Inspection

BSD Unit Alignment

To correctly detect vehicles in adjacent lanes with the radar, the sensor direction and the vehicle direction must be aligned. This is the BSD module alignment. If this alignment is not performed, as shown in the figure below, detection performance may deteriorate and false warnings may occur. In particular, this alignment procedure must be performed on vehicles with rear bumper collision repair, and on vehicles where the BSD unit has been replaced.

1. 1
   Vehicles with rear bumper collision damage and vehicles where the BSD units have been replaced must perform BSD unit alignment using GDS.
2. 2
   Select the "BSD Radar Calibration" procedure in the BSD system.

   

3. 3
   Perform the "BSD Radar Calibration" procedure according to the message on the GDS screen.
