LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS004CM
Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
CAUTION:
Adjust laser beam aiming at a horizontal place as far as 12 m (39 ft) forward the vehicle can be
seen.
Adjust laser beam aiming 5 seconds after starting engine.
Never view ICC sensor integrated unit body window directly during laser beam aiming adjustment.
Follow the CONSULT-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).
Never ride on vehicle during laser beam aiming adjustment.
Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS004CN
Adjust the tire pressure to the specified value.
See that there is no load in the vehicle.
Coolant, engine oil filled up to correct level and full fuel tank.
Shift the gear into “P” position and release the parking brake.
Clean the ICC sensor integrated unit with a soft cloth.
Remove the front bumper grille. Refer to EI-13, "Removal and
Installation of Front Bumper Grille" .
Outline of Adjustment ProcedureNKS004CO
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II. (Turn manually the screw for up-down position
adjustment. ICC sensor integrated unit automatically adjust the right-left position.)
Setting the ICC Target BoardNKS004CP
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale at 28 mm (1.10 in) below the center.

6. Touch “LASER BEAM ADJUST”.
7. Touch “START”.
CAUTION:
If the adjustment screen does not appear on the CONSULT-
II screen in 10 seconds. After touching “LASER BEAM
ADJUST” screen, the following causes may be considered:
Target is not set accurately.
There is not enough space beside the target.
The range of laser beam aiming exceeds for improper
installation position.
–Deformation of vehicle body.
–Deformation of unit.
–Deformation of bracket.
The area is not suitable for the adjustment work.
ICC sensor integrated unit is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the up-down direction adjusting
screw until “U/D CORRECT” value is set in the range of
4.
CAUTION:
Turn the screw slowly. The value change on display is
slower than actual movement of the ICC sensor integrated
unit. Wait for 2 seconds every time the screw is turned half
a rotation.
NOTE:
Turning the screw clockwise to laser beam is downward and
counterclockwise to laser beam is upward.
9. When “U/D CORRECT” value indicates
4, confirm that the margin of value remains within 4 at least for
2 seconds with no equipment or hand touching the ICC sensor integrated unit.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions NCS001JE
Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.
When removing the transmission from a vehicle, do not use the
companion flange section at the rear end of the transmission as
a support point. (VK45DE models only)
Always use the specified brand of ATF. Refer to MA-12, "Fluids
and Lubricants" .
Use lint-free paper not cloth rags during work.
After replacing the ATF, dispose of the waste oil using the meth-
ods prescribed by law, ordinance, etc.
Before proceeding with disassembly, thoroughly clean the out-
side of the transmission. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign mat-
ter.
Disassembly should be done in a clean work area.
Use lint-free paper or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation
of the transmission.
Place disassembled parts in order for easier and proper assem-
bly.
All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
Gaskets, seals and O-rings should be replaced any time the
transmission is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

SHIFT CONTROL SYSTEM
Revision: 2006 January2006 M35/M45
Checking of A/T PositionNCS001QO
1. Place selector lever in “P” position, and turn ignition switch ON (engine stop).
2. Make sure that selector lever can be shifted to other than “P” position when brake pedal is depressed.
Also make sure that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the A/T body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Make sure that A/T is locked completely in “P” position.
10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination
meter.
Shift selector lever to “+” and “-” sides, and check that set shift position changes.
