how to fix the black screen issue in BMW X5 F15 (2014-2019)

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
• Ensure the vehicle is parked on a flat surface and the engine is off before starting repairs.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Check Battery Voltage

• Use a multimeter to measure the battery voltage.
• If voltage is below 12.4V, charge or replace the battery.

3. Inspect Fuses

• Locate the fuse box (usually found under the dashboard or in the engine compartment).
• Check the fuse diagram in the owner's manual to identify fuses related to the infotainment system.
• Replace any blown fuses with the same amperage rating.

4. Reconnect or Inspect Wiring

• Remove the infotainment unit by unscrewing the securing bolts (use a socket set).
• Gently pull the unit out and inspect the wiring harness for any loose connections or damage.
• Firmly reconnect any loose connectors and ensure all wiring is in good condition.
• Reinstall the infotainment unit and secure with bolts.

5. Perform Hard Reset

• Reconnect the negative terminal of the battery.
• Start the vehicle and allow it to idle for a few minutes.
• Check if the screen has turned back on.

6. Software Update (if applicable)

• If the problem persists, connect the OBD-II scanner to check for software updates.
• Follow the manufacturer’s instructions to update the infotainment system software if necessary.
