How to initialise the LDW camera


caution
  • When the LDW-ECU is replaced, first initialise the LDW camera, and then adjust the LDW camera image.
  • Before the LDW camera is initialised, check the LDW camera mounted surface on the windshield for scratch, cracks, contamination or drain drops and check that the LDW-ECU is installed correctly.

How to initialise the LDW camera
This procedure describes how to adjust the LDW camera image and how to initialise the rain sensor and the light sensor by using a white paper, which covers the whole the LDW camera, and a suitable hand torch of at least 500 lux.
caution
  • The white paper should penetrate light. Do not a ruled-line or contaminated paper.
  • The hand torch should have a wide lighting range.
1.Turn the ignition switch "OFF" and then connect the M.U.T.-III to the diagnosis connector (For how to connect the M.U.T.-III, refer to GROUP 00 - Diagnosis function).
2.Turn the ignition switch to the "ON" position. (Do not start the engine.)
3.From the system selection screen of M.U.T.-III, select "Lane Keep".

4.Place a white paper on the exterior side of the windshield glass (on the LDW camera mounted surface). Then shine a bright light directly to it.
caution
  • You should hold a certain distance between the hand torch and the windshield glass.
5.Select items from the M.U.T.-III while keeping the condition above:
(1) Select "Special function."
(2) Select "Learning."
(3) Select "Calibration:Camera internal data."
6.The LDW indicator lamp in the combination meter should flash.
7.Then it should go out once and then come on again.
8.Wait for ten seconds. * If diagnosis code No. C1703 or B1952 is set, repeat the procedure from Step 3.
note *: The rain sensor will be initialised automatically during this ten-second period.
9.The LDW camera has been initialised completely.

How to reset the LDW camera initialisation data
If you replace the windshield glass or initialise the ECU again, first reset the LDW camera initialisation data according to this procedure before the initialisation.
1.Turn the ignition switch "OFF" and then connect the M.U.T.-III to the diagnosis connector (For how to connect the M.U.T.-III, refer to GROUP 00 - Diagnosis function).
2.Turn the ignition switch to the "ON" position. (Do not start the engine.)
3.Select the M.U.T.-III screen menu as follows.
(1) Select "Lane Keep" displayed on the "System selection" screen.
(2) Select "Special function."
(3) Select "Reset."
(4) Select "Decalibration:Camera inter. data."
4.After the reset is complete, diagnosis code No. C1703 will be set and the LDW warning lamp in the combination meter will illuminate.
