Correction Overview

Need to calibrate the mounting angle of the BCW when a vehicle has a rear or a side collision with BCW system even just replacing a BCW bracket or BCW components.

Check before Correction

1.

When a failure code [C2702 (Master)] or [C2703 (Slave)] occurs, check the following before performing correction.

2.

Check the vehicle condition and whether the BCW unit or bracket is deformed (mounting angle, twisted vehicle body, etc.).

Checking the Vehicle
Normal
Abnormal (deformation of the bracket or bolted area)

3.

Check the nut tightening. Check if there is any foreign substance.

If you found any problem in the BCW unit, bracket, or nut tightening, correct the problem or replace the component. If there is no problem, mount the bumper back and perform BCW.

If a failure code is displayed or a warning lamp turns on even after performing BCW radar correction 5 times, replace the BCW unit.

Correcting the BCW Angle

1.

After replacing the BCW unit or bracket, with the bumper removed, use the BCW unit correction tool set (special tool : 09958-3T000) to perform angle correction.

  

Perform the task on a level place.

Perform the task after checking the tire pressure.

Perform the task indoors rather than outdoors so that you can identify the laser beam that is projected from a level laser (special tool : 09958-3T060).

The level laser (special tool : 09958-3T060) and measuring device (special tool : 09958-3T020) are sensitive to impact. If you are not using the tools, keep them in the respective cases.

2.

Attach a vertical plumb (special tool : 09958-3T010) on the hood, and lower the plumb (A) to the ground so that it passes through the center of the emblem.

3.

Install an optical receiver (special tool : 09958-3T020) below the plumb (A).

  

When you install the optical receiver (special tool : 09958-3T020), adjust the tripod (A) so that the optical receiver is level with the ground.

Check the level by looking through the level checking window (B).

Make sure that the plumb (D) is positioned above the hole (C) of the optical receiver as shown in the picture (A).

Make sure that the front of the optical receiver faces the rear of the vehicle.

4.

Attach a vertical plumb (special tool : 09958-3T010) on the trunk (or tailgate), and lower the plumb (A) to the ground so that it passes through the center of the emblem.

5.

Install the rear setting jig (special tool : 09958-3T030) so that its hole is placed directly under the plumb (A).

6.

Place the laser support (special tool : 09958-3T040) at a location '2m' away from the rear of the vehicle and install the level laser (special tool : 09958-3T060) above the laser support.

  

Move the level laser (special tool : 09958-3T060) slowly to left or right to form a center line.

When the laser beam goes through the hole of the rear setting jig and the level laser is placed at the center of the optical receiver, a buzzer sounds and the center line is formed on.

7.

Mount the BCW unit fixing adaptor (special tool : 09958-3T080) on the BCW unit and fix the level laser (special tool : 09958-3T070).

8.

Install an angle measuring plate (special tool : 09958-3T050) at a location where the center line laser beam (A) and the horizontal laser beam (B) cross each other.

9.

Measure the angle between the center line (A) of the angle measuring plate and the horizontal laser beam (B) using a digital protractor (special tool : 09958-3T090).

10.

Use a digital inclinometer (special tool : 09958-3T100) to measure the vertical angle of the BCW unit.

11.

Measure the horizontal and vertical angles of left and right BCW units. If the measured values deviate from the specified values, insert a washer (A) between the bracket of the BCW unit.

Specified Values

Horizontal Angle : 53 ± 2°

Vertical Angle : 90 ± 1°

Tightening torque Nut :

8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.1 lb·ft)

12.

After checking and correcting the BCW unit angle, perform the BCW radar correction procedure.

BCW Unit Alignment

1.

Rear bumper accident vehicles and vehicles that replaced BCW units must perform BCW unit alignment using KDS.

2.

Select "BCW Radar Calibration" procedure in BCW system.

3.

Perform the "BCW Radar Calibration" procedure according to the KDS screen message.
