Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set.
Ensure the vehicle is parked on a level surface and the ignition is turned off. Disconnect the negative battery terminal for safety.

2. Software Update

Check the official Ford website for the latest infotainment system software updates.
If an update is available, download it onto a USB drive formatted to FAT32.
Insert the USB drive into the USB port of the vehicle and follow the on-screen prompts to update the system.

3. Reset the Infotainment System

After reconnecting the negative battery terminal, start the vehicle.
Press and hold the "Power" and "Volume" buttons on the infotainment unit simultaneously for about 10 seconds until the system reboots.

4. Inspect Wiring and Connections

Remove the trim panel surrounding the infotainment unit using a trim removal tool.
Unscrew and gently pull out the infotainment unit.
Inspect the wiring harness for any signs of wear, corrosion, or loose connections. Secure any loose connectors and replace damaged wiring if necessary.

5. Check Battery and Electrical System

Use a multimeter to check the vehicle's battery voltage; it should read between 12.4V and 12.7V when the vehicle is off.
If the voltage is low, consider charging or replacing the battery. Check the alternator output while the engine is running to ensure it's functioning correctly.
