INSPECTION AND ADJUSTMENT
LASER BEAM AIMING ADJUSTMENT : Setting up the ICC Target Board
INFOID:0000000003776927
CAUTION:
Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment.
For details, refer to T echnical Service Bulletin.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown.
2. Adjust the height of the target stand so that the point of the trian-
gle aims above the center of the ICC sensor.
ADJUSTING THE POSITION OF THE TARGET BOARD STRING
1. Attach a scale or straightedge (at least 350 mm [14 in] orlonger).
2. Suspend a string with a weight on the end 218 mm (8.6 in) to the left side of the target board center.
POSITIONING THE TARGET
1. Suspend a string with weights on each end over the cent erline of the vehicle. The string should lay over
the center of the front and bac k bumpers. Mark these centerpoi nts on the ground at each weight.

2. Connect the two center points using a string. Extend the string an additional 5 m (16 ft) beyond the front centerpoint and mark
the floor. Position the target board weight on this mark.
3. Relocate the suspended string from the left side of the target board to the center of the target board. Mark this point on the ground.
4. Pivot the target board on its center mark 20 ° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift will produce a 20 ° movement.
5. Remove any items in the shaded space shown in the figure.
NOTE:
In case the background space shown in the illustration is not available, or if the background is light col-
ored, place a 400 mm (15.75 in) long frosted black board or black cloth to both sides of the target board.
LASER BEAM AIMING ADJUST MENT : Sensor AdjustmentINFOID:0000000003776928
CAUTION:
Never view ICC sensor unit bod y window directly during laser beam aiming adjustment.
NOTE:
Complete all necessary steps for laser beam adjustm ent until the CONSULT-III indicates "COMPLETED". If
the procedure does not complete , the ICC system is inoperable.
1.SET CONSULT-III TO THE LASER BEAM AIMING ADJUSTMENT MODE
1. Connect CONSULT-III and select "Work Support" of "ICC".
2. Select "LASER BEAM ADJUST".
3. Touch "START".

HOOD
CLEARANCE AND SURFACE HEIGHT ADJUSTMENT
1. Remove the front grille. Refer to
EXT-17, "Removal and Installation".
2. Remove the hood lock assembly and adjust the height by rotating the bumper rubber until the hood clear- ance of hood and fender becomes 1 mm (0.04 in) lower than fitting standard dimension.
3. Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and striker for looseness, and tighten the lock mounting bolt to the specified torque.
4. Adjust the clearance and surface height of hood and fender according to \
the fitting standard dimension by rotating right and left bumper rubbers.
CAUTION:
Adjust right/left gap between hood and each part to the following specification.
5. Install the front grille. Refer to EXT-17, "
Removal and Installation".
HOOD LOCK ADJUSTMENT
1. Remove the front grille. Refer to EXT-17, "Removal and Installation".
2. Move the hood lock to the left or right so that striker center is vertically aligned with hood lock center (when viewed from vehicle front).
3. Make sure the secondary latch is properly engaged with the sec- ondary striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or by pressing it lightly approx.
3 kg (29 N, 7lb).
CAUTION:
Do not drop the hood from 300 mm (11.81 in) height or
higher.
4. After adjusting hood lock, tighten the lock bolts.
5. Install the front grille. Refer to EXT-17, "
Removal and Installa-
tion".
Removal and Installation of Hood AssemblyINFOID:0000000003775852
1. Support the hood striker with proper material to prevent it from falling.
WARNING:
Body injury may occur if no supporting rod is holding the
hood open when removing the damper stay.
2. Remove the hinge nuts from the hood to remove the hood assembly.
CAUTION:
Operate with two workers, because of its heavy weight.
Installation is in the reverse order of removal. Hood and headlamp (B–B) : 2.0 mm or less

HOOD
4. Install the primary and secondary cables securely to the hood
lock.
5. Install the hood lock and the secondary hood lock release assemblies.
6. Check the hood lock adjustment and hood opener operation. Refer to DLK-229, "
Fitting Adjustment".
7. Install the remaing componets in the reverse order of removal.
Hood Lock Control InspectionINFOID:0000000003775854
CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Remove the front grille. Refer to EXT-17, "
Removal and Installation".
2. Make sure the secondary latch is properly engaged with the sec- ondary striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height.
3. While operating the hood opener, carefully make sure the front end of the hood is raised by approx. 20 mm (0.79 in). Also make
sure the hood opener returns to the original position.
4. Check the hood lock lubrication condition. If necessary, apply “body grease” to the points shown in the figure.
5. Install the front grille. Refer to EXT-17, "
Removal and Installa-
tion".
Hood Stay DisposalINFOID:0000000005877751
1. Fix hood stay (1) using a vise (C).
2. Using hacksaw (A) slowly make 2 holes in the hood stay, in numerical order as shown in the figure.
CAUTION:
• When cutting a hole on hood stay, always cover a hack-saw using a shop cloth (B) to avoid scattering metal frag-
ments or oil.
• Wear eye protection (safety glasses).
• Wear gloves.
