LASER BEAM AIMING ADJUSTMENT
LASER BEAM AIMING ADJUSTMENT
OutlineINFOID:0000000001328812
Adjust the laser beam aiming every time the ICC sensor 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 un it body window directly during laser beam aiming adjustment.
 Follow the CONSULT-III when adju sting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-III).
 Never ride on vehicle during l aser beam aiming adjustment.
 Idle and turn headlamps OFF duri ng laser beam aiming adjustment.
PreparationINFOID:0000000001328813
 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 with a soft cloth.
Outline of Adjustment ProcedureINFOID:0000000001328814
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSUL T-III. (Turn manually the screw for up-down position
adjustment. ICC sensor automatically adjust the right-left position.)
Setting the ICC Target BoardINFOID:0000000001328815
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 the center.

2. Adjust the height of the target board stand so that the point of the triangle aims the cent er of the ICC sensor.
ADJUSTING THE RIGHT-LEFT POSITION OF THE TARGET
1. Attach a scale [at least 350 mm (14 in) or longer] or stick as
shown in the figure.
2. Suspend a thread with weight on the tip of the thread to 310 mm (12.2 in) left side of the target board from the center of the target
board on top.
SETTING THE TARGET
1. Suspend a thread with weight on tip to splice the cent er of the front and rear bumpers. Then, mark the
center point on the ground as each weight points.
2. Link the front and rear bumpers center points ma rked on the ground, and mark a point 5 m (16.4 ft) ahead
of the sensor, on the extended line of the previous lin k line of the bumper center points. Then, adjust the
position of the target board so that the weight come on the top of the marked point [5 m (16.4 ft) ahead of
the sensor] and face to the vehicle.
3. Adjust the position of the target board so that the extended line that links the center of the rear window glass (the center of the
rear window defogger pattern) and the center of the windshield
(the setting part of the room mirror) align with the weight sus-
pended from the board.
4. Remove the thread suspended to the left side of board and sus- pend a thread with weight on tip on the center of the target
board. Then mark the point of weight on the ground.

REFRIGERANT LINES
 O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-
pressure pipe 3).
 Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor
can be located in the same position.
 When recharging refrigerant, check for leaks.
Removal and Installation of Expansion ValveINFOID:0000000001328230
REMOVAL
1. Remove evaporator. Refer to ATC-137, "Removal and Installation of Evaporator".
2. Remove mounting bolts, and then remove expansion valve. CAUTION:
Cap or wrap the joint of evaporator with suitable material
such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
 Replace O-rings of evaporator with new ones, and then apply compressor oil to it when installing it.
 O-rings are different from low-pressure pipe 1 (h igh-pressure pipe 2) and low-pressure pipe 2 (high-
pressure pipe 3).
 When recharging refrigerant, check for leaks.
Checking of Refrigerant LeaksINFOID:0000000001328231
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage ma y indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
If dye is observed, c onfirm the leak with an electrical leak detector. It is possible a prior leak was repaired and
not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electric al leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leak area will improve the
chances of finding a leak.
Checking System for Leaks Using the Fluore scent Leak DetectorINFOID:0000000001328232
1. Check A/C system for leaks using the UV lamp and safety goggles (SST: J-42220) in a low sunlight area
(area without windows preferable). Illuminate all co mponents, fittings and lines. The dye will appear as a
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (SST: J-43872) to prevent future
misdiagnosis. Low-pressure pipe 1 bracket mounting bolt
