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]

Content Conditions and Measures
Hypoid gear  If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.
 If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive gear and drive pinion as a set.
Bearing  If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear  If any cracks or damage on the surface of the tooth is found, replace.
 If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer  If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal  Whenever disassembled, replace.
 If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
Differential case  If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange  If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

9. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting shim to adjust. Refer to FFD-39,
"Inspection and Adjustment".
10. Record the total amount of shim thickness required for the cor- rect carrier side bearing preload.
Pinion Gear Height
If the hypoid gear set has been replaced, se lect the pinion height adjusting washer.
1. Use the formula below to calculate pinion height adjusting washer thickness.
2. Select the proper pinion height adjusting washer. Refer to FFD-39, "
Inspection and Adjustment".
If impossible find the desired thickness of washer, us e washer with thickness closest to the calculated
value.
Pinion Bearing Preload
 Assemble the drive pinion parts if they are disassembled. Refer to "Drive Pinion Assembly".
1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).If the turning torque is l
ess than the specified range:
Decrease the side bearing adjusting shim thickness.
If the turning torque is gr eater than the specification:
Increase the side bearing adjusting shim thickness.
