EVAP LEAK CHECK
EVAP LEAK CHECK
InspectionINFOID:0000000006267340
CAUTION:
 Do not use compressed air or a high pressure pump.
 Do not exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in EVAP system.
NOTE:
 Do not start engine.
 Improper installation of EVAP service port adapter (com mercial service tool) to the EVAP service port may
cause a leak.
WITH CONSULT-III
1. To locate the EVAP leak, install EVAP service port adapter (com- mercial service tool) and pressure pump to EVAP service port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT” mode with CONSULT-III.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until the pressure indicator reaches the middle of the bar graph.
6. Remove EVAP service port adapter (commercial service tool) and hose with pressure pump.
7. Locate the leak using a leak detector (commercial service tool). Refer to EC-45, "
EVAPORATIVE EMISSION SYSTEM : System
Diagram".
WITHOUT CONSULT-III
1. To locate the EVAP leak, install EVAP service port adapter (com-
mercial service tool) and pressure pump to EVAP service port.
2. Apply battery voltage between the terminals of EVAP canister vent control valve to ma ke a closed EVAP system.
3. To locate the leak, deliver positive pressure to the EVAP system until pressure gauge points reach 1.38 to 2.76 kPa (0.014 to
0.028 kg/cm
2, 0.2 to 0.4 psi).
4. Remove EVAP service port adapter (commercial service tool) and hose with pressure pump.

APPLICATION ITEM
WORK SUPPORT
*: Adjusts the steering angle sensor neutral position on ABS actuator and electrical unit (control unit) side. Refer to
BRC-64, "Work Pro-
cedure".
DATA MONITOR
*: The swivel angle "0°" (feedback value) of the swivel position sensor signal may differ from the swivel angle "0 °" of the swivel motor
(AFS control unit command value). This causes that the swivel motor initializes the value based on the step number from the sto pper.

Diagnostic mode Description
Ecu Identification Allows confirmation of AFS control unit part number.
Self Diagnostic Result Displays the diagnosis results judged by AFS control unit.
Work support Sets each sensor.
Data monitor Indicates AFS control unit input data in real time.

WHEEL ALIGNMENT
InspectionINFOID:0000000006225640
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
 Tires for improper air pressure and wear
 Road wheels for runout: Refer to WT-64, "
Inspection".
 Wheel bearing axial end play: Refer to FA X - 7 , "
Inspection" (2WD), FAX-16, "Inspection" (4WD).
 Lower link and upper link ball joint axial end play: Refer to FSU-15, "
Inspection" and FSU-18, "Inspection".
 Shock absorber operation.
 Each mounting part of axle and suspension for looseness and deformation
 Lower link for cracks, deformation and other damage
 Vehicle height (posture)
GENERAL INFORMATION AND RECOMMENDATIONS
 A four-wheel thrust alignment should be performed.
- This type of alignment is recomm ended for any NISSAN/INFINITI vehicle.
- The four-wheel “thrust” process helps ensure that t he vehicle is properly aligned and the steering wheel is
centered.
- The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
- The rack should be checked to ensure that it is level.
 Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
 When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Never use these indicators.
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
- This may result in an ERROR.
 Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Never use this “Rolling Compensation” method.
- Use the “Jacking Compensation Method”. After installi ng the alignment targets or head units, raise the vehi-
cle and rotate the wheels 1/2 turn both ways.
- See Instructions in the alignment machine you're using for more information on this.

CAMBER, CASTER
1. Adjust with the front/rear side adjusting bolts (1) on the lower link
(2).
2. See the following table for the amount of cam bolt scale move- ment and the variation of camber and caster.
CAUTION:
Align the adjusting bolt cutout with the stamp of lower link
bracket.
