Parking Assist Monitor System (For Camera Built-In Ecu) Calibration

The parking assist monitor system can be adjusted using diagnostic mode.

If the following operations are performed, it is necessary to perform adjustments and checks using diagnostic mode.

HINT:

The adjustment values stored while performing parking assist monitor system calibration are stored in the rear television camera assembly.

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 rear television camera assembly (back camera position setting).
   

   HINT:

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

   HINT:

   1. Set a piece of tape on the ground as the target bar for adjustment. Its width and length should be 20 to 30 mm (0.79 to 1.18 in.) and 1995 to 2005 mm (6.54 to 6.58 ft.), respectively. Check the color on the multi-display and choose a tape color which can be easily seen.
      
   2. 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.
      
   3. Check that the back door is fully closed.
      

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 "Car Signal Check" screen.
   

   HINT:

   1. When "CHK" (red) is displayed for any items on the "Car Signal Check" screen, selecting "Next" will not change the screen to the "Steering Angle Setting" screen.
      
   2. When "CHK" (red) is displayed for any items on the "Car Signal Check" screen, perform inspections using the "Car Signal Check" screen (LandCruiser RM000003WVZ06PX.html).
      

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 rear 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:

   1. The "Next" does not respond until the system memorizes the steering center and maximum steering wheel angle.
      
   2. It is also possible to start by initially turning the steering to the right side.
      
   3. When "MAX STEERING ANGLE MEMORIZE" is selected, a beep will sound to confirm that the adjustment values have been stored.
      
   4. The adjustment values will not be stored unless "MAX STEERING ANGLE MEMORIZE" is selected after turning the steering wheel from lock to lock.
      
   5. When "Back" is selected, the screen changes to the "Car Signal Check" screen without storing any values.
      
   6. Even if no DTCs are detected, selecting "MAX STEERING ANGLE MEMORIZE" may not cause the adjustment values to be stored if the spiral with sensor cable sub-assembly is malfunctioning.
      
   7. If selecting "MAX STEERING ANGLE MEMORIZE" does not cause the adjustment value to be stored after performing the steering angle setting procedure, replace the spiral with sensor cable sub-assembly (LandCruiser RM000002O8X02DX.html).
      

Back Camera Position Setting

HINT:

1. 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.
   
2. 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.
   
3. 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) (LandCruiser RM0000035D707EX.html).
   

1. Perform vertical and horizontal position adjustment.
   

   1. Move the circle (A) left, right, up and down by selecting the buttons (C), (D), (E) and (F) so that the left end of Target Adjustment Bar for Back Camera Position Setting is positioned within the center of the circle (A) (center of the inner red circle).
      

2. Perform roll angle adjustment.
   

   1. Rotate the bar (B) by selecting the buttons (G) or (H) so that the bar (B) becomes parallel to Target Adjustment Bar for Back Camera Position Setting.
      

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

Back Verify Mode

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

   1. If the lines are not aligned, perform the "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" operations.
      
   2. 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:

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

Finish diagnostic mode.

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.
