PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
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 AIRBAG” and “SEAT BELT” of this
Service Manual.
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 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 the “SRS AIRBAG”.
• 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.

AUTOMATIC DRIVE POSITIONER SYSTEM : System Description
INFOID:0000000001693618
OUTLINE
The system automatically moves the driver seat, steering column and door mirror position by the driver seat
control unit and the automatic drive positioner control unit. The driver seat control unit corresponds with the
automatic drive positioner control unit by UART communication.
Function Description
Manual function
Seat synchronization function
Memory function
Power walk-in function
Intelligent Key interlock function
NOTE:
The lumbar support system and the side support system are controlled independently with no link to the automatic drive positioner system.
The driving position (seat, steeri ng column an d door mirror po sition) can be adjusted by using the
power seat switch, tilt & telescopic switch or door mirror remote control switch.
The positions of the steering column and door mirror are adjusted to the proper position automatically while linking with manual operation [seat sliding, seat lifting (rear) or seat reclining].
The seat, steering column and outside mirror move to the stored driving position by pressing seat
memory switch (1 or 2).
The seat is made to advance when the seat back of driver seat is folded down and press the walkin switch. The seat is made to retreat to former position when the seat back of driv er seat is folded
up and press the walk-in switch.
Perform memory operation, exiting operation and entry operation by Intelligent Key unlock operation or driver side door request switch unlock operation.

The driving position (seat, steering column and door mirror position) can be adjusted manually with power seat
switch, tilt & telescopic switch and door mirror remote control switch.
OPERATION PROCEDURE
1. Operate power seat switch, tilt & telescopic switch or door mirror remote control switch.
NOTE:
The door mirrors can be operated manually when ignition switch is in either ACC or ON position. The ignition switch signal (ACC/ON) is transmitted from BCM to the driver seat control unit via CAN communication and from the driver seat control unit to the automatic drive positioner control unit via UART
communication.
2. The driver seat, steering column or door mirror operates according to the operation of each switch.

< FUNCTION DIAGNOSIS >
The steering column position and door mirror position is adjusted to the position automatically according to the
direction and distance of seat movement when performing the manual operation of sliding, reclining or lifting
(rear). This function saves adjusting the mirror and steering column when adjusting the seat.
NOTE:
Seat synchronization function can change the setting by operating the set switch.
For the system setting procedure. Refer to ADP-12, "
OPERATION PROCEDURE
1. Turn ignition switch ON.
2. Adjust seat position [sliding, reclining, lifting (rear)].
3. The steering and outside mirror is adjusted automatically.
NOTE:
• The seat synchronization function will not operate if seat adjusting value is more than limit value.
Item Limit value
Seat sliding 76 mm
Seat reclining 9.1 degrees
Seat lifter (rear) 20 mm
• The seat synchronization function will not operate if the steering column or door mirror moves to the operating end while this function is operating. Perform memory function or drive the vehicle at vehicle speed of 7
km/h or more once to activate this function again.
• If the seat position is uncomfortable after the adjustment, seat position can be adjusted easily by memory
operation.

The driver seat control unit judges the direction and distance of
seat movement according to the signal input from each seat sensor during manual operation.
Driver seat control unit requests the operation to position according to the direction and distance of seat movement to the automatic drive positioner control unit via UART communication . The
automatic drive positioner control unit operates each motor.
Driver seat control unit stops the operation of each motor when the

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description INFOID:0000000001693649
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, 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, CAN-L) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
