Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, fuse puller, and basic hand tools (screwdrivers, socket set).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller to remove the radio fuse.
Inspect the fuse visually and replace it if blown (typically a 10A or 15A fuse for the radio).
Reinsert the fuse and reconnect the battery.

3. Check Wiring Connections

Remove the radio unit using appropriate tools to access the wiring harness.
Inspect all wiring connections for signs of damage, corrosion, or looseness.
Clean any corroded connectors with electrical contact cleaner and ensure they are securely connected.

4. Test the Radio

Reconnect the battery and turn on the ignition.
Power on the radio to check if it operates correctly.
If the radio still fails, consider swapping it with a known good unit to confirm if the radio itself is faulty.
