Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the Fuse Box: Reference the owner's manual for the location of the fuse box.
Check Fuses: Remove the fuse for the radio (usually labeled as "Audio" or "Radio") and inspect it for continuity. Replace if blown.
Reinstall the Fuse: Ensure it fits snugly and is properly seated in the fuse box.

3. Test Radio Voltage

Reinstall Battery Terminal: Reconnect the negative battery terminal.
Access Radio Connector: Remove the radio unit using trim removal tools.
Measure Voltage: With the multimeter set to DC voltage, check for power at the radio connector. You should see approximately 12V. If not, trace wiring back to the fuse box.

4. Inspect Wiring Connections

Check Connections: Look for any loose, damaged, or corroded wiring at the radio connector and along the harness.
Repair as Necessary: If any issues are found, repair or replace the wiring as needed.

5. Reassemble

Reinstall Radio: Carefully reattach the radio unit and ensure all connectors are securely fastened.
Final Check: Reconnect the negative battery terminal and test the radio for functionality before fully reassembling the dash.
