The Blind Spot Monitoring (BSM) system uses two radar-based sensors, located inside the rear bumper fascia, to detect highway licensable vehicles (automobiles, trucks, motorcycles, etc.) that enter the blind spot zones from the rear/front/side of the vehicle.

Where are blind spot sensors located?

The blind spot detection system uses the radar sensors in the rear of the vehicle. These sensors are normally behind the rear bumper on each side. However, there are some instances where the sensor is in a different location, such as in the tail light or in the quarter panel behind the bumper cover.

What is the BSM system?

BSM stands for blind spot monitor, the generic term for systems that monitor areas adjacent to and just behind a vehicle, the blind spots where other vehicles are out of the view of the driver and outside mirrors.
