Genuine Ford Blind Spot Monitors

What Is the Ford Blind Spot Information System?

The Ford Blind Spot Information System (BLIS), also known as a blind spot monitor, is a driver assistance system designed to help detect vehicles or other road users in areas that can be difficult to see using the vehicle's mirrors alone. BLIS is designed to provide additional awareness and should be used together with normal mirror and shoulder checks.

Depending on the Ford model and equipment level, blind spot sensors are typically positioned around the rear of the vehicle and monitor adjacent areas. When the system detects a vehicle in a blind spot, a warning indicator may illuminate in the corresponding side mirror or another designated location, helping alert the driver before changing lanes.

Common Ford Blind Spot Monitor Parts

The blind spot monitoring system consists of several components that work together to detect objects and communicate warnings to the driver.

• Blind Spot Sensor: Detects vehicles or objects within the monitored area beside and behind the vehicle.
• Sensor Bracket: Securely positions the blind spot sensor in the correct location and orientation.
• Wiring & Connectors: Provide electrical power and allow the sensor to communicate with the vehicle's electronic systems.
• Blind Spot Control Module: Processes information from the sensors and controls the system's warnings where applicable.

Because sensor position and calibration are important to the operation of BLIS, replacing a component with the correct vehicle-specific part is essential.

Why Isn't My Ford Blind Spot Detection Working?

If your Ford's blind spot detection system isn't operating correctly, there can be several possible causes. Common issues include:

• Dirty or obstructed sensors: Mud, dirt, snow or other debris can interfere with sensor operation.
• Damaged sensor or bracket: A collision or impact around the rear bumper or sensor mounting area can affect the sensor's position or condition.
• System or sensor fault: The vehicle may detect an internal fault and temporarily disable the system.
• Calibration requirements: Some repairs or sensor replacements may require specific calibration procedures.

If the BLIS warning light remains illuminated, a message appears on the dashboard, or the system consistently fails to operate, professional diagnosis may be required.

How To Reset Ford Blind Spot Sensors?

The reset procedure can vary depending on the Ford model, year and BLIS system fitted to the vehicle. In some cases, temporarily switching the vehicle off and restarting it may clear a temporary system issue. Cleaning the sensor area and ensuring there are no obvious obstructions is also a useful first step.

However, replacing or resetting a blind spot sensor is not always as simple as disconnecting and reconnecting the component. Some Ford vehicles may require diagnostic equipment, fault-code clearing or sensor calibration after a repair or replacement.

If your blind spot system continues to display a warning or doesn't operate after restarting the vehicle, we recommend having the system properly diagnosed rather than repeatedly resetting it. Always follow the procedures specified for your particular Ford model.
