Solution

1. Preparation

Gather tools: fuse puller, multimeter, socket set, and a screwdriver.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box; refer to the owner’s manual for the exact location.
Remove the cover and identify the fuse for the audio system.
Use a fuse puller to carefully remove the fuse.
Inspect the fuse for a break in the filament.
If blown, replace it with a fuse of the same amperage rating (refer to the owner’s manual for specifications).
Reinstall the fuse cover.

3. Check Battery Voltage

Reconnect the negative battery terminal.
Use a multimeter to check the battery voltage; it should read between 12.4V to 12.7V when the vehicle is off.
If the voltage is low, charge the battery or replace it if necessary.

4. Inspect Wiring and Connectors

Remove the radio from the dashboard using the appropriate tools.
Visually inspect the wiring harness and connectors for any signs of wear, corrosion, or loose connections.
If any damage is found, repair or replace the affected wires or connectors.

5. Test the Radio

Reconnect the radio and any harnesses securely.
Reconnect the negative battery terminal.
Turn the ignition to the "ON" position and check if the radio powers on.
