Solution

1. Preparation

Gather all necessary tools: fuse puller, multimeter, screwdriver set, and wiring harness adapter (if needed).
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the audio system, usually indicated in the diagram on the fuse box cover.
Use a fuse puller to remove the fuse and visually inspect it.
- If blown: Replace with a fuse of the same amperage rating (usually 10A or 15A for the radio).

3. Inspect Wiring Connections

Remove the radio unit from the dashboard using the screwdriver set.
Check the wiring harness connections at the back of the radio.
- Ensure all connectors are firmly attached and free of damage.
- If using an adapter, verify that it is correctly installed.

4. Test Battery and Ground Connections

Reconnect the negative battery terminal.
Use a multimeter to measure the voltage at the radio's power input terminal; it should read 12V when the ignition is on.
Inspect the ground wire connection; if it is corroded or loose, clean and secure it.

5. Replace the Radio (if necessary)

If all previous checks are satisfactory and the radio still does not function, consider replacing the radio unit.
Follow the manufacturer’s instructions for installation and wiring.
