Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003941991
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, 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 NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000003795058
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003845516
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

MALFUNCTION INDICATOR (MI)
Description
The MI is located on the instrument panel.
1. The MI will illuminate when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
If the MI does not illuminate, check MI circuit. Refer to EC-346,
"Component Function Check".
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
On Board Diagnostic System Function
The on board diagnostic system has the following three functions.
Diagnostic Test Mode I — Bulb Check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check MI circuit. Refer to EC-
346, "Component Function Check".
Diagnostic Test Mode I — Malfunction Warning

WARNINGWhen a malfunction is detected twice in two consecutive
driving cycles (two trip detection logic), the MI will illuminate
to inform the driver that a malfunction has been detected.
The following malfunctions will illuminate or blink the MI in
the 1st trip.
 Misfire (Possible three way catalyst damage)

RESULTSThis function allows DTCs and 1st trip DTCs to be read.

EC-108
< FUNCTION DIAGNOSIS >[VQ25DE, VQ35DE]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
This DTC number is clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
Diagnostic Test Mode II — Self-diagnostic Results
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are dis-
played, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
codes can be identified by using the CONSULT-III or GST. A DTC will be used as an example for how to read
a code.
A particular trouble code can be identified by the number of four-digit numeral flashes as per the following.
The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-sec-
onds) - OFF (0.6-seconds) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-seconds OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-389, "
DTCIndex")
How to Switch Diagnostic Test Mode
NOTE:
It is better to count the time accurately with a clock.

ON When the malfunction is detected.
OFF No malfunction.

Diagnosis ProcedureINFOID:0000000003856513
1.CHECK OIL PRESSURE WARNING LAMP
1. Start engine.
2. Check oil pressure warning lamp and confirm it is not illumi-
nated.
Is oil pressure warming lamp illuminated?
YES >> Go to LU-7, "Inspection".
NO >> GO TO 2.
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Refer to EC-138, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace malfunctioning intake valve timing control solenoid valve.
3.CHECK CRANKSHAFT POSITION SENSOR (POS)
Refer to EC-221, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace crankshaft position sensor (POS).
4.CHECK CAMSHAFT POSITION SENSOR (PHASE)
Refer to EC-224, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace malfunctioning camshaft position sensor (PHASE).
5.CHECK CAMSHAFT (INTAKE)
Check the following.
ENG SPEED 1,200 - 3,175 rpm (A constant rotation is maintained.)
COOLAN TEMP/S More than 70°C (158°F)
Selector lever 1st or 2nd position

DTC DETECTION LOGIC
NOTE:
If DTC P1217 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-135, "
DTC Logic".
If DTC P1217 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer
to EC-242, "
DTC Logic".
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, always replace the coolant. Refer to CO-8, "
Draining". Also, replace
the engine oil. Refer to LU-8, "
Draining".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Always use
coolant with the proper mixture ratio. Refer to MA-12, "
Engine Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-250, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-251, "
Diagnosis Procedure".

WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
