BMS sensors (i.e., Blind Spot Monitoring System sensors) are typically installed on both sides of the vehicle's rear bumper or inside the taillights, with specific locations varying by vehicle model design. The system uses radar technology to monitor the blind spots within a range of approximately 20 meters behind the vehicle. When other vehicles or obstacles are detected, it alerts the driver via a warning light on the rearview mirror. For example, the module model for vehicles such as the Mazda CX-30 is BDTS-67Y30-CKF621. Sensors of some brands like Crown require connection to the CAN bus for communication and proper power supply to avoid malfunctions. During installation, ensure the sensor area remains clean to prevent snow or dirt from affecting performance, and use twisted-pair wiring to enhance anti-interference capability. The system activates automatically when the vehicle speed exceeds 10 km/h, but may have monitoring limitations for rapidly approaching vehicles or stationary objects, so drivers must remain vigilant.
