Check that there is the un-match display in any camera.
Is the un-match display visible?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK THAT AROUND VIEW MONITOR CONTROL UNIT IS REPLACED
Check that the around view monitor control unit is replaced.
Is the around view monitor control unit replaced?
YES >> GO TO 3.
NO >> GO TO 5.
3.RELEASE UN-MATCH DISPLAY (PERFORM ONLY WHEN THE AROUND VIEW MONITOR CONTROL
UNIT IS REPLACED)
1. Select “Camera Cont.” of Confirmation/ Adjust ment mode, and then set to “Calibrating Camera Image”
mode.
2. Press the “ENTER” switch of the multifunction switch on each screen of “Rear Camera”, “Front Camera”, “Dr-Side Camera”\
,
“Pass-Side Camera”.
CAUTION:
 Do never operate the center dial and up/down/left/right
switches. Only press the “ENTER” switch.
 Never perform “Initialize Camera Image Calibration”.
3. Display the around view monitor screen, and check that there is
no malfunction such as a difference between each camera
image.
Is there a malfunction?
YES >> Calibration end
NO >> GO TO 1.
4.PERFORM SIMPLIFIED CONFIRMATION/ADJUSTM ENT BY “FINE TUNING OF BIRDS-EYE VIEW”
1. Put target line 1 on the ground beside each axle using packing tape, etc.
2. Put target lines 2 equal to the vehicle total length + approximately 1.0 m (39.3 in) from the vehicle side
(right and left) at approximately 30 cm (11.8 in) away from the vehicle (make the line as parallel with the
vehicle as possible)

 Install the brake pedal assembly and hydraulic booster assembly mounting nuts, and tighten it to the speci- fied torque. Refer to BR-28, "
Exploded View".
 Perform adjustment after installation. Refer to BR-21, "
Inspection and Adjustment".
NOTE:
The clevis pin may be inserted in either direction.
Inspection and AdjustmentINFOID:0000000006222474
INSPECTION AFTER REMOVAL
 Check for the following items and replace the brake pedal assembly if necessary.
- Check the brake pedal upper rivet (made by aluminum) (B) for deformation.
- Check the brake pedal for bend, damage, and cracks on the welded parts.
- Check the lapping length (A) of sub-bracket (1) and slide plate (2).
 Check clevis pin and plastic stopper (A) for damage and deforma-
tion. If any is found, replace clevis pin.
ADJUSTMENT AFTER INSTALLATION
Perform the brake pedal adjustment after installing the brake pedal assembly. Refer to BR-7, "Inspection and
Adjustment".

HYDRAULIC BOOSTER ASSEMBLY
 Apply new brake fluid to grommet of between reservoir tank and grommet and ABS actuator and electric unit
(control unit).
Inspection and AdjustmentINFOID:0000000006222486
ADJUSTMENT BEFORE INSTALLATION
Input Rod Length adjustment
1. Loosen the lock nut (1) and adjust the input rod (2) to the speci-
fied length (A).
2. Tighten the lock nut to the specified torque.
INSPECTION AFTER INSTALLATION
Operation Check
1. Turn the ignition switch OFF.
2. Depress the brake pedal 20 times or more. NOTE:
The pressure loss in the accumulator results in a large brake pedal stroke. In addition to this, the brake
pedal depression becomes lighter in initial stage.
3. Check that the fluid level in the reservoir tank is MAX line.
4. Position the selector lever in P range to release the parking brake.
5. Turn the ignition switch ON to check the time between motor activation and motor stop.
6. After the motor is stopped, check that the ABS warn ing lamp and the VDC warning lamp in the combina-
tion meter are OFF when the engine is started.
7. Stop the engine (ignition switch OFF).
8. Turn the ignition switch ON and depress the brake pedal 4 to 5 times to check the time between motor activation and motor stop.
9. Turn the ignition switch OFF. Turn the ignition swit ch ON again. Check that the VDC warning lamp turns
ON when the brake pedal is depressed 15 to 20 times.
10. Check that the VDC warning lamp turns ON when the brake pedal is depressed 15 to 20 times after the lapse of 120 seconds or more after the ignition switch is turned ON again.
11. Perform the self-diagnosis for “ABS” with CONSULT- III and erase all the stored self-diagnosis results.
Function Check
1. Turn the ignition switch OFF.
2. Depress the brake pedal 20 times or more.
NOTE:
The pressure loss in the accumulator results in a large brake pedal stroke. In addition to this, the brake
pedal depression becomes lighter in initial stage.
3. Turn the ignition switch ON with the brake pedal depr essed to check that the clearance between the brake
pedal and the dash lower panel decreases. A : Refer to
BR-47, "
Brake Booster".
