When the LDW-ECU is replaced, initialise the LDW camera before adjusting the LDW camera image.
Before the LDW camera image is adjusted, 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 adjust the LDW camera image
This procedure describes how to adjust the LDW camera input image.
note
The LDW camera image cannot be adjusted under unfavourable conditions such as snowfall. In such a case, you can eliminate a warning message in the combination meter by pressing the LDW switch for at least five seconds until the conditions improve. (A diagnosis code will not be erased.)
To recover the display, press the LDW switch for at least five seconds again.
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. (Start the engine.) 3.Select the M.U.T.-III screen menu as follows. (1)
Select "LDW" displayed on the "System selection" screen. (2)
Select "Special function." (3)
Select "Learning." (4)
Select "Calibration:Image adjustment." 4.The LDW indicator lamp in the combination meter will flash until the step below completes. 5.Drive the vehicle for at least five minutes cumulative at 40 km/h or more under the conditions below.
note
The ideal vehicle speed is 70 km/h or more. If you can drive the vehicle on a dry, stable and straight road at 70 km/h or more during day time, the image adjustment will be complete more quickly.
(1)
Road and environmental conditions should be so that the lane division lines should be clear. (2)
A cornering radius of the road should be 300 m or more. 6.After flashing, the lamp should go out or illuminate. 7.After checking the step above, turn the ignition switch "ON". If diagnosis code No. C1706 is stored, reset the LDW camera image compensation value, and then repeat the procedure. 8.The LDW camera image adjustment is complete.
