DTC DETECTION LOGIC
NOTE:
• If DTC P1217 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first pe rform the trouble diagnosis for DTC P0607. Refer
to EC-884, "DTC Logic"
.
If the cooling fan or another component in the coo ling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be su re to replace the coolant. Refer to CO-35, "System Inspection"
.
Also, replace the engine oil. Refer to MA-27, "ENGINE OIL : Changing Engine Oil"
.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-12, "FOR USA AND CANADA : Engine Cool-
ant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-892, "Component Function Check"
.
NOTE:
Use component function check to check the overall functi on of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-893, "Diagnosis Procedure"
.
Component Function CheckINFOID:0000000009462750
1.PERFORM COMPONENT FUNCTION CHECK-I
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.

Check the coolant level in the reservoir tank and radiator.
Allow engine to cool befo re checking coolant level.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?
YES >> Proceed to EC-893, "Diagnosis Procedure".
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK-II
Confirm whether customer filled the coolant or not.
Did customer fill the coolant?
YES >> Proceed to EC-893, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM COMPONENT FUNCTION CHECK-III
With CONSULT
1. Turn ignition switch ON.
2. Perform “FAN DUTY CONTROL” in “ACTI VE TEST” mode of “ENGINE” using CONSULT.
3. Check that cooling fan speed varies according to the percentage.
Without CONSULT
1. Activate IPDM E/R auto active test and check cooling fan motors operation. Refer to PCS-8, "Diagnosis
Description".
2. Check that cooling fan operates.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-893, "Diagnosis Procedure"
.
Diagnosis ProcedureINFOID:0000000009462751
1.CHECK COOLING FAN OPERATION
With CONSULT
1. Turn ignition switch ON.
2. Perform “COOLING FAN” in “ACTIVE TE ST” mode of “ENGINE” using CONSULT.
3. Check that cooling fans-1 and -2 operate at each speed (LOW/MID/HI).
Without CONSULT
1. Activate IPDM E/R auto active test and check cooling fan motors operation. Refer to PCS-8, "Diagnosis
Description".
2. Check that cooling fans-1 and -2 operate at each speed (Low/Middle/High).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Proceed to EC-953, "Diagnosis Procedure"
.
2.CHECK COOLING SYSTEM FOR LEAK-I
Check cooling system for leak. Refer to CO-35, "System Inspection"
.
Is leakage detected?
YES >> GO TO 3.
NO >> GO TO 4.
3.CHECK COOLING SYSTEM FOR LEAK-II
Check the following for leak.
• Hose (Refer to CO-35, "System Inspection"
.)
• Radiator (Refer to CO-35, "System Inspection"
.)
• Water pump (Refer to CO-35, "System Inspection"
.)

Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951675
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.
Precaution for Draining CoolantINFOID:0000000009460453
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460454
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before any removal or disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460455
• When instructed to use special service tools, use the s pecified tools. Always be careful to work safely, avoid
forceful operations.
• Use maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or equivalent , if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, follow the specifications.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460456
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
