Power Generation Variable Voltage Control System Inspection

EKS00FTR

CAUTION:

●

For this model, the battery current sensor that is installed to the negative battery cable measures
the charging/discharging current of the battery and performs various engine controls. If an electri-
cal component is connected directly to the negative battery terminal, the current flowing through
that component will not be measured by the battery current sensor. This condition may cause a
malfunction of the engine control system and battery discharge may occur. Do not connect an
electrical component or ground wire directly to the battery terminal.

●

When performing this inspection, always use the charged battery that completed the battery
inspection. When the charging rate of the battery is low, the response speed of the voltage change
will become slow. This is a cause of an incorrect inspection.

INSPECTION PROCEDURE

1. 

CHECK SELF-DIAGNOSIS OF ECM

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
in self-diagnosis depending on control unit which carries out CAN communication.

Perform ECM self-diagnosis with CONSULT-II.

2. 

CHECK POWER GENERATION VARIABLE VOLTAGE CONTROL SYSTEM OPERATION

1.

Connect CONSULT-II and CONSULT-II CONVERTER and start the engine.

2.

Put selector lever in “P” or “N” position and turn all electric loads including A/C OFF.

3.

Select “ALT DUTY” at “ACTIVE TEST” of “ENGINE”, and then
check the value of “BATTERY VOLT” monitor when “ALTERNA-
TOR DUTY” is set to 40 %.

4.

Check the value of “BATTERY VOLT” when “ALTERNATOR
DUTY” is set to 80%.

OK or NG

OK

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

EIS007UJ

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 and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

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
harness connectors.

Precautions for Work

EIS007UK

●

When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.

●

When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-
nent with a shop cloth or vinyl tape to protect it.

●

Protect the removed parts with a shop cloth and keep them.

●

Replace a deformed or damaged clip.

●

If a part is specified as a non-reusable part, always replace it with new one.

●

Be sure to tighten bolts and nuts securely to the specified torque.

●

After re-installation is completed, be sure to check that each part works normally.

●

Follow the steps below to clean components.

–

Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the
fouled area.
Then rub with a soft and dry cloth.

–

Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub
with a soft and dry cloth.

●

Do not use organic solvent such as thinner, benzene, alcohol, or gasoline.

●

For genuine leather seats, use a genuine leather seat cleaner.
