Solution

1. Preparation

Gather tools: multimeter, fuse puller, socket set, and a screwdriver.
Disconnect the vehicle battery by removing the negative terminal to ensure safety while working on electrical components.

2. Inspect Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller to remove the audio system fuse.
Visually inspect the fuse and replace it if it is blown with one of the same amperage.

3. Check Wiring Connections

Remove the radio unit from the dashboard using a screwdriver to access the wiring.
Inspect all wiring connectors for any signs of corrosion, damage, or loose connections.
Ensure all connectors are securely fastened and replace any damaged wiring as necessary.

4. Test Power Supply

With the multimeter set to the DC voltage setting, probe the power input wires at the back of the radio.
Confirm the radio is receiving the correct voltage (usually around 12V).
If no voltage is present, trace the wiring back to the fuse box and check for continuity.

5. Reassemble and Test

Reconnect all wiring and securely mount the radio back into the dashboard.
Reconnect the battery terminal, ensuring it is tight and secure.
Turn on the vehicle and test the radio functionality.
