How to Fix Ford Blind Spot System Fault: Causes and Solutions

Many contemporary cars come equipped with a blind spot monitoring feature, often referred to as Blind Spot Detection or Blind Spot Information Systems (BSIS). This technology assists drivers in identifying and preparing for areas that are difficult to see. These challenging-to-observe zones, known as blind spots, can pose risks and potentially lead to vehicle damage.

A malfunctioning blind spot warning (BSW) system increases road risks significantly. When a warning message appears, what does it indicate, and how can you address it? This article explores these questions in detail.

Understanding the Blind Spot System Fault Message

A blind spot system fault message appears on your dashboard when the system detects an issue that prevents it from identifying blind spots ahead. This alert signals that the system is no longer functioning correctly, which can be hazardous since it normally helps spot dangerous areas on the road in a timely manner.

Causes of Blind Spot System Fault Messages and Solutions

Several factors can trigger the blind spot system fault message. You can try resetting the system or applying specific fixes to resolve the issue.

Extreme Weather Conditions

Harsh weather is a frequent cause of the blind spot system fault message appearing on your car’s dashboard. Conditions like fog, snow, ice, or heavy rain can impair the blind spot radar sensor’s functionality. Precipitation, such as rain or snow, may obstruct the BSW sensor, affecting its performance.

Such conditions may prevent the BSW system from detecting vehicles in blind spots from any direction. To fix this, wait for the weather to improve before driving, ensuring the sensor can function properly.

Faulty Sensor or Camera

Ford’s blind spot warning system (BSWS) typically relies on radar sensors, though some vehicles use cameras. These components enable the system to efficiently detect hard-to-see areas. If a sensor is damaged, it may fail to function, triggering the fault message on your dashboard.

If the sensor is damaged, replacing it is the best solution. Fortunately, replacing a blind spot sensor is relatively affordable. Ensure you follow the proper replacement procedure.

Obstructed Sensor

The blind spot system is designed to monitor up to 120 inches (approximately 10 feet) past the rear bumper and across lane widths on both sides of the vehicle. However, obstructions can reduce the system’s detection range. For example, driving on steep inclines or hills may cause debris to clog the sensor, located beneath the rear bumper, preventing it from detecting blind spots. If water, dirt, snow, or debris accumulates on the sensor, clean it thoroughly to restore functionality.

Improper Sensor Placement

Incorrect sensor positioning can also trigger the blind spot system fault message. If the sensor is misaligned, it may fail to send signals to the system. Unless specified otherwise in the owner’s manual, Ford’s blind spot sensors are typically located beneath the rear bumper.

If the sensor is not correctly positioned, remove and reinstall it according to the manufacturer’s guidelines. This should restore proper signal transmission to the system.

Steps to Reset the Ford Blind Spot Fault Message

Resetting the blind spot system fault message is a simple process. Follow these steps:

• Park the vehicle and turn off the engine.
• Identify the location of the blind spot system components.
• Locate the blind spot detection sensor: In most recent Ford models, sensors are found in the side view mirrors, beneath the rear bumper, or on the left and right sides of the rear bumper.
• Check the sensor for obstructions: Remove any dirt, grime, moisture, snow, or ice that may be clogging the sensor, as these are common culprits.
• Turn off the vehicle’s engine.
• Wait a few minutes.
• Start the vehicle.
• Allow the system to recalibrate.

After completing these steps, the blind spot system should reset, and the fault message should no longer appear.

Frequently Asked Questions

Where are blind spot sensors located?

Blind spot sensors are strategically placed to maximize their detection capabilities. In most Ford vehicles, they are located in the side view mirrors, beneath the rear bumper, or on the left and right sides of the rear bumper. These positions optimize the sensors’ ability to monitor areas beside and behind the vehicle.

What is the cost to repair blind spot monitoring?

Fixing a blind spot monitoring system is generally affordable, typically costing between $250 and $500, including labor. However, if you also need to repair related systems like lane change assist or lane departure warning systems, costs could rise to around $1,500. Addressing issues one at a time may help manage expenses.

Conclusion

The blind spot system in your Ford enhances both safety and driving convenience. When a blind spot fault message appears, take immediate action to address it. I recommend promptly resolving any vehicle issues to prevent damage to other critical components. Regularly check and maintain your blind spot sensors to ensure they remain in optimal condition.
