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 MFC will have a "System Out of Calibration" DTC set if not operating within specified tolerances.

Information 

When you need calibration:

• MFC is removed and mounted
• Replace MFC with a new one

* EOL Variant Coding and calibration required for new replacement

• Windshield glass changed
• MFC coupler of the windshield glass is deformed

1. Guidelines for Selecting a Suitable Target

   In order for LKAS Service Calibration-Static routine to complete successfully, the following conditions are required:

   • Target (SST: 09890-3V100) surface is perpendicular to the camera in both horizontal and vertical orientations to maintain maximum of 10° horizontal, 5° vertical and 1° roll.
   • 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.
   • Bottom of the target is 90 ± 1 cm (35.4 ± 0.4in.) from the ground and aligned with the camera lens horizontal axis.
   • 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.
      1. Bottom of the target is 90 ± 1 cm (35.4 ± 0.4in.) from the ground
      2. The target (A) is placed along the vehicle's longitudinal axis (centerline) within ±3 cm (±1.2 in.) of target center.
      3. The position of target (A) in short distance is 0 ± 5 cm (0 ± 2 in.) (B) in front of front bumper. (Maximum error: 5cm)
      4. The position of target (A) in long distance is 100 ± 5 cm (39.4 ± 2 in.) (B) in front of front bumper. (Maximum error: 5cm)

   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 (GDS).
