Where is the blind spot sensor on a Ford Bronco Sport?
The blind-spot sensor on the Ford Bronco Sport is a radar-based unit embedded in the rear bumper on the left and right sides, feeding the BLIS indicators in the side mirrors. In practice, there are no sensors in the doors or mirrors themselves—the sensors live behind the rear bumper near the outer edges.
Understanding Ford’s Blind Spot Information System (BLIS) on the Bronco Sport
The Bronco Sport’s BLIS watches adjacent lanes for vehicles that enter your blind spots as you change lanes. When a vehicle is detected, the corresponding side mirror’s indicator illuminates, and some trims may emit an audible alert. The system relies on radar sensors located in the rear bumper and data processed by the vehicle’s safety electronics to warn you of nearby traffic.
Where exactly are the sensors located?
Before listing the specifics, note that the sensors are installed in the rear bumper corners, one on the left and one on the right, hidden behind the bumper cover near the outer edges.
- Left rear bumper sensor (BLIS)
- Right rear bumper sensor (BLIS)
With the sensors in place, the BLIS system communicates with the vehicle’s mirrors and instrument cluster to alert you about vehicles in your blind spots during lane changes and when backing out of tight spaces.
How the system works and what to know
Detection method
The Bronco Sport uses radar-based sensors to detect moving vehicles in adjacent lanes. Data from the sensors is processed by the vehicle’s electronic control units to determine when to alert the driver.
Common limitations
Radar-based blind-spot sensing can be affected by weather, dirt on the bumper, or unusual traffic patterns. It may not warn in every scenario, and drivers should still perform a visual check before changing lanes.
What to do if you can't locate the feature or suspect a fault
If you suspect the BLIS sensors are obstructed or malfunctioning, ensure the bumper and sensors are clean, verify BLIS is enabled in the vehicle settings, and consult a Ford dealer for a diagnostic check. Some issues may require software updates or sensor recalibration after repairs.
Summary
In the Ford Bronco Sport, the blind-spot sensor is a pair of radar units embedded in the rear bumper corners (left and right). They feed the BLIS indicators in the side mirrors to warn you of vehicles in adjacent lanes. For safe driving, rely on both the system and your own observations, especially in adverse weather or challenging traffic conditions.
