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)
