MFC Variant Coding
MFC 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 MFC
that is installed in the vehicle before replacing it with
a new MFC.
|
| (2) |
Select specification information from G-SCAN's additional
function.
|
| (3) |
Enter the value of the specification read in procedure(2)
in the new MFC.
|
|
| Service Point Target
Auto Calibration (SPTAC) |
When you need calibration:
| – |
MFC is removed and mounted
|
| – |
Replace MFC with a new one
|
| – |
Windshield glass changed
|
| – |
MFC coupler of the windshield glass is deformed
|
Service Point Target Auto Calibration (SPTAC)
MFC 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 MFC "System
Out of Calibration" DTC is indicated.
| 1. |
Method for Correct Alignment of Calibration Target
In order to complete the calibration of the MFC 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 MFC 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 (GDS).
|
| 8) |
The technician should complete the short-distance calibration
after checking the target location and "OK" message on the
GDS.
|
| 9) |
The technician should complete the long-distance calibration
after checking the target location and "OK" message on the
GDS (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 GDS,
calibrate it according to the value indicated on
the GDS.
|
|
|
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 60km/h (64mph), 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 may not activate properly in the following conditions
The LKA may not activate properly when:
| – |
It is difficult to distinguish the lane from the road due
to dust built up on the lane.
|
| – |
It is difficult to distinguish the color of the lane line
from the road.
|
| – |
There is a mark that looks like a lane line near the line.
|
| – |
The lane line is indistinct or damaged.
|
| – |

|
|
|
The LKA may not activate properly in the following conditions:
| • |
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 steer the steering wheel suddenly when the steering
wheel is being assisted by the system.
|
| – |
LKA helps prevent the driver from moving out of the lane
unintentionally by assisting the driver’s steering.
