Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required:
- Multimeter
- OBD-II scanner
- Fuse puller or pliers
- Screwdrivers
- Wire stripper/crimper
Ensure the vehicle is parked on a level surface, and the ignition is turned off.

2. Battery and Fuse Check

Open the hood and inspect the battery condition; ensure terminals are clean and tight.
Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify and pull the fuse for the radio using a fuse puller.
Inspect the fuse visually; replace it with a new fuse of the same amperage if blown (check the owner’s manual for fuse ratings).

3. Wiring Inspection

Remove the radio from the dashboard using the appropriate screwdriver.
Disconnect the wiring harness from the back of the radio.
Visually inspect the wiring for any signs of damage (fraying, corrosion).
Use the multimeter to measure continuity in the power wire and ground wire.
If damaged, repair the wiring using wire strippers and crimp connectors, ensuring a secure connection.

4. Reconnect and Test

Reconnect the wiring harness to the back of the radio.
Reinstall the radio into the dashboard.
Turn on the vehicle and test the radio for functionality.
