BLIND SPOT DETECTION (BSD) OR
BLIND-SPOT COLLISION WARNING (BCW)
This TSB supersedes 18-BE-004-2 to include the notice of down level parts availability and
BSD/BCW warranty coverage information.
Description: The Blind Spot Detection (BSD) or Blind-Spot Collision Warning (BCW) 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/BCW 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/BCW:
 Senses other vehicles in the BSD/BCW zone and turns on the BSD/BCW warning lamp for the
driver. The warning lamp starts blinking, along with an audible sound, 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/BCW, provides a radar sensor
troubleshooting guide, and outlines the usage of the BSD/BCW system angle measurement tool.
NOTICE
In cases of DTC C2702/C2703 and the bracket(s) is confirmed damaged, then only replace
the bracket(s). See TSB 18-BE-005-1 for available down level BSD/BCW replacement parts.
Applicable Vehicles: All Vehicles Equipped with BSD/BCW
Warranty Information:
Normal Warranty Applies.
NOTICE
In cases of DTC C2702/C2703, if the BSD/BCW sensor(s) is confirmed to be damaged by
external impact or collision accident, BSD/BCW sensor(s) replacement will not be covered
under warranty.

BSD/BCW RADAR VERTICAL AND HORIZONTAL ANGLE MEASUREMENT PROCEDURE
1.
Ensure the vehicle is on a flat even
surface.
NOTICE
This procedure is best performed in an
indoor environment for ease of viewing
the laser light.
2.
Follow the shop manual to remove the rear
bumper.
3.
Use the digital inclinometer to measure the
vertical angle from each radar sensor and
confirm if it is within specification.
If the vertical angle from both radar
sensors are within specification then
proceed to the next step to measure the
horizontal angle.
NOTICE
If the vertical angle(s) is not within
specification, then address it first
before continuing with measuring the
horizontal angles.
4.
Find the center point of the front of the
Masking Tape
vehicle as illustrated in the picture.
Use the center point of the front Hyundai
emblem.
NOTICE
Place masking tape underneath the
yellow vertical plumb to prevent
scratching the paint when removing
the tool from the vehicle body.

5.
Once the plumb and string are centered
with the front Hyundai emblem, place a
piece of tape under the plumb bob, then
use a permanent marker and mark the
center point as illustrated in the picture.
6.
Remove the vertical plumb from the front of
vehicle.
7.
Find the center point of the rear of the
vehicle as illustrated in the picture.
Use the center point of the rear Hyundai
emblem.
NOTICE
Place masking tape underneath the
yellow vertical plumb to prevent
scratching the paint when removing
the tool from the vehicle body.

8.
Once the plumb and string are centered
with the rear Hyundai emblem, place a
piece of tape under the plumb bob, then
use a permanent marker and mark the
center point as illustrated in the picture.
9.
Tie the green string to the black rubber
ring.

10. Carefully throw the black rubber ring
attached to the green string from under the
rear of vehicle to the front. Align the green
string to the front center point (a) and the
rear center point (b) and tape down the
string at about 6 ft. away from the rear of
the vehicle (c) as illustrated in the picture.
11. Attach the fixing adapter to the radar
sensor.
To attach the tool, align it vertically to the
radar sensor and hand tighten the two
handles by turning them clockwise.

12. Insert the horizontal measuring device, turn
the laser ON (select the switch which
displays a line), and aim the light to cross
the string.

Ensure the metal side is placed against the
fixing adapter.

13. Use the digital protractor to measure the
projected laser line to the green string to
find the horizontal angle as illustrated in the
picture.
In the example to the right the angle is 36.8
degrees.
Measure the angle for both right and left
sides.

14. Connect the mobile GDS and select “BSD
Radar Calibration”. Follow the guided
instructions on the mobile GDS for further
assistance with validating the BSD/BCW
angles.
15. After completing the angle measurement
procedure, perform a DTC scan using the
GDS to confirm there are no DTC(s). If no
DTC(s) were incurred, then confirm
BSD/BCW system is functioning
normally.
