PRECAUTION
PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012431235
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 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 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 Power Generation Voltage Variable Control SystemINFOID:0000000012431236
CAUTION:
For model with power generation voltage variable control system, the battery current sensor that is
installed to the battery cable at the negative te rminal measures the charging/discharging current of
the battery, and performs various controls. If the electrical component or the ground wire is connected
directly to the battery terminal, the current othe r than that being measured with the battery current
sensor is charging to or discharging from the battery. This cond ition causes the malfunction of the
control, and then the battery discharge may occur. Do not connect the electrical component or the
ground wire directly to the battery terminal.

COMPONENT PARTS
Component Description
INFOID:0000000012431240
No. Component part Description
1 IPDM E/R The IPDM E/R converts the received power generation com-
mand value into a pulse width modulated (PWM) command sig-
nal and sends it to the IC regulator.
2ECM The battery current sensor detects the charging/discharging
current of the battery. The ECM judges the battery condition
based on this signal.
The ECM judges whether to request more output via the power
generation voltage variable control according to the battery
condition.
When performing the power generation voltage variable con-
trol, the ECM calculates the target power generation voltage
according to the battery condition and sends the calculated val-
ue as the power generation command value to the IPDM E/R.
3 Battery current sensor The battery current sensor is located on the negative battery
cable terminal. The battery current sensor detects the charg-
ing/discharging current of the battery and sends a voltage sig-
nal to the ECM according to the current value detected.
4 Generator (IC regulator) The IC regulator controls the power generation voltage by the
target power generation voltage based on the received PWM
command signal.
When there is no PWM command signal, the generator per-
forms the normal power generation according to the character-
istic of the IC regulator.
5 Combination meter (charge warning lamp) The IC regulator warning function activates to illuminate the
charge warning lamp if any of the following symptoms occur
while generator is operating:
• Excessive voltage is produced.
• No voltage is produced.
