Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wire connectors.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Test Radio Fuse

Locate the fuse box, usually found under the dashboard or near the battery.
Remove the radio fuse using a fuse puller or pliers.
Use a multimeter to check for continuity in the fuse. If it’s blown, replace it with a fuse of the same amperage.

3. Check Wiring Connections

Remove the radio unit from the dashboard (typically involves unscrewing mounting screws and gently pulling it out).
Inspect the wiring harness for loose connections, frayed wires, or corrosion.
If any issues are found, repair or replace the damaged wiring.

4. Test Battery Voltage and Ground

Reconnect the battery and turn on the radio.
Use a multimeter to check the battery voltage at the radio harness while the radio is operating. It should be around 12V.
Check the ground connection by measuring voltage between the ground wire and a known good ground; it should read close to 0V.

5. Evaluate the Ignition Switch

If the radio loses power when the key is in the accessory position, the ignition switch may be faulty.
Test the ignition switch for proper operation using a multimeter or replace it if necessary.
