This procedure provides a way to calibrate the camera by
having the service technician align the car to a well lit simulated
straight road target; preferably wall mounted.
The LDWS camera will have a "System Out of Calibration" DTC set if not operating within specified tolerances.
The LDWS will be supplied for field service replacement with
the "System Calibration Required / Variant Coding Error" DTC set if it
is a replacement part delivered directly from supplier manufacturing.
1.
Guidelines for Selecting a Suitable Target
In order for LDWS Service Calibration-Static routine to complete successfully, the following conditions are required:
–
Target (SST : 09890-3V100) surface must be perpendicular to
the camera in both horizontal and vertical orientation to maintain
maximum of 1° roll.
–
Target to be mounted to rigid backer material to maintain flatness requirements.
–
Target must have reflective markings (not faded or poorly painted) to represent lane features.
–
Target size is 30 cm wide by 100 cm high.
–
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.

Service Point Target Auto Calibration 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 camera module 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.
Bottom of the target is to be 90cm ±2cm from the ground and aligned with the camera lens horizontal axis.
b.
The target is placed along the vehicle’s longitudinal axis (centerline) within ±5cm of target center.
c.
The calibration target has to be placed at the 2.7m distance from the front wheel center.
(7)
After confirming the calibration target location in close distance, click "OK" on diagnostic device.
(8)
Technician ensures target placement location and checks the "OK" message on the diagnostic tool (KDS/GDS).
(9)
After confirming the calibration target location in remote distance, click "OK" on diagnostic device.
(Perform location calibration 2 times.)
(10)
Technician ensures target placement location and checks the "OK" message on the diagnostic tool (KDS/GDS).
(11)
Clear all of DTCs.
(12)
Turn off IGN and then on.
Drive Test
System may not activate properly in the following conditions:
–
In case lane is not visible due to glare or heavy rain.
–
In case the road is covered with snow.
–
In case puddle on the road surface reflects street light or head light from oncoming vehicle.
–
In case of blocking object such as sidewalk on the side of the road.
–
In case of there is trace of more than one lane due to road repair.
–
In case the distance to the foregoing vehicle is very short.
–
Be sure to run drive test to check normal operation after performing optical angle test.
–
Drive on straight line road (longer than 500m) 2 white or
yellow lane marks at speed over 60Km/h, and check when the alert is
activated as you intentionally steer close to the lane mark.
–
LDWS operates properly if the lane mark segment space is less than 8m.
–
LDWS activates at vehicle speed above 60Km/h.
–
Perform drive test on car-only road or on a highway.
