L TERMINAL CIRCUIT (SHORT)
DescriptionINFOID:0000000009460665
The terminal “L” circuit controls the charge warning
lamp. The charge warning lamp turns ON when the igni-
tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,
the charge warning lamp turns off. If the charge warn ing lamp illuminates with the engine running, a malfunc-
tion is indicated.

Regarding Wiring Diagram information, refer to CHG-12, "Wiring Diagram".
1.CHECK “L” TERMINAL CIRCUIT (SHORT)
1. Turn ignition switch OFF.
2. Disconnect generator connector.
3. Turn ignition switch ON.
Does charge warning lamp illuminate?
YES >> GO TO 2.
NO >> Refer to CHG-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or CHG-20, "Work Flow (With-
out EXP-800 NI or GR8-1200 NI)".
2.CHECK HARNESS CONTINUI TY (SHORT CIRCUIT)
1. Turn ignition switch OFF.
2. Disconnect the battery cabl e from the negative terminal.
3. Disconnect combination meter connector.
4. Check continuity between the comb ination meter harness connector and ground.

S TERMINAL CIRCUIT
S TERMINAL CIRCUIT
DescriptionINFOID:0000000009460667
The output voltage of the generator is controlled by the IC regulator at terminal “S” detecting the input voltage
from battery.
The “S” terminal circuit detects the battery voltage to adjust the generator output voltage with the IC voltage
regulator.
Diagnosis ProcedureINFOID:0000000009460668
Regarding Wiring Diagram information. Refer to CHG-12, "Wiring Diagram".
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 repa ir by performing complete Charging system test
using EXP-800 NI or GR8-1200 NI (if available). Refer to the applicable Instruction Manual for
proper testing procedures.
2.CHECK “S” TERMINAL CIRCUIT
Check voltage between generator harness connector and ground.
Is the inspection result normal?
YES >> Refer to CHG-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or CHG-20, "Work Flow (With-
out EXP-800 NI or GR8-1200 NI)".
NO >> Check harness for open between generator and fuse.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951689
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 t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Precaution for Liquid GasketINFOID:0000000009460384
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"
.
