Solution

1. Preparation

• Gather tools and parts needed for repair.
• Disconnect the vehicle battery to ensure safety during repairs.
• Tools required: Socket set, OBD-II scanner, Multimeter, Wiring harness connectors.

2. Inspect Battery Connections

• Locate the battery under the hood.
• Using a socket set, remove the negative terminal first followed by the positive terminal.
• Clean any corrosion using a wire brush and reconnect the terminals, ensuring they are tight.

3. Check Fuses

• Locate the fuse box, usually under the dashboard or near the driver's side.
• Remove the cover and locate the fuse for the radio/audio system.
• Use a fuse puller or pliers to remove the fuse and visually inspect it for continuity.
• Replace with a new fuse of the same amperage if blown.

4. Examine Radio Wiring Harness

• Remove the radio unit from the dashboard using appropriate tools.
• Inspect the wiring harness connected to the back of the radio for any loose connections or damage.
• Reconnect any loose wires and replace damaged connectors or wires as needed.

5. Test Radio Functionality

• Reinstall the radio unit securely in the dashboard.
• Reconnect the vehicle battery starting with the positive terminal followed by the negative.
• Turn on the ignition and test the radio for functionality.
