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.
Applicable Vehicles: All Vehicles Equipped with BSD/BCW
Warranty Information:
Normal Warranty Applies.
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.
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.

BSD/BCW RADAR VERTICAL AND HORIZONTAL ANGLE MEASUREMENT PROCEDURE
1.
Ensure the vehicle is on a flat even surface.
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.
4.
Find the center point of the front of the vehicle as illustrated in the picture.
Use the center point of the front Hyundai emblem.
Place masking tape underneath the yellow vertical plumb to prevent scratching the paint when removing the tool from the vehicle body.
NOTICE
Masking Tape
String Center of
Emblem
This procedure is best performed in an indoor environment for ease of viewing the laser light.
NOTICE
If the vertical angle(s) is not within specification, then address it first before continuing with measuring the horizontal angles.

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.
Place masking tape underneath the yellow vertical plumb to prevent scratching the paint when removing the tool from the vehicle body.

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.
