Solution

1. Preparation

Gather all tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box in the vehicle (refer to the owner's manual for exact location).
Identify the fuse related to the audio system; it is usually labeled in the fuse box cover.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown: Replace it with a new fuse of the same amperage.
- If not blown: Reinsert the fuse and proceed to the next step.

3. Inspect Wiring and Connectors

Remove the radio unit from the dashboard following the manufacturer's instructions.
Inspect the wiring harness connected to the back of the radio:
- Ensure all connections are secure and free of corrosion.
- Look for any signs of frayed wires or damage; repair or replace as necessary.

4. Test Power Supply

Reconnect the negative battery terminal.
Use a multimeter to test the voltage at the radio connector:
- Turn the ignition to the "on" position.
- Check for 12 volts at the power supply pin. If no voltage is present, trace back to the fuse box.

5. Reassemble and Test

After completing repairs, reassemble the radio unit into the dashboard.
Reconnect the negative battery terminal, start the vehicle, and test the radio.
