Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, wire brush, electrical tape
Disconnect the negative terminal of the battery to avoid any electrical shorts while working on the radio.

2. Check Battery and Connections

Inspect the battery terminals for corrosion and ensure they are tight.
Use a multimeter to measure the battery voltage; it should be between 12.4V to 12.6V when the vehicle is off.
Tighten any loose connections and clean terminals with a wire brush if necessary.

3. Inspect and Replace Radio Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the radio fuse (consult the owner’s manual for the exact location).
Remove the fuse and inspect it for any signs of damage. If blown, replace it with a fuse of the same amperage.

4. Check Wiring Connections

Remove the radio unit from the dashboard by unscrewing any screws holding it in place.
Inspect the wiring harness for loose or damaged connections.
Reconnect any loose wires and secure the harness properly.

5. Test the Radio

Reconnect the battery terminal and turn on the ignition without starting the engine.
Power on the radio to check if it operates consistently without turning off.
If the issue persists, consider replacing the radio or seeking professional assistance.
