Hyundai Kona: MFC (Multi-Function Camera) / Repair Procedures

Variant Coding

MFC Variant Coding MFC variant coding allows the functions to be configured for each vehicle type. If the variant code differs from the vehicle specification, the DTC "Variant Coding Error" is displayed.

Variant Coding Procedure
1. Read the specification information of the MFC installed in the vehicle before replacing it with a new MFC.
2. Select the specification information from the additional function.
3. Enter the specification value read in step (2) into the new MFC.

Service Point Target Automatic Calibration (SPTAC)

When calibration is required:

MFC Removal and Installation
Replace the MFC with a new one.
Windshield Replaced
MFC Windshield Bracket Deformed

MFC Service Point Target Automatic Calibration (SPTAC) SPTAC provides the service technician with a method to calibrate the camera by aligning the calibration target (SST: 09890-3V100) with the vehicle on level ground. If calibration is not completed within the specified tolerance, the DTC "System Out of Calibration" is displayed in the MFC.

1
Calibration Target Alignment Method For successful MFC calibration, install the calibration target as follows:
- Install the target (SST: 09890-3V100) perpendicular to the ground and at the camera-related lower corner tolerance.
CautionThe tolerance of ±1° for the left and right gradient is very important and sensitive to ground levelness. Set the target vertically using a laser level (SST: 09958-3T060 or 09964-C1200). Position the laser level (A) at the center of the vehicle, aligned to the center of the roof above the front windshield (same for both near and far calibration).
Let the laser illuminate from the center of the roof along the entire path 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.
NOTEThe target must be attached to a rigid support material to maintain flatness.
- 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.
- Light must be directed at the front of the target, and the front of the target must be brighter than the back of the target.

Service Point Target Automatic Calibration (SPTAC) Procedure
1. It is recommended to check the vehicle toe alignment and tire pressure levels to ensure correct camera alignment to the "world" before starting calibration. The vehicle must be at nominal production load capacity when starting the calibration procedure.
2. The windshield must be clean and free of silkscreen so that there is no camera obstruction.
3. The service technician connects the diagnostic connector and starts the vehicle. The MFC must not be activated by pressing the switch.
4. The service calibration procedure may not operate correctly if any system-level fault is active.
5. When working with a replacement ECU: the service technician initiates the SPTAC reset setting.
6. The service technician aligns either the vehicle to the target or the target to the vehicle. a. Position the lower edge of the target at 90 cm from the ground (max. tolerance: 1 cm). b. Position so that the center axis of the target and the center axis of the vehicle coincide (max. tolerance: 3 cm). c. Position the near target (A) at 0 cm (B) from the front of the bumper (max. tolerance: 5 cm). d. Position the far target (C) at 100 cm (D) from the front of the bumper (max. tolerance: 5 cm).
7. Select "Camera Calibration" in the Global Diagnostic System (GDS).
8. The service technician must perform short-distance calibration after checking the target location and the "OK" message on the GDS.
9. The service technician must perform long-distance calibration after checking the target location and the "OK" message on the GDS (perform calibration twice: short distance and long distance).
  NOTEIf the distance of 100 ± 5 cm (39.4 ± 2 in.) differs from the distance specified in the GDS, calibrate according to the value specified in the GDS.

Test Drive

NOTELKA 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 color of the lane line 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 cross (driving through a toll gate, toll plaza, road merge or divergence 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 overlapped or replaced by a structure at a construction site.
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.
Headlights are not on at night or in a tunnel, or the light level is low.
There is a boundary structure.
Light such as street lamps, sunlight, or oncoming vehicle headlights is reflected from water on the road.
Driving with the sun in front of you.
Driving in a lane reserved only for buses, or to the left/right of a lane.
The lane suddenly disappears in certain places, such as at an intersection.
The distance to the vehicle ahead is very short, or the vehicle is driving and obscuring 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.

NOTELKA may not activate properly in the following cases:

LKA is a system that helps prevent unintentional lane departure by assisting steering. Never rely solely on the steering assistance of the system; the driver must take the necessary precautions to identify safety issues.
The driver is responsible for being aware of the surroundings and controlling the vehicle for safe driving.
Do not turn the steering wheel abruptly while the system is assisting steering.
LKA helps prevent the driver from unintentionally departing the lane by assisting the driver in steering the vehicle.
LKA does not operate if the camera cannot detect the lane or if the vehicle speed does not exceed 64 km/h.
Do not disassemble the MFC to tint windows or attach any kind of film or accessories.
Do not allow water or liquid to get on the MFC.
Do not remove MFC components or damage the MFC by applying strong impact.
Do not place light-reflecting objects on the airbag cover.
Excessive noise may prevent the LKA warning signal from being heard.

Intelligent High Beam (SHB)

NOTEThe system may not operate normally under the following conditions.

When the light from an oncoming or preceding vehicle is not detected due to a damaged lamp, being hidden from view, etc.
When the lamp of an oncoming or preceding vehicle is covered with dust, snow, or water.
When the light from an oncoming or preceding vehicle is not detected due to exhaust gas, smoke, fog, snow, etc.
When the windshield is covered with foreign matter such as ice, dust, or fog, or is damaged.
When there is a lamp of similar shape to the lamp of the vehicle ahead.
When visibility is poor due to fog, heavy rain, or snow.
If the headlamp is not repaired or replaced at an authorized dealer.
If the headlamp aim is not adjusted properly.
When driving on a narrow winding road or an uneven road.
When driving downhill or uphill.
When only part of the vehicle ahead or a curved road is visible at an intersection.
When there is a traffic light, reflective sign, flashing sign, or mirror.
When road conditions are poor, such as wet or snow-covered roads.
When the headlamps are off but the fog lamps are on.
When a vehicle suddenly appears from around a curve.
When the vehicle leans due to a flat tire or when towing.
When the LDW/LKA warning lamp illuminates.
Replace the MFC with a new one.
