Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, socket set, fuse puller
Disconnect the negative battery terminal to ensure safety while working with electrical components.

2. Inspect Battery and Connections

Check the battery voltage using the multimeter; ensure it's above 12.4 volts.
Clean the battery terminals and ensure they are tightly connected.
Inspect cables for corrosion or wear and replace if necessary.

3. Check and Replace Fuse

Locate the fuse box (consult the owner's manual if needed).
Identify the radio fuse and use a fuse puller to remove it.
Inspect the fuse for any signs of damage; replace with the same amperage fuse if necessary.

4. Examine Wiring and Connectors

Remove the radio from the dashboard carefully.
Inspect the wiring harness for frayed wires or loose connections.
Secure any loose connections and repair or replace damaged wires as required.

5. Test Radio Unit

Using the multimeter, check the power and ground wires to the radio.
Ensure voltage is present (approximately 12 volts) while the ignition is in the "On" position.
If no power is detected, trace the wiring back to the ignition switch to ensure continuity.

6. Verify Ignition Switch Function

If all previous steps are fine, check the ignition switch.
Ensure it is functioning correctly and is not intermittently cutting power; replacement may be necessary if faulty.
