is present (should be around 12V).
If no voltage is detected, trace wiring back to the fuse box for breaks or disconnections.

5. Reinstall Radio or Replace

If the radio is tested and confirmed working, reinstall it by reversing the removal steps.
If the radio is non-functional, replace it with a new unit following the manufacturer's installation guidelines.
Reconnect the negative battery terminal and test the radio for functionality.
