Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and fuse puller.
Disconnect the vehicle's battery to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box in the engine compartment and the cabin.
Use the fuse puller to check the fuses related to the radio (refer to the owner's manual for specific fuse numbers).
If any fuses are blown, replace them with the same amperage rating.

3. Inspect Wiring Connections

Remove the radio from the dashboard using a screwdriver.
Carefully unplug the wiring harness from the back of the radio.
Inspect the pins and connectors for corrosion or damage.
Repair or replace any damaged wires and ensure all connections are secure.

4. Test the Radio Unit

Reconnect the wiring harness to the radio.
Reconnect the battery and turn on the ignition.
Use a multimeter to check for voltage at the radio's power connector (should be around 12V).
If power is present and the radio still does not work, the radio unit may need replacement.

5. Replace Radio Unit (if necessary)

If the radio unit is confirmed faulty, remove it completely by unscrewing it from the dashboard.
Install the new radio unit by reversing the removal process and ensuring all connectors are secure.
Test the new unit to ensure functionality.
