How to Fix BCI Malfunction in Infiniti QX80

If you own an Infiniti QX80 and are experiencing issues with the BCI (Backup Collision Intervention) system, there are steps you can take to diagnose and fix the problem. The BCI system is designed to help prevent accidents while reversing by monitoring the area behind the vehicle and alerting the driver to the presence of objects or pedestrians. However, if the BCI system malfunctions, it can be frustrating and potentially dangerous. Read on to learn how to fix BCI malfunction in your Infiniti QX80.

1. Check for Error Codes

The first step in fixing BCI malfunction is to check for any error codes that may be stored in the vehicle’s computer system. To do this, you will need an OBD-II scanner. Simply plug the scanner into the OBD-II port, which is usually located under the dashboard on the driver’s side. Follow the instructions provided with your scanner to read the error codes. These codes can provide valuable information about the specific problem with the BCI system.

2. Inspect Sensors and Wiring

If the error codes indicate a problem with the BCI system, the next step is to inspect the sensors and wiring. Start by visually inspecting the sensors located in the rear of the vehicle. Look for any signs of damage or obstruction, such as dirt or debris covering the sensors. Cleaning the sensors with a soft, lint-free cloth may help improve their functionality.

Next, check the wiring connected to the BCI system. Look for any loose or damaged wires that may be causing a poor connection. If you find any issues, repair or replace the wiring as necessary.

3. Reset the BCI System

If the error codes persist after inspecting the sensors and wiring, a simple reset of the BCI system may resolve the issue. To reset the BCI system, follow these steps:

  1. Turn off the vehicle and remove the key from the ignition.
  2. Disconnect the negative terminal of the vehicle’s battery.
  3. Wait for at least 10 minutes to allow the BCI system to fully power down.
  4. Reconnect the negative terminal of the battery.
  5. Start the vehicle and check if the BCI system is functioning properly.

Note: Resetting the BCI system may also reset other vehicle settings. Make sure to reset any preferences, such as radio presets or seat positions, after performing the reset.

4. Seek Professional Help

If none of the above steps resolve the BCI malfunction, it is recommended to seek professional help. An authorized Infiniti service center or a qualified automotive technician will have the expertise and tools to diagnose and fix complex BCI system issues. They can also provide software updates if necessary to ensure the BCI system is up-to-date.

Keep in mind that the BCI system in the Infiniti QX80 is a sophisticated safety feature that requires specialized knowledge to repair. Attempting to fix it yourself without proper expertise can potentially cause further damage or lead to inaccurate functionality.
