Camera calibration

Calibrate the camera-ECU according to the procedure below after the following operation is performed:

Replacement of the camera-ECU
Removal and installation/replacement of a camera
Any of the door or the tailgate, Outside rear-view mirror assembly (LH), (RH) is aligned.
The radiator grille assembly is deformed or loosened due to a collision accident.

How to check the image screen visually

note

To visually check one camera, two calibration markers (MB993003) are needed. So, you cannot check all the cameras simultaneously. Perform the visual inspection one after another.

Position the calibration markers (MB993003) as shown.
2.Press the multi around monitor operation switch on the steering wheel remote control switch (LH) to display the bird’s eye-view on the multivision display.

3.Check that the white lines, which are indicated by arrows, are shown as "straight line" on the bird’s eye-view image. (These lines should be also continuous in the same thickness.)

How to write learned value to the camera-ECU

When the camera is replaced, write a learned value to the new camera-ECU according to the procedure below.

1.Connect M.U.T.-III to the diagnosis connector (For how to connect M.U.T.-III, refer to the GROUP 00 - Diagnosis Function

2.Select "Write learned value(Changed ECU)" and then "Learned value Read&save" in the special functions for the multi-around monitor system to save the learned value, which is stored in the current camera-ECU, to the M.U.T.-III.

note

If the learned value cannot be read, replace the camera-ECU and then calibrate the camera.

3.Replace the camera-ECU (Refer to

4.Select "Write learned value(Changed ECU)" and then "Saved learned value writing" in the special functions to write the learned value, which is stored in the M.U.T.-III, to the camera-ECU.

5.If any problems are not found on the screen, the calibration is complete. If any problem is found, calibrate the camera.

How to calibrate a camera

caution

Do not interrupt a camera vision range while a camera-ECU is calibrated.

1.When the camera-ECU is replaced, first write a learned value to the camera-ECU.

2.Park the vehicle on a level surface.

note

Prevent sun light rays from interfering with the camera, otherwise the monitor screen will be reflected in white. Ideally, the brightness of a road surface should be low (such as black).

3.One person should sit on the driver’s seat.

4.Connect M.U.T.-III to the diagnosis connector (For how to connect M.U.T.-III, refer to the GROUP 00 - Diagnosis Function).

5.Position the calibration markers (MB993003) as shown.

Position the calibration markers in respect to the relevant camera only.

note

The calibration markers should be located in the permissible range. The range is within ± 3 cm and 1° from the standard position.

6.Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
7.Use the M.U.T.-III to calibrate the camera.

note

When you execute the calibration, all calibration-related data will be erased from the ECU.

8.Select "Calibration" in the "special function" for the multi-around monitor system.
9.Select a camera to calibrate on the service data located to the left of the calibration screen, and then press "OK".

Item No.	Item name	Contents
1	Front camera	Calibrate only the selected camera.
2	Rear camera
3	Left side camera
4	Right side camera

10.Select the camera being calibrated in the confirmation screen, and the press "OK".
11.Press the "OK" button after the execution screen is displayed.
12.When the calibration has completed successfully, "Completed" will be displayed on the service data item No.13.
13.If the calibration has failed, "Error" will be displayed on the service data item No.13. For details of errors, refer to "Calibration error table".
14.If any problems are not found on the screen, the calibration is complete. If any problems are found, repeat the calibration.

Calibration error table

Item No.	Item name	Error contents	Troubleshooting
14	Coding not comp detection flag	The variant coding for the ETACS-ECU has not been implemented.	The variant coding is carried out.
15	Door open detection flag	Any of the doors and tailgate are open.	Check that any of the doors and tailgate are closed. If no, close the door or the tailgate.
16	Front camera error flag	The front-view camera does not recognise either of the calibration markers precisely.	1. Check the vehicle conditions. Are prerequisites for the calibration satisfied? Is the vehicle parked in a correct position? Is the camera lens contaminated? 2. Check the calibration markers. Are the calibration markers positioned correctly? Are the calibration markers contaminated? Is any of the calibration markers hard to see due to a sunlight refection? 3. Repeat the calibration.
17	Rear camera error flag	The rear-view camera does not recognise either of the calibration markers precisely.
18	Left side camera error flag	The side-view camera (LH) does not recognise either of the calibration markers precisely.
19	Right side camera error flag	The side-view camera (RH) does not recognise either of the calibration markers precisely.
20	Flash ROM writing error flag	Internal malfunction of camera-ECU	1. Repeat the calibration. 2. If any error code is displayed again, replace the camera-ECU (Refer to ). 3. Repeat the calibration.
21	SD-RAM error flag
22	EEPROM writing error flag
