Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, small flat-head screwdriver, and replacement fuses if needed.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the Fuse Box: Open the driver’s side door and remove the cover to the fuse box.
Identify Audio Fuse: Consult the fuse diagram on the cover or in the owner's manual to find the audio system fuse.
Inspect the Fuse: Remove the audio system fuse using a fuse puller or pliers. Check if the filament is intact or blown.
Replace if Necessary: If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect Wiring and Connections

Remove the Radio: Use a small flat-head screwdriver to carefully pry off the surrounding trim panel. Unscrew and remove the radio unit from the dashboard.
Check Wiring Harness: Inspect the wiring harness connections for any looseness or damage. Ensure all connectors are seated properly.
Repair any Damage: If any wires are frayed or disconnected, repair or replace them as necessary.

4. Test Power Supply

Reconnect Battery: Temporarily reconnect the negative battery terminal.
Test Voltage: Use a multimeter to check for voltage at the radio's power connector. You should see around 12 volts. If no voltage is present, trace the power line back to the fuse box and check for continuity.

5. Reinstall Radio

Reassemble Components: If all checks are satisfactory, reinstall the radio unit and secure it with screws.
Reattach Trim Panel: Press the trim panel back into place ensuring it snaps securely.
