11. Remove alternator mounting bolt (upper).

12. Completely loosen lower alternator mounting bolt (lower), and pull it out until the bolt head is in contact

with the side member. And then, remove the alternator by pulling it forward.
NOTE:
The alternator can be removed together with the bolts by pulling it forward and using the alternator bracket
bolt hole cutout.

13. Remove alternator upward from the vehicle.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:

• Temporarily tighten the alternator bolts in order from the upper to the lower, and then tighten them in

order from the upper to the lower.
For the alternator, the front side (pulley side) surface is the reference surface. Fit the reference sur-
face to the alternator mounting part, and then tighten the bolts.

• Be careful to tighten “B” terminal nut to the specified torque.
• Install alternator, and check tension of belt. Refer to

EM-373, "Checking"

• For this model (with battery current sensor models), the energy management system that controls

the power generation voltage of the alternator has been adopted. Therefore, the power generation
voltage variable control system operation inspection should be performed after replacing the alter-
nator, and then make sure that the system operates normally. Refer to

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000010675473

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 AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric 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 3 minutes before performing any service.

Precautions for Removing Battery Terminal

INFOID:0000000010675474

• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key

or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.

• When disconnecting the 12V battery terminal, turn off the ACC

power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

HOW TO DISCONNECT 12V BATTERY TERMINAL

Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.

INSTRUCTION 1

Open the hood.

PRECAUTIONS

CHG-37

< PRECAUTION >

[TYPE 2]

Turn key switch to the OFF position with the driver side door opened.

Get out of the vehicle and close the driver side door.

Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)

Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.

Open the driver side door.

Open the hood.

Close the driver side door.

Wait at least 3 minutes.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

SYSTEM DESCRIPTION

• IPDM E/R sends alternator voltage request signal to ECM via CAN communication.
• ECM transmits alternator voltage request signal to alternator via LIN communication.
• Control module inside alternator controls the power generation voltage based on the received alternator volt-

age request signal.

• Alternator includes a self-diagnosis function and transmits the diagnosis result to ECM via LIN communica-

tion when detecting any malfunction.

• Charge warning lamp turns ON when any of the following symptom occurs while ignition switch is ON:
- Excessive voltage is produced.
- No voltage is produced.
- High voltage is detected from battery positive terminal.
- The communication between alternator and ECM is not available.
