Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wiring repair tools.
Disconnect the negative terminal of the battery to prevent any electrical short circuits.

2. Inspect and Replace Fuses

Locate the fuse box: It is usually found under the dashboard or in the engine compartment.
Remove the cover and check the fuse diagram for the radio-related fuses.
Replace any blown fuses with the same amperage rating (typically 10-15A).
Reinstall the fuse box cover and reconnect the battery terminal.

3. Check Wiring Connections

Remove the radio from the dashboard carefully using appropriate trim removal tools.
Inspect the wiring harness connectors for any signs of corrosion or damage.
Ensure all connectors are securely fastened and seated properly.
Repair any damaged wiring using solder and heat shrink tubing or replace the harness if necessary.

4. Voltage Testing

With the multimeter, test the power wire on the radio harness while the ignition is on.
Confirm that the voltage reading is between 12-14 volts.
If no voltage is present, trace back to the fuse box or ignition switch for further inspection.

5. Test the Radio

If the radio still does not power on after checking all connections and fuses, test the unit by connecting it to a 12V power source outside the vehicle.
If the radio powers up, it may need to be replaced.
