AUTOMATIC DRIVE POSITIONER
Revision: 2006 January2006 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.

CAN Communication System DescriptionNIS0025S
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS0008O
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.
WAR NING :
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 SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceNHS0008P
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
Diagnosis sensor unit must always be installed with their arrow marks “” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.
The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and column after removal of steering gear.
Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
down.
Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Always replace instrument panel pad following front passenger air bag deployment.
Occupant Classification System PrecautionNHS0008Q
Replace occupant classification system control unit and passenger front seat cushion as an assembly.
Refer to SE-165, "
Passenger's Seat Components" .

3. Remove the screws then remove the steering switch.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Fix the air bag module harness (shown as A in the figure) to
the harness fixing hook (shown as B in the figure).
Be careful not to damage the harness while installing.
Tighten the special bolts after exactly adjusting the centers of fixing holes on the air bag module
side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged and the
module is not installed securely.
After the work is completed, make sure no system malfunction is detected by air bag warning
lamp.
In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis func-
tion and delete the memory by CONSOULT–II.
In case that malunction is still detected after the above operation, peform self-diagnosis to repair
malfunctions. Refer to SRS-19, "
SRS Operation Check" .
