LASER BEAM AIMING ADJUSTMENT
Revision: August 20072004 QX56

The area is not suitable for the adjustment work.

ICC sensor is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the vertical adjusting screw until
“U/D CORRECT” value is set in the range of ±4.
CAUTION:
Turn the screw slowly. The value on the CONSULT-II is
slower than the actual movement of the ICC sensor. Wait 2
seconds between each adjustment.
NOTE:
Turning the screw clockwise raises the ICC sensor and counter-
clockwise lowers the ICC sensor.
9. When “U/D CORRECT” value indicates ±4, confirm that the value remains within ±4 for at least 2 seconds
while nothing is touching the ICC sensor.
When “COMPLETED THE VERTICAL AIMING OF LASER
BEAM” appears on screen, touch “END”.
CAUTION:
Be sure that the margin of “U/D CORRECT” is within ±4
when the ICC sensor unit is untouched.
10. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER
BEAM AIMING” is on screen and wait while the horizontal
adjustment is made automatically. (maximum: 10 seconds).

REMOVAL
1. Remove the select lever knob.
2. Remove console finisher.

Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
3. Remove center console.

Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
4. Disconnect selector control cable.
5. Disconnect A/T device harness connector.
6. Remove control device assembly.
INSTALLATION
Installation is in reverse order of removal.
NOTE:


: Vehicle front
Apply adhesive, Cemedyne 3000 or equivalent, to thread of select
lever knob before installation. Rotate knob clockwise through com-
plete thread range (A) at low torque. When knob rotation is finished
through complete thread range, rotation torque will sunddenly
increase. Continue knob rotation in incomplete thread range (B), not
more than 360°, until knob rotational position is as shown.

After installation is completed, adjust and check A/T position.
Adjustment of A/T PositionECS0090O
1. Loosen nut of control cable.
2. Place PNP switch and selector lever in “P” position.
3. After pushing the control cable in the direction shown with a
force of 9.8 N·m (1kg-m, 2.2 lb-ft), release it. This is in the natu-
ral state, tighten control cable nut to specifications.
Checking of A/T PositionECS0090P
1. Place selector lever in “P” position, and turn ignition switch ON
(engine stop).
2. Make sure selector lever can be shifted to other than “P” posi-
tion when brake pedal is depressed. Also make sure 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 transmission body.
5. The method of operating the lever to individual positions correctly should be as shown.
6. Confirm the back-up lamps illuminate only when lever is placed in the “R” position. Confirm the back-up
lamps does not illuminate when selector lever is pushed against “R” position in the “P” or “N” position.

INSTALLATION
Installation of the remaining components is in the reverse order of
the removal, while paying attention to the following work.

If removed install drive plate.
–Align dowel pin of crankshaft rear end with pin holes of each
parts to install.
–Install drive plate, reinforcement plate and pilot converter as
shown.
–Face chamfered or rounded edge side to crankshaft.
CAUTION:

When replacing an engine or transmission you must make
sure the dowels are installed correctly during re-assembly.

Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.

When installing transmission to the engine, attach the bolts in
accordance with the following standard.
*: No.2 bolt also secures air breather vent.
–Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed from the front of the engine.

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
transmission rotates freely without binding.

After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to AT-13,
"Checking A/T Fluid" , AT-234, "Checking of A/T Position" , AT-234, "Adjustment of A/T Position" .

SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. If an improper
connection is attempted, discharging and contamination may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
lubricants have been used with the scale. If the scale controls refrig-
erant flow electronically, the hose fitting must be 1/2”-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Wiring Diagrams and Trouble DiagnosisEJS002BO
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams"

PG-4, "POWER SUPPLY ROUTING CIRCUIT"
When you perform trouble diagnosis, refer to the following:
