Surround View Camera Calibration

  1. Determine the center line of the vehicle by suspending the Plumb Line (LAM09-06) against the center of the rear vehicle "V" logo and let it naturally drop to the ground. Lightly flick the string with your finger several times to confirm the string is perpendicular to the ground. Mark the ground with a Cross Sticker to indicate the Rear Center Point of the vehicle - Point (B).

  2. Place the Five-Line Laser Instrument (LAM09-01) at Point (B). The Logo on the Five-Line Laser Instrument should be facing towards the front of the vehicle. Ensure the red dot underneath the Five-Line Laser Instrument is aligned with the Cross Sticker at Point (B).
  3. Suspend the Plumb Line (LAM09-06) against the centre of the front vehicle "V" logo and let it naturally drop to the ground. Lightly flick the string with your finger several times to confirm the string is perpendicular to the ground. Mark the ground to indicate the Front Center Point of the vehicle Point (A) with one of the Cross Stickers provided.
  4. Place the Laser Reflector (LAM09-03) parallel to the vehicle and ensure the reflective stripe is aligned with Point (A).

  5. Place the Auxiliary Mirror (LAM09-04) at the rear of the vehicle, approximately located at (1). Angle the Auxiliary Mirror appropriately so that the Laser Reflector at the front of the vehicle can be viewed without needing to lie on the ground.
  6. Adjust the support legs of the Five-Line Laster Instrument (LAM09-01) to ensure it is level. Turn on the laser beams of the Five-Line Laser Instrument (LAM09-01).
  7. Observe the position of the laser beam with the auxiliary mirror LAM09-04. Rotate the fine tuning knob (2) of the 5-Line Laser Instrument (LAM09-01) to ensure the longitudinal laser beam aligns with the reflective stripe of the Laser Reflector (LAM09-03). The dotted line (P) now represents the Centre Line of the Vehicle.

  8. Use a Tape Measure to measure cross car a distance of 1050 mm in both directions. Mark these points with Cross Stickers as Points (Bl) and (B2).
  9. Move the 5-Line Laser Instrument (LAM09-01) to Point A and the Laser Reflector (LAM09-03) to Point (B). Ensure the 5-Line Laser is still level and the laser beam aligns with the reflective stripe.

  10. Use a Tape Measure to measure cross car a distance of 1050 mm in both directions. Mark these points with Cross Stickers as Points (J1) and (J2).
  11. Position the Surround View Camera Mats (LAC04-32-1) approximately along either side of the car with the narrower (200 mm) border closest to the vehicle. Align the inner edge of the Left Side Mat with (J1) and (B1). Align the inner edge of the Right Side Mat with (J2) and (B2).

    Alignment Note: The fore-aft position of the mats will be adjusted in the next steps 

  12. Place the L shaped bracket (LAM09-05) in line with the centre hub of the Right Front Wheel. Measure rearwards a distance of 316 mm. Adjust the fore-aft position of the Right Side Mat (LAC04-32-1) so that distance from the Axle Centre line to grey marking (Distance X) is 316 mm. Ensure the inner edge of the mat is still aligned with (B2) and (J2).
  13. Repeat this measurement on the Left Side of the car again ensuring Distance X is 316 mm and the Left Side Mat (LAC04-32-1) is aligned with (B1) and (J1).

  14. Position the Front and Rear Mats (LAC04-32-2) in the gap between the Side Mats (LAC04-32-1) at the front and rear of the vehicle. Ensure the Label Tabs on the Front and Rear Mats (LAC04-32-2) are positioned on the edge closest to the vehicle.

    Calibration note: Ensure the wheel base and the edge of the middle mat patches (distance X) is set to 316 mm.

  15. Align the outer corners of the Front and Rear Mats (LAC04-32-2) with the inner corners of the long Side Mats (LAC04-32-1) - (no measurements necessary).
    IMPORTANT: Ensure the Front and Rear Mats are positioned with the Label Tabs on the edge closest to the vehicle
  16. Refer to DIAGNOSTICS, PROGRAMMING & SETUP USING IDS IN SERVICE Follow IDS instructions to trigger the MHU module "SVM Calibration" procedure for the Surround View Camera System.
  17. If error codes are reported on IDS, refer to the table below and adjust the calibration setup as required.
  18. IDS will confirm when Surround View Camera Calibration is complete.
  19. Finally complete a Diagnostic Trouble Code check to ensure the vehicle is operating correctly.
