Repair Procedures

Removal

1
Disconnect the negative (-) battery terminal.
2
Remove the front camera module cover (A).
3
Remove the front camera module (B) after disconnecting the connector (A).

Installation

Install in the reverse order of removal.

Inspection

Diagnosis Using KDS

1
In the body electrical system, faults can be quickly diagnosed using the Korean Diagnostic System (KDS).

The Diagnostic System (KDS) provides the following information.
1. Self-diagnosis: check for malfunction and diagnostic trouble code (DTC).
2. Current Data: Check the system input/output status.
3. Operation check: Check the operating status of the system.
4. Special Function: Control of other functions, including parameter setting and zero point adjustment.
2
Select "Vehicle Model" and "Multi-Function Camera (MFC)" to inspect using the tester.
3
Select the "Current Data" menu to view the current input/output data status.

Input/output data for the Lane Keeping Assist (LKA) system can be checked.

Adjustment

Option Coding Procedures

1
When the front camera module is replaced with a new one, option coding is required because the vehicle must learn the option specifications of the original vehicle.
2
Complete the option coding procedure by following the instructions on the connected KDS screen.

Service Point Target Automatic Calibration (SPTAC)

The SPTAC front view camera calibration provides a procedure for calibrating the camera by aligning the calibration target (SST: 09890-3V100) with the vehicle on a level surface.

If calibration is not completed within the specified tolerance, the front view camera displays a "System Out of Calibration" DTC.

1
Correct Alignment Method of the Calibration Target
1. To perform the front view camera calibration successfully, install the calibration target as follows:
  - Install the target (SST: 09890-3V100) perpendicular to the ground and facing the camera, referring to the tolerance angles below.
  Caution
  - The ±1° tolerance for the left and right gradient is very important and is sensitive to the flatness of the ground.
  - Install the compensator vertically using a laser level (SST: 09958-3T060 or 09964-C1200).
  - Position the laser level (A) at the center of the vehicle, aligned with the center of the roof above the windshield (same for both short and long distance calibration).
2. Project the laser from the center of the roof to the center of the target, passing through the center of the emblem.
  
  * The laser level must be set to "ON", and the hold (lock) function must not be used.
  NOTE
  - Mount the target on rigid backing material to meet the flatness requirements.
  - The target must have reflective markings (not faded or poorly painted) that differ from lane markings.
  - Target is 30 cm wide and 100 cm high.
  - The installation area must NOT have hatching or text markings near the target.
  - The target must be well lit with constant lighting for optimal operation. There must be no solid shadows cast on the target.
  - The light must be directed at the target; the front of the target must be brighter than the rear of the target and the target.

Service Point Target Automatic Calibration (SPTAC) Procedure

It is recommended to check the vehicle wheel alignment and tire pressure to ensure correct camera alignment to the "world" before proceeding with calibration.

The vehicle used for the calibration procedure must be at its rated production load capacity.
The windshield must be clean and free of silkscreen so that there is no obstruction to the camera.
The service technician connects the diagnostic connector and starts the vehicle. The MFC must not be activated by pressing the switch.
The service calibration procedure may not work correctly if a system-level fault is active.
When working with a replacement ECU: the service technician initiates the SPTAC reset configuration.

The service technician aligns either the vehicle to the target or the target to the vehicle.

a.	Locate the bottom of the target at a height of 90 cm from the ground (max. tolerance: 1 cm). NOTE Position so that the center axis of the target and the center axis of the vehicle coincide (max. tolerance: 3 cm).

b.	Locate the near target (A) so that it is 0 cm (B) from the front of the bumper (max. tolerance: 5 cm).

b.	Locate the far target (C) at 100 cm (D) in front of the bumper (max. tolerance: 5 cm). NOTE The horizontal direction tolerance angle of the target is ±10°. The vertical direction tolerance angle of the target is ±5°. The tolerance angle of the target at the front center is ±1°.

The service technician must perform short-distance calibration after checking the target location and the "OK" message on the KDS.
The service technician must perform long-distance calibration after checking the target location and the "OK" message on the KDS (perform calibration twice: short and long distance).
Clear the diagnostic trouble codes.
Restart after turning off the engine.

Test Drive

NOTE

LKA may not activate properly under the following conditions.

LKA may not activate properly if:

It is difficult to distinguish the lane from the road due to dust accumulated on the lane.
It is difficult to distinguish the lane line color from the road.
There is a marking near the line that resembles a lane line.
The lane line is unclear or damaged.
The number of lanes increases or decreases, or lane lines intersect (driving through a toll gate, toll plaza, road merge, or diverging area, etc.).
There are more than two lanes.
The lane is very wide or narrow.
The lane is not visible due to snow, rain, stains, puddles, or other factors.
Shadows of objects (median strip, guardrail, noise barriers, etc.) surrounding the road are cast on the lane.
The lane is congested or is replaced by a structure in a building area.
There are indications on the road surface, such as a crosswalk or road signs.
The lane inside a tunnel is covered with dust or oil.
The outside brightness changes abruptly, such as when entering or exiting a tunnel.
The headlights are not on at night or in a tunnel, or the illuminance level is low.
There is a boundary structure.
Light, such as from a street lamp, sunlight, or the headlights of an oncoming vehicle, is reflected from water on the road.
Driving with the sun in front of you.
Driving in a bus-only lane or in the left/right lane.
The lane suddenly disappears in certain places, such as at an intersection.
The distance to the vehicle ahead is very short, or vehicles are blocking the lane line.
Driving on a steep slope or a sharp curve.
The vehicle is vibrating excessively.
The temperature around the inside rearview mirror is high due to direct sunlight.
The lens or windshield is covered with foreign substances.
The sensor cannot detect the lane due to fog, heavy rain, or heavy snow.
The windshield is fogged up due to humid air inside the vehicle.
Placing anything on the crash pad.
