Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001516585
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 SR and SB section 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 SR 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 har-
ness connectors.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001337832
NOTE:
 This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
 Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
 Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

DIAGNOSIS AND REPAIR WORKFLOW
1. GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2
2. CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data (Print them out with CONSULT-III.)
- Erase DTC.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3
Symptom is described, DTC is not displayed>>GO TO 4
Symptom is not described, DTC is displayed>>GO TO 5
3. CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5
4. CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR ” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6
5. PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to XX-XX, "*****"
and determine trouble diagnosis order.
NOTE:
 Freeze frame data is useful if the DTC is not detected.
 Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This
simplified check procedure is an effective alternative though DTC cannot be detected during this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirma-
tion Procedure.

< FUNCTION DIAGNOSIS >[WITH I-KEY, WITHOUT SUPER LOCK]
DOOR LOCK FUNCTION
If the following conditions are not satisfied, door lock and unlock operation is not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock and unlock
function is in the range of approximately 80 cm (31.50 in) surround-
ing the driver and passenger door handles (1) and the back door
(hatchback) or trunk (sedan) request switch. However, this operating
range depends on the ambient conditions.
DOOR LOCK AND UNLOCK CONTROL
When the Intelligent Key detects that door request switch is pressed, it starts corresponding with outside key
antenna (door of request switch pressed side). Then, the Intelligent Key is checked to be near the door.
If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and trans-
mits the key ID signal to the Intelligent Key unit. Intelligent Key unit receives the key ID signal and compares it
with the registered key ID. Intelligent Key unit sends the door lock and unlock signal to BCM via CAN commu-
nication.
ANTI-HIJACK MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock driver door. Pressing UNLOCK button
on Intelligent Key a second time within 5 seconds from the first time will unlock all doors and back door (hatch-
back) can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener
switch.
CONVENIENCE MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock all doors and back door (hatchback)
can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener switch.
NOTE:
Anti-hijack mode can be set to ON or OFF with CONSULT-III. Once OFF, the convenience mode will be active.
For setting information with CONSULT-III, refer to DLK-53, "
CONSULT-III Function (INTELLIGENT KEY)". For
setting information without CONSULT-III, refer to Owner's Manual.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001396507
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex 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 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.
