Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, trim removal tools.
Disconnect the negative battery cable to prevent electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box: Refer to the owner's manual for the location of the fuse box.
Remove the fuse: Use fuse puller or pliers to carefully remove the audio system fuse.
Inspect the fuse: Check if the wire inside the fuse is broken. If it is, replace it with a new fuse of the same amperage (typically 10A or 15A).
Reinstall the fuse: Ensure it is seated properly in the fuse holder.

3. Inspect Wiring Connections

Remove the radio unit: Use trim removal tools to carefully detach the dashboard trim and access the radio.
Check connectors: Ensure all wiring harness connections are secure and undamaged.
Repair or replace: If any wires are frayed or connectors are loose, repair the wiring or replace connectors as necessary.

4. Test the Power Supply

Reconnect the battery: Temporarily reconnect the negative battery cable to test for power.
Check voltage: Using a multimeter, measure the voltage at the radio power connector. It should read approximately 12V.
If no voltage: Trace back to the fuse box and check connections or wiring for breaks.

5. Reassemble and Finalize

Reinstall the radio: Once all checks and repairs are complete, reinstall the radio and dashboard trim.
Reconnect the battery: Secure the negative battery cable.
Test the radio: Turn on the vehicle and check if the radio powers on.
