L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000003860523
The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis ProcedureINFOID:0000000003860524
1.CHECK “L” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “L” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “L” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect alternator connector.
2. Apply ground to alternator harness connector terminal.
3. Check condition of the charge warning lamp with the ignition switch in the ON position.
Does it illuminate?
YES >> “L” terminal circuit is normal. Refer to CHG-2, "Work Flow".
NO >> GO TO 3.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the battery cable from the negative terminal.
2. Disconnect the combination meter connector.
3. Check continuity between alternator harness connector and combination meter harness connector.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair the harness or connector.
4.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check continuity between combination meter harness connector and fuse block.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair the harness.
5.CHECK POWER SUPPLY CIRCUIT
1. Connect the battery cable to the negative terminal.

DescriptionINFOID:0000000003860527
The output voltage of the alternator is controlled by the IC voltage regulator at the “S” terminal detecting the
input voltage.
The “S” terminal circuit detects the battery voltage to adjust the alternator output voltage with the IC voltage
regulator.
Diagnosis ProcedureINFOID:0000000003860528
1.CHECK “S” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “S” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “S” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “S” TERMINAL CIRCUIT
Check voltage between alternator harness connector and ground.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003860531
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 Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003801896
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
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”.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Liquid GasketINFOID:0000000003793163
REMOVAL OF LIQUID GASKET SEALING
 After removing mounting nuts and bolts, separate the mating sur-
f a c e u s i n g t h e s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ( J37228)] (A) and
remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
 Tap (B) the seal cutter [SST: KV10111100 (J37228)] to insert it, and
then slide (C) it by tapping on the side as shown in the figure.
 In areas where seal cutter [SST: KV10111100 (J37228)] is difficult
to use, use a plastic hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper (A), remove old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
 Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

PRECAUTIONS
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
 If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
 As for the bolt holes (B), normally apply liquid gasket inside
the holes. Occasionally, it should be applied outside the holes.
Check to read the text of service manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Never retighten after mounting bolts and nuts the installation.
 After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

InspectionINFOID:0000000003793166
LEVEL
 Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
 Adjust the engine coolant level as necessary.
LEAKAGE
 To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator cap
tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
 If anything is found, repair or replace damaged parts.
DrainingINFOID:0000000003793167
WARNING:
 To avoid being scalded, never change engine coolant when the engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
1. Remove engine under cover.
2. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-110, "
Disassembly and Assembly".
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
