Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, socket set.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Fuse

Locate the fuse box (consult the owner's manual for the exact location).
Remove the cover of the fuse box.
Identify the fuse for the infotainment system (refer to the fuse diagram).
Use a fuse puller to remove the fuse and inspect it for continuity.
- If blown, replace it with a new fuse of the same amperage.
- If intact, reinstall the fuse and proceed to the next step.

3. Check Wiring Connections

Reconnect the negative battery terminal.
Remove the infotainment system from the dashboard (usually involves removing screws and panel clips).
Inspect the wiring harness for any loose connections or damage.
Ensure that the power and ground wires are secure and free from corrosion.

4. Test Infotainment System Power

With the infotainment unit still disassembled, use a multimeter to test the power and ground connections.
Confirm that there is voltage at the power wire when the ignition is in the 'ON' position.
- If no voltage is present, trace the wiring back to the source to find the issue.

5. Reassemble and Test

If the wiring is intact and the fuse is good, reassemble the infotainment unit.
Reconnect the negative battery terminal.
Start the vehicle and check if the infotainment system powers on.
