Solution

1. Preparation

Gather tools: Multimeter, socket set, wire brush (for cleaning), and a replacement fuse if needed.
Ensure the vehicle is turned off and keys are removed from the ignition.

2. Check Battery Voltage

Connect the multimeter leads to the battery terminals (red to positive, black to negative).
Confirm that the battery voltage reads between 12.4 - 12.6 volts for a fully charged battery.
If the voltage is low, charge or replace the battery as necessary.

3. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the socket set to remove the cover and locate the radio fuse (refer to the fuse diagram).
Remove the fuse and inspect it for continuity. If it appears blown (the wire inside is broken), replace it with a new fuse of the same amperage.
Reinstall the fuse and check if the radio powers on.

4. Verify Wiring Connections

Remove the radio from the dashboard using a socket set.
Inspect the wiring harness at the back of the radio for any loose connections or damage.
Clean any corrosion on the connectors with a wire brush and reconnect securely.

5. Check Ground Connection

Locate the ground wire for the radio, typically found near the mounting bracket.
Ensure the ground connection is tight and free of rust or dirt.
If rust is present, clean the area and reattach securely.
