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 [commercial service tool: (J-41413-OBD)] to the EVAP
service port may cause a leak.
1.EVAP LEAK CHECK
With CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” in “WOR K SUPPORT” mode of “ENGINE” using CONSULT.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until t he pressure indicator reaches the middle of the bar
graph.
6. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
7. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
Without CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009976114
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
On Board Diagnosti c (OBD) System of Engine and CVTINFOID:0000000009462476
The ECM has an on board diagnostic system. It will illuminate the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
• Always to turn the ignition swit ch OFF and disconnect the negative battery cable before any repair
or inspection work. The open/short circuit of re lated switches, sensors, solenoid valves, etc. will
cause the MIL to illuminate.
• Always to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to illuminate due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For descrip tion and how to disconnect, refer to PG-65, "Description"
.
• Always route and secure the harnesses properly afte r work. The interference of the harness with a
bracket, etc. may cause the MIL to illu minate due to the short circuit.
• Always to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to illuminate due to the malfuncti on of the EVAP system or fuel injection system,
etc.
• Always to erase the unnecessary malfunction informati on (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOST
IC (OBD) SYSTEM
Diagnosis DescriptionINFOID:0000000009462531
This system is an on board diagnostic system that re cords exhaust emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A ma lfunction is indicated by the malfunction indicator
lamp (MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diag-
nostic tool (GST: Generic Scan Tool).
GST (Generic Scan Tool)INFOID:0000000009462532
When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the
control unit equipped in the vehicle and then enable va rious kinds of diagnostic tests. Refer to EC-590, "Diag-
nosis Description".
NOTE:
Service $0A is not applied for regions where it is not mandated.

BASIC INSPECTION
Work ProcedureINFOID:0000000009462550
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for scheduled maintenance.
2. Open engine hood and check the following:
- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leakage
- Air cleaner clogging
- Gasket
3. Check that electrical or mechanical loads are not applied.
- Head lamp switch is OFF.
- Air conditioner switch is OFF.
- Rear window defogger switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature indicator points to the middle of gauge.
Check that engine stays below 1,000 rpm.
5. Run engine at approximately 2,000 rpm for approximately 2 min- utes under no load.
6. Check that no DTC is displayed with CONSULT or GST.
Are any DTCs detected?
YES >> GO TO 2.
NO >> GO TO 3.
2.REPAIR OR REPLACE
Repair or replace components as necessary according to corresponding Diagnostic Procedure.
>> GO TO 3
3.CHECK TARGET IDLE SPEED
1. Run engine at approximately 2,000 rpm for approximately 2 minutes under no load.
