Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is off and parked on a flat surface.

2. Inspect Battery Connections

Locate the battery under the hood.
Use a socket wrench to disconnect the negative terminal first, followed by the positive terminal.
Clean any corrosion using a wire brush and baking soda solution.
Reconnect the terminals, ensuring they are tight.

3. Check Fuses

Locate the fuse box, typically found under the dash or in the engine compartment.
Identify the fuse specific to the radio/audio system (refer to the fuse diagram).
Remove the fuse using a fuse puller and inspect it for damage; replace if necessary.

4. Examine Wiring Harness

Remove the radio unit from the dashboard using a socket set.
Inspect the wiring harness for any frayed wires or loose connections.
If damaged, repair or replace the wiring harness as needed.

5. Test Radio Power Supply

Reconnect the radio unit temporarily without securing it back into the dashboard.
Use a multimeter to measure voltage at the radio connector. It should read approximately 12V when the vehicle is on.
If voltage is absent, trace wiring back to the battery and check for breaks.

6. Verify Ground Connection

Locate the ground wire for the radio, often connected to the chassis.
Remove the connection, clean the contact point, and resecure it tightly.
Test for continuity between the ground connection and the chassis using a multimeter.
