Solution

1. Preparation

Gather tools:
- Screwdriver set
- Multimeter
- OBD-II scanner
- Pliers
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the radio (refer to the owner's manual).
Remove the fuse using pliers and inspect it. If it appears blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the radio.

3. Check Wiring Connections

Remove the radio from the dashboard using the appropriate tools.
Inspect the wiring harness for any loose wires, frayed connections, or corrosion.
Reconnect any loose wires securely and clean any corrosion with contact cleaner.
Reinstall the radio and test its operation.

4. Test Power Supply

With the radio still removed, use a multimeter to check for power at the radio connector.
Set the multimeter to measure DC voltage.
Probe the power and ground wires to confirm there is a voltage reading (typically 12V).
If no voltage is detected, trace the wiring back to the fuse box and check for any breaks or shorts.

5. Reset the Radio

If the radio is still unresponsive, attempt to reset it. This may involve disconnecting the power for several minutes and then reconnecting it.
Reinstall the radio and check its functionality again.
