2. CHECK OPERATION OF POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
1. Connect CONSULT-II and start the engine.
2. The selector lever is in “P” or “N” position and all of the electric
loads and A/C, etc. are turned OFF.
3. Select “ALTERNATOR DUTY” at “ACTIVE TEST” of “ENGINE”,
and then check the value of “BATTERY VOLT” monitor when
DUTY value of “ALTERNATOR DUTY” is set to 40.0 %.
4. Check the value of “BATTERY VOLT” monitor when DUTY value
of “ALTERNATOR DUTY” is set to 80.0%.
OK or NG
OK >> INSPECTION END
NG >> GO TO 3. (The charging condition of the battery should
be normal.)
3. CHECK IPDM E/R (CONSULT-II)
Perform IPDM E/R self-diagnosis with CONSULT-II. Refer to PG-20, "
CONSULT-II Function (IPDM E/R)" .

No malfunction detected>> GO TO 4.
Malfunction detected>> Check applicable parts, and repair or replace corresponding parts.
4. CHECK HARNESS BETWEEN ALTERNATOR AND IPDM E/R
1. Turn ignition switch OFF.
2. Disconnect alternator connector and IPDM E/R connector.
3. Check continuity between alternator harness connector (A) and
IPDM E/R harness connector (B).
4. Check continuity between alternator harness connector (A) and
ground.
OK or NG
OK >> Replace IPDM E/R.
NG >> Repair harness or connector between IPDM E/R and alternator. “BATTERY VOLT”

Alternator Pulley Inspection
Perform the following.

Make sure that alternator pulley does not rattle.

Make sure that alternator pulley nut is tight.
Installation
Installation is the reverse order of removal.
CAUTION:
Be sure to tighten “B” terminal nut carefully.

Install alternator, and check tension of belt. Refer to EM-16, "Checking Drive Belts" .

For this model, the power generation voltage variable control system that controls the power generation
voltage of the alternator has been adopted. Therefore, the power generation voltage variable control sys-
tem operation inspection should be performed after replacing the alternator, and then make sure that the
system operates normally. Refer to SC-29, "
Power Generation Voltage Variable Control System Operation

INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30×50 mm (1.18×1.97 in)
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15×25 mm (0.59×0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW (TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit. Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingNIS0028X
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by
applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate
wiring harness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you
will not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

AUTOMATIC DRIVE POSITIONER
Revision: 2007 April2007 M35/M45
System DescriptionNIS0025R

The system automatically moves the driver seat, steering and door mirror position by the driver seat con-
trol unit and the automatic drive positioner control unit. The driver seat control unit corresponds with the
automatic drive positioner control unit via UART communication. The driver seat control unit can store the
optimum driving positions (driver seat, steering and door mirror position) for 2 people. If the driver
changes, one-touch operation allows changing to the other driving position.

The driver seat, steering and door mirror position are adjusted automatically to the proper positions for the
driver in different ways: MEMORY OPERATION, EXITING OPERATION, ENTRY OPERATION and
INTELLIGENT KEY INTERLOCK OPERATION.
MANUAL OPERATION
The driving position (seat, steering and door mirror position) can be adjusted with the power seat switch, ADP
steering switch and door mirror control switch.
NOTE:
The door mirrors can be manually operated with the ignition switch in either ACC or ON.
MEMORY OPERATION
The driver seat control unit can store the optimum driving positions (seat, steering and door mirror position) for
2 people. If the front seat position is changed, one-touch (pressing desired memory switch for more than 0.5
second) operation allows changing to the other driving position.
Operation procedure
1. Turn ignition switch ON.
2. Press desired memory switch for 0.5 second. (Indicator LED illuminates.)
3. Driver seat, steering and door mirror will move to the memorized position.
(Indicator LED blinks during adjustment, then illuminates for 5 seconds.)
Operation Condition
If the following conditions are not satisfied, memory switch operation is not performed.

Ignition switch is in ON position.

Driver side power seat switch, ADP steering switch and door mirror control switch are not operated.

Seat memory switch and set switch are not operated.

Output malfunction is not detected.

CAN and UART communications are normal.

A/T selector lever position is in P position.

Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF, vehicle speed is higher than
7 km/H. (4 MPH).]

Input voltage from tilt sensor and telescopic sensor are normal.
NOTE:
The memory operation operates following order.
Function Description
Manual operationThe driving position (seat, steering and door mirror position) can be adjusted with
the power seat switch ADP steering switch or door mirror control switch.
Auto-
matic
operationMemory operation The seat, steering and door mirror move to the stored driving position by pushing
seat memory switch (1 or 2).
Entry/
Exiting
functionExiting operation At exit, the seat moves backward and the steering wheel moves upward.
Entry operationAt entry, the seat and steering wheel returns from exiting position to the previous
driving position before the exiting operation.
Intelligent Key interlock operationPerform memory operation, exiting operation and entry operation by pressing Intel-
ligent Key unlock button.

SE-14
AUTOMATIC DRIVE POSITIONER
Revision: 2007 April2007 M35/M45
EXITING OPERATION
When exiting, when the condition is satisfied, the seat is moved backward 40 mm (1.57 in) from normal sitting
position and the steering is moved to the most upper position and front position.
The seat slide amount and the steering operation at entry/exit operation can be changed by set switch, CON-
SULT-II and display (located in the instrument panel). Refer to SE-16, "
SETTING CHANGE FUNCTION" .

CAN communications are normal.

Initialization has been done. Refer to SE-16, "INITIALIZATION PROCEDURE" .
ENTRY OPERATION
When the seat is in the exiting position when either condition (1 or 2) is satisfied, the seat returns from exiting
position to the previous driving position.
