| Service Point Target Auto Calibration (SPTAC) |
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 Requried / Variant Coding Error" DTC set if it
is a replacement part delivered directly from supplier manufacturing.

Guidelines for Selecting a Suitable Target
In order for LDWS Service Calibration-Static routine to complete successfully, the following conditions are required:
| A. |
Target (SST : 09890-3V100) surface must be perpendicular to
the camera in both horizontal and vertical orientation to maintain
maximum of 1° roll. |
| B. |
Target to be mounted to rigid backer material to maintain flatness requirements. |
| C. |
Target must have reflective (not faded or poorly painted) markings not to represent lane features. |
| D. |
Target to be 30cm wide by 100cm tall. |
| E. |
Mounting area must NOT have cross hatch patterns or textual markings near the target. |
| F. |
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) |
Check of vehicle toe-in and tire pressure levels to ensure
proper alignment of the camera to the "world� before proceeding with
calibration is suggested. The vehicle is to be at nominal production
loading capacity when the calibration routine is running. |
| (2) |
Windscreen must be clean and serigraphy 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 (1.74m distance from the bumper) 




|
|
| (7) |
Technician ensures target placement location and check the "OK" message on the diagnostic tool (GDS). |
| (8) |
Clear the all of the DTCs. |
|
Drive Test
|
May not activate normally in case of 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 of distance with vehicle in front 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 normally 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. |
