BLIND SPOT DETECTION (BSD)
Description: The Blind Spot Detection (BSD) is a system that measures the speed of and distance
from the following vehicles by using two magnetic wave radar sensors attached in the rear bumper.
The BSD detects vehicle within the blind spot zone and gives off an alarm (visual and audible). The
two magnetic radar sensors provide these functions for BSD:
• Senses other vehicles in the BSD zone and turns on the BSD warning lamp for the driver. The
warning lamp starts blinking when the driver turns on the turn signal lamp to enter the lane
where another vehicle is driving.
This bulletin describes the general operation of the BSD, provides a radar sensor troubleshooting
guide, and outlines the BSD system calibration method.
!Applicable Vehicles: All Vehicles Equipped with BSD
Warranty Information:
Normal Warranty Applies.
NOTE: If the BSD sensor(s) is confirmed to be damaged by external impact of a collision accident,
BSD sensor(s) replacement will not be covered under a warranty claim.

BSD RADAR SENSOR TROUBLESHOOTING GUIDE
If a vehicle has any of the active codes from below, follow the diagram below for troubleshooting
assistance:
• C270254 - Control Module Missing Calibration
• C270354 - Control Module Slave Calibration
• Check Vehicle Appearance:
Any deformation or accident
trace on the rear side of the
vehic le? Are there any meta llic
stickers on the rear bumper?
• Restore vehicle body including BSD
Sensor(s) mounti ng surface.
*** Refer to BSD Sensor Angle Specification
• Remove the metallic sticker(s).
~;;;;:;:::::= = ; '
YES
NO
Remove the rear bumper
• Check BSD Sensor(s) Surface:
Is BSD covered with dust
and contaminated?
• Re-install original BSD
Sensors
NO
• Check BSD Sensor(s)
Mounting Area and Bracket:
Any deformation at the rear
side of the vehicle?
• Restore vehicle body including
BSD Sensor(s) mounting surface.

BSD SYSTEM CALIBRATION METHOD
1.
If the BSD Sensor(s) is in need of
replacement, use the GOS to recalibrate
the Blind Spot Detection System.
2.
After completing the calibration procedure,
perform a OTC scan using the GOS to
confirm there are no DTC(s). If no DTC(s)
were incurred, then the automatic
calibration is completed.
3.
Confirm BSD system is functioning
normally.
NOTE: Follow the link from below for an
example of BSD operation:
