LANE DEPARTURE WARNING SYSTEM
 The target may not be detected when there is the same pattern of black and white as the target when
the pattern is within 1 m (3.28 ft) from either si de and upward/downward position from the target. (It
is desirable that the vehicle is positioned on the opposite side of a single-color wall.)
1. Mark a point at the center of lateral surface of each wheels (“A”,
“B”, “C” and “D”).
NOTE:
Dangle a string with a cone from the fender so as to pass
through the center of wheel, and t hen mark a point at the center
of lateral surface of wheels.
2. Draw a line passing through points “A” and “B” on the left side of vehicle (line “LH”).
NOTE:
Approximately 4 m (13.12 ft) or more from the forward end of
vehicle.
3. Mark points on the line “LH”, at the positions 3850 mm (151.57 in) from the point “A” (“E”).
4. Draw a line passing through the points “C” and “D” on t he right side of vehicle as with the step 2 (line
“RH”).
NOTE:
Approximately 4 m (13.12 ft) or more from the forward end of vehicle.
5. Mark points on the line “RH”, at the positions 3850 mm (151.57 in) from the point “C” (“F”).
6. Draw a line passing through the points “E” and “F” (line “FW”).
7. Mark point at the center of the point “E” and “F”, on the line
“FW”.
CAUTION:
Make sure that “E” through “X” is equal to “F” through “X”.
8. Position the center of the right target to the point of “X”.

Measure the wheel arch height. And calculate “Dh”.
NOTE:
“Dh” may be calculated as a minus value.
AIMING ADJUSTMENT
Operation Procedure
CAUTION:
 Perform the adjustment under unloaded vehicle condition.
 LDW indicator is turned off after the remo val/installation, and blinks after replacement.
NOTE:
When the DTC (C1B01 CAM AIMING INCMP) is disp layed on CONSULT-III screen, perform the aiming
adjustment after erasing the DTC.
1. Select “Work Support” on LDW with CONSULT-III.
2. Select “AUTO AIM”.
3. Confirm following.
a. The target should be accurately placed.
b. The vehicle should be stopped.
4. Select “Start” to perform aiming.
CAUTION:
Never Select “Start” when the target is not placed.
5. Input “Dh”, and then select “Start”. NOTE:
Check the value “Dh”. Refer to "VEHICLE HEIGHT CHECK".
CAUTION:
Never change “Ht” and “Dt”.
6. Check it display item.
a. “Normally Completed” is displayed, then selecting “Completion”.
b. Perform the following services when displa yed “SUSPENSION” or “ABNORMALLY COMPLETED”.
NOTE:
Replace camera unit if “SUSPENSION” is repeatedly indicated though the above tw o service is performed.
7. Check if “Normally Completed” is displayed and close the aiming adjustment procedure by selecting
“End”.
Check After The Adjustment
1. Perform self-diagnosis of LDW camera unit. Refer to DI-81, "CONSULT-III Function (LDW)".
2. Test the LDW system operation by running test. Refer to DI-71, "
Action Test".
Dh [mm] = (Hfl + Hfr)
÷ 2 − 840
where, Hfl: Front left wheel arch height [mm]
Hfr: Front right wheel arch height [mm]
