Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and any replacement fuses if needed.
Ensure the vehicle is parked in a safe area with the engine off and the key removed.

2. Battery and Fuse Inspection

Check Battery Voltage:
- Connect the multimeter to the battery terminals.
- Ensure voltage is between 12.4 - 12.7 volts for a healthy battery.
Inspect Fuse:
- Locate the fuse box (refer to the owner's manual for exact location).
- Identify the fuse for the infotainment system (usually labeled) and remove it.
- Inspect the fuse visually; if the metal strip is broken or burnt, replace it with a new fuse of the same amperage.

3. Wiring and Connector Check

Inspect Wiring Harness:
- Remove the infotainment unit from the dashboard (refer to service manual for disassembly instructions).
- Check all connectors for tightness and signs of corrosion or damage.
- Reconnect any loose connectors and repair damaged wires as necessary.

4. System Reset

Disconnect Battery:
- Using a socket set, disconnect the negative terminal of the battery first, followed by the positive terminal.
- Wait for at least 5 minutes to allow all systems to reset.
- Reconnect the battery terminals, starting with the positive terminal, then the negative.
