Solution

1. Preparation

Gather necessary tools, including a socket set, multimeter, and OBD-II scanner.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box: Refer to the owner's manual to find the location of the fuse box.
Remove the fuse: Use a fuse puller or needle-nose pliers to carefully extract the radio fuse.
Inspect the fuse: Check if the fuse is blown (a broken wire or discoloration indicates failure).
Replace the fuse: If blown, replace it with a new fuse of the same amperage (typically 10-15A for radio). Reinsert it into the fuse box.

3. Inspect Wiring Connections

Remove radio unit: Using a socket set, carefully unscrew and pull out the radio from the dashboard.
Check wiring harness: Inspect the connectors for any signs of corrosion, looseness, or damage.
Reconnect: If the connections are loose, firmly reconnect them. If damaged, replace the wiring harness.

4. Test Radio Power Supply

Reposition multimeter: Set the multimeter to DC voltage and connect the positive probe to the radio power supply wire.
Turn the ignition to ON: Check if there is voltage present (should read around 12 volts).
No voltage: If no voltage is detected, trace back to the wiring and check for breaks or faults.

5. Reinstall Radio and Reconnect Battery

Reinstall the radio unit: Secure it back into the dashboard and reattach any screws.
Reconnect the negative battery terminal: Ensure it is tightened properly to prevent any power issues.
