  • Be sure to check for DTCs before performing this procedure.
  • Illustrations may differ from the actual vehicle screen depending on the device settings and options. Therefore, some detailed areas may not be shown exactly the same as on the actual vehicle screen.

(a) Preparation for adjustment

(1) Park the vehicle with the steering wheel centered.

(2) Set a target bar behind the vehicle for optical axis adjustment of the television camera assembly (back camera position setting).

HINT:

Create a target bar for adjustment only when adjusting the optical axis of the television camera assembly.

HINT:

  • Set a piece of tape on the ground as the target bar for adjustment. Its width and length should be 20 to 30 mm (0.787 to 1.180 in.) and 1995 to 2005 mm (6.544 to 6.576 ft.), respectively. Check the color on the multi-display and choose a tape color which can be easily seen.
  • Before parking the vehicle, be sure to move the vehicle forward and in reverse to check that the tires are facing straight ahead with the steering wheel centered.
  • Check that the back door is fully closed.

(b) Start diagnostic mode.

NOTICE:

The following must be carried out with the engine started. Apply the parking brake, depress the brake pedal, check that the shift lever is in P, and ensure that the vehicle is not moving.

(1) Select "Function Check/Setting" on the "Service Menu" screen.

(2) Select "Camera Setting" on the "Function Check/Setting I" screen.

(3) Select "Next" on the "Signal Check" screen.

HINT:

  • When "CHK" (red) is displayed for any items on the "Signal Check" screen, selecting "Next" will not change the screen to the "Steering Angle Setting" screen.
  • When "CHK" (red) is displayed for any items on the "Signal Check" screen, perform inspections using the "Signal Check" screen.

(c) Steering Angle Setting

(1) Check that the steering wheel is centered (approximately +/- 5 degrees or less) and then select "STEERING CENTER MEMORIZE".

HINT:

When performing removal and installation, or replacement of the television camera assembly, steering angle setting is not required.

(2) After performing the steering center memorize operation, turn the steering wheel to the left and right lock positions and select "MAX STEERING ANGLE MEMORIZE". The maximum steering angle is then stored and the screen changes to the "Back Camera Position Setting" screen.

HINT:

  • The "Next" does not respond until the system memorizes the steering center and maximum steering wheel angle.
  • It is also possible to start by initially turning the steering to the right side.
  • When "MAX STEERING ANGLE MEMORIZE" is selected, a beep will sound to confirm that the adjustment values have been stored.
  • The adjustment values will not be stored unless "MAX STEERING ANGLE MEMORIZE" is selected after turning the steering wheel from lock to lock.
  • When "Back" is selected, the screen changes to the "Car Signal Check" screen without storing any values.
  • Even if no DTCs are detected, selecting "MAX STEERING ANGLE MEMORIZE" may not cause the adjustment values to be stored if the steering sensor is malfunctioning.
  • If selecting "MAX STEERING ANGLE MEMORIZE" does not cause the adjustment value to be stored after performing the steering angle setting procedure, replace the steering sensor.

(d) Back Camera Position Setting

HINT:

  • When adjusting the camera optical axis, "Back door is open. Do not use the rear view monitor when the back door is not completely closed." is displayed even after the back door has been closed.
  • When the back door is open, the "Back door is open. Do not use the rear view monitor when the back door is not completely closed." message will be displayed and camera position setting will not be possible.
  • If the "Back door is open. Do not use the rear view monitor when the back door is not completely closed." message is displayed even when the back door is closed, perform inspections according to Problem Symptoms Table (When adjusting the camera optical axis, "Back door is open. Do not use the rear view monitor when the back door is not completely closed." is displayed even after the back door has been closed).

(1) Perform vertical and horizontal position adjustment.

  • Select the directional switches D, E, F and G to move C so that the target adjustment bar is centered in C.

(2) Perform roll angle adjustment.

  • Select switches A and B to rotate C so that it is parallel to the target adjustment bar.

(3) Select "Next" on the "Back Camera Position Setting" screen.

(e) Back Verify Mode

(1) Check that (A) and the target adjustment bar are overlapping.

  • If the lines are not aligned, perform the "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" operations.
  • If (A) and the target adjustment bar are not aligned even if the tires are aligned straight ahead, perform the back camera position setting operation.

(2) Select "OK" to return to the "Function Check/Setting I" screen and complete the adjustment.

HINT:

  • The update is not completed until "OK" is selected.
  • When "OK" is selected, a beep will sound to confirm that the adjustment values have been stored.
  • The adjustment values are not stored until the beep has sounded.

(f) Finish diagnostic mode.

(g) Confirm steering angle adjustment.

HINT:

If the steering angle has been adjusted, confirm the steering angle adjustment on the parking assist monitor screen after finishing diagnostic mode.

(1) Check on the parking assist screen that the estimated course line moves until the steering wheel is fully turned to either the left or right.

HINT:

If the estimated course line stops moving before the steering wheel is fully turned to either the left or right, the steering angle adjustment values have not been stored correctly. In this case, perform "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" again.

3. BACK CAMERA POSITION SETTING (PROCEDURE 2)

HINT:

  • Be sure to check for DTCs before performing this procedure.
  • Illustrations may differ from the actual vehicle screen depending on the device settings and options. Therefore, some detailed areas may not be shown exactly the same as on the actual vehicle screen.
