When you need variant coding: | –
| Replace Front View Camera with a new one |
※ EOL Variant Coding and calibration required for new replacement |
Front View Camera Variant Coding
Front view camera variant coding makes it possible to operate functions for each vehicle type. If the variant coding differs from the vehicle specification, the "variant coding error" DTC is displayed.
| 1. | Procedure for coding variants | (1) | You should read the specification information for the front view camera that is installed in the vehicle before replacing it with a new front view camera. |
| (2) | Connect the cable of Diagnostic tool to the data link connector in driver side crash pad lower panel, and turn on the Diagnostic tool. |
| (3) | Select the 'S/W Management' and 'Car model'. 
|
| (4) | Select "System Identification". 
|
| (5) | Select "Variant Coding". 
|
| (6) | Enter the value of the specification read in procedure(4) in the new front view camera. |
|
| Service Point Target Auto Calibration (SPTAC) |
When you need calibration:
| –
| Front view camera is removed and mounted |
| –
| Replace front view camera with a new one |
| –
| Windshield glass changed |
| –
| front view camera coupler of the windshield glass is deformed |
Service Point Target Auto Calibration (SPTAC)
Front view camera SPTAC provides the method for the service technician to calibrate the camera by aligning the calibration target (SST: 09890-3V100) with the vehicle on a level ground.
If the calibration is not completed within the specified tolerance front view camera "System Out of Calibration" DTC is indicated.
| 1. | Method for Correct Alignment of Calibration Target In order to complete the calibration of the front view camera successfully, install the calibration target as follows: | –
| Install the target (SST: 09890-3V100) vertical to the ground and from the camera referring to the below tolerance angle. |
The tolerance ± 1° for the left and right gradient is very important and is sensitive to the flatness of the ground. Install the compensator vertically using the Level Laser (SST: 09958-3T060 or 09964-C1200). Arrange the Level Laser (A) on the center of the vehicle by installing it on the roof center above the vehicle's front windshield (same for both short and long distance calibrations) . 
Have the laser illuminate starting from the roof center and to all the way to the center of the target, passing through the emblem center. 
The level laser must be set to 'ON' and the holding (locking) function is not used. |
Target is mounted to rigid backer material to maintain flatness requirements. | –
| Target has reflective (not faded or poorly painted) markings that are unlike from lane features. |
| –
| Target is 30 cm wide and 100 cm tall. |
| –
| Mounting area must NOT have cross hatch patterns or textual markings near the target. |
| –
| Target should be well lit for optimal performance using non-fluctuating illumination. There shall be no continuous shadows cast on the target. |
| –
| The light should be directed toward the target front and the target front should be brighter than the target rear and target. |
|
|
| 2. | Service Point Target Auto Calibration(SPTAC) Procedure | 1) | It is recommended to check vehicle toe-in and tire pressure levels to ensure proper alignment of the camera to the "world" before proceeding with calibration. The vehicle to run the calibration routine is to be at nominal production loading capacity. |
| 2) | Windshield must be clean and silk-screen checked so that there is no blockage of the camera. |
| 3) | Service technician connects the diagnostic connector and starts the vehicle. The front view camera should not be activated by pressing the switch. |
| 4) | The service calibration routine may not run correctly if any system level fault is active. |
| 5) | If working with a replacement ECU: the service technician initiates the SPTAC Reset configuration. |
| 6) | Service technician either aligns the vehicle to the target or the target to the vehicle. a. Locate the bottom of the target 90cm from the ground (max. tolerance: 1cm). b. Locate so that the central axis of the target and the central axis of the vehicle match (max. tolerance: 3cm). c. Locate the short-distance target (A) so that it adheres by 0cm (B) to the bumper front (max. tolerance: 5cm). d. The location of the long-distance target (C) is 100cm (D) before the bumper (max. tolerance: 5cm). 
|
| 7) | Select Camera Calibration under Option of Global Diagnosis System (Diagnostic tool). 
|
| 8) | The technician should complete the short-distance calibration after checking the target location and "OK" message on the Diagnostic tool. 
|
| 9) | The technician should complete the long-distance calibration after checking the target location and "OK" message on the Diagnostic tool (conduct the calibration twice: short and long distances). If the distance 100 ± 5 cm (39.4 ± 2 inch) is different from the distance indicated on the Diagnostic tool, calibrate it according to the value indicated on the Diagnostic tool. 
|

|
Test Drive
| –
| Be sure to perform test drive to check for normal operation after performing calibration. |
| –
| Drive on straight road (of longer than 500 m) with 2 white or yellow lane marks at speed of over 40mph(60km/h), and check for the alert as you intentionally steer close to the lane mark. |
| –
| LKA operates properly if the lane mark segment space is less than 8 m. |
| –
| Perform test drive on car-only road or on a highway. |
|
| •
| The LKA is a system to prevent lane departure and assist steering. In any case, do not rely on the steering assist system, and the driver must take the necessary precautions to determine safety matters. |
| –
| Driver is responsible for being aware of surroundings and steering the vehicle for safe driving practices. |
| –
| Do not tinted window or attaching any types of coatings and accessories. |
| –
| Do not allow any water or liquid to contact the front view camera. |
| –
| Do not remove the front view camera parts and do not damage the front view camera by a strong impact. |
| –
| Do not put objects that reflect light on the crash pad. |
| –
| Excessive noise can make the LKA alarm sound unheard. |
|
