Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked with the ignition turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the fuse related to the radio (refer to the fuse diagram).
Use a fuse puller or pliers to remove the fuse and check if it is blown (the filament inside should be intact).
Replace with a new fuse of the same amperage if blown.

3. Inspect Wiring Connections

Remove the radio unit from the dashboard by unscrewing the screws and gently pulling it out.
Check the wiring harness connections to ensure they are firmly connected and not damaged.
If any wires are frayed or disconnected, repair or replace as necessary.

4. Test Radio Power Supply

Using a multimeter, check the voltage at the radio power connector.
If power is present (typically 12V), the radio may need replacement.
If no power is detected, trace the wiring back to the fuse box and check for continuity.

5. Reassemble and Reconnect

Once all checks and repairs are complete, reconnect the radio unit.
Reattach any screws and panels removed during the process.
Reconnect the negative terminal of the battery.
