BLIND SPOT MONITORING (BSM) SYSTEM
id921100000000
Purpose of Adoption
• A blind spot monitoring (BSM) system has been adopted for assisting the driver in confirming the area behind the vehicle when changing lanes.
• This system detects a vehicle approaching from the rear of the vehicle in an adjacent lane while the vehicle is traveling, or an approaching vehicle, motorcycle, or pedestrian when backing up the vehicle from a garage or parking lot while the vehicle is stopped to warn the driver.
• The vehicle rear detection uses the 24 GHz quasi-millimeter radar sensors equipped to the right and left rear end panels. A vehicle, motorcycle, or pedestrian is detected by this quasi-millimeter radar.
Service Point
• Blind spot monitoring (BSM) radar aiming
-
― The blind spot monitoring control module is required to correctly determine the position of an object at the rear, and the radar aiming operation using the SST is required to adjust a deviation in the radar emission angle when replacing the control module.
― The aiming procedure is the same as the RVM radar aiming equipped to the CX-5. Always verify the workshop manual before performing the procedure.
• Blind spot monitoring (BSM) configuration
-
― If the control module is replaced with a new one, the configuration operation using the M-MDS is not required because vehicle specification information is read automatically (auto configuration) via CAN communication from the instrument cluster when the ignition is switched ON.
Common Inquiry
• Not applicable
Other
• The blind spot monitoring (BSM) system has the following two functions.
Blind spot monitoring (BSM) function
-
• The detection of an approaching vehicle starts at a vehicle speed of 15 km/h {9.3 mph} or more, and if any of the following vehicles is detected, the function alerts the driver of the approaching vehicle by turning the BSM warning indicator light (outer mirror) on the vehicle approaching side on.
-
― The detected approaching vehicle enters the alert area.
― An approaching vehicle is detected which will reach the alert area front end within 5.5 s.
-
• In addition, when the BSM warning indicator light is turned on and the turn light switch is turned on to the side in which the BSM warning indicator light is turned on, the BSM warning indicator light is flashed and a warning sound is activated to alert the driver.
Rear cross traffic alert (RCTA) function
-
• An approaching vehicle or a pedestrian when backing up the vehicle from a garage or parking lot is detected to warn the driver.
• When the selector lever is in the R position (ATX)/shift lever is in the R position (MTX), the detection of an approaching vehicle or a pedestrian starts. When an approaching vehicle or a pedestrian entering the alert area within 3 s is detected, the BSM warning indicator lights on both sides are flashed and a warning sound is activated to alert the driver.
