PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR B AG” and “SEAT
BELT PRE-TENSIONER”
AKS004EO
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, use d along
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
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 Manual.
WARNING:
● To avoid rendering the SRS ino perative, w hich could inc rease the ris k 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, inc luding incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional activation of the system . For removal of Spiral Cable and A ir
Bag Module, see the SRS section.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

A/T Overdrive Control During Cruise Control Driving
When the vehicle speed is approximately 3 km/h (2 MPH) below set speed, a signal is sent
● from ASCD control unit terminal 10
● to TCM (transmission control module) through combination meter.
When this occurs, the TCM (transmission control module ) cancels overdrive.
After vehicle speed is approximately 1 km/h (0.6 MPH) above set speed, overdrive is react ivated.
ASCD Shifting Control
During ASCD cruise, ASCD control unit controls A/T shifting to avoid uncomfortable shifting.
This is used to control the signals below.
● Throttle position sensor fro m ECM
● A/T shift solenoid valve A
Coast Operation
When the SET/COAST switch is depressed during cruise control driving, ASCD actuator returns the throttle

Accel Operation
When the RESUME/ACCEL switch is depressed, power is supplied
● from ASCD control unit terminal 11
● to ASCD steering switch terminal 2.
If the RESUME/ACCEL switch is depressed during cruise control driving, ASCD actuator pulls the throttle
cable to increa se th e v eh ic le sp ee d u nti l the switch is releas ed or v eh ic le speed reaches the ma x im um sp ee d
controlled by the system. ASCD will then keep the new set speed.

Cancel Operation
When any of following conditions exist, cruise operation will be canceled.
● CANCEL switch is depressed. (Power supply to ASCD control unit terminal 11)
● Brake peda l is depressed. (Power supply to ASC D control unit ter minal 23 from stop lamp switch)
● Brake pedal is depressed or A/T selector lever is shifted to P or N position. (Power supply to ASCD con-
trol unit terminal 8 is inte rrupted.)
If MAIN (CRUISE) switch is turned to OFF during ASCD activation, all ASCD operations will be canceled and
vehicle speed memory will be erased.
Resume Operation
When the RESUME /ACCEL switch is depressed after cancel operation other th an when depressing MAIN
(CRUISE) switch is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must meet following conditions.
● Brake ped al is released.
● A/T selector lever is in other than P and N position.
● Vehicle speed is greater than 40 km/h (25 MPH) and less than 144 km/h (89 MPH).
ASCD PUMP OPERATION
The ASCD pump consists of a vacuum motor, an air valve and a release valve. When the ASCD activates,
power is supplied
● from ASCD control unit terminal 12
● to ASCD pump terminal 1.
Ground is supplied to vacuum motor, air valve and release valve from ASCD control unit depending on the
operated condition as shown in the below table.
The pump is connected to ASCD actuator by vacuum hose. When the ASCD pump is activated, the ASCD
pump vacuum affects the diaphragm of ASCD actu ator to control throttle cable.

PRECAUTIONS PFP:00001
Precautions 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 sea t belt , helps t o redu ce th e r isk or s everi ty of injury to th e driv er an d front passenge r for c ertain
types of collisi on . Thi s s ys te m in cludes seat belt swi tch inp uts an d du al stag e front air bag modules. T he 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 ne ce ss ary t o se rvi ce th e sy stem saf e ly is i nclu de d in th e SR S and SB se ct i on of th is Ser vic e Manual.
WARNING:
● To avoid rendering the SRS inoperativ e, which cou ld increase the risk of persona l 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, incl uding incorrect removal and installation of the SRS, can lead to pe r-
sonal injury caused by unintentional activation of the system. For rem oval of Spiral Cable and Ai r
Bag Module, see the SRS section.
● Do not use electrical test equipment on any circ uit 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 .
AKS004EP
Precautions for ICC System Service AKS002PP
● Do not look straight into the laser beam discharger when adjusting laser beam aiming.
● Turn the ON/OFF switch OFF in conditions similar to driving, suchlike Free rollers or a chassis dynamom-
eter.
● Do not use the ICC sensor removing from vehicle, disassemble, or remodel the sensor.
● Erase DTCs when replacing parts of ICC system, then check the operation of ICC system after adjusting
laser beam ai ming if necessary.

DESCRIPTION PFP:00000
Outline AKS00AO0
The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle
ahead accordi ng to that vehicle's speed, or at the set speed, if the road ahead is clear.
The ICC function has two cruise control modes and brake assist (with pr eview function).
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Vehicle-to-vehicle distance control mode, the same speed as other vehic les can be maintained without the
constant need to adjust the operating speed as with a normal cruise control system.
The system is intended to enhance the operation of the vehicle when following another vehicle in the same
lane and direction.
If the dist an ce sen sor de tec t s a slow e r mo vi ng ve hi cl e a head , th e syste m w il l r edu ce sp ee d s o th at the ve hi cle
ahead can be followed at the selected distance.
The system automatically controls the throttle and applies the brakes (up to 25% of vehicle braking power) if
necessary.
The detection range of the sensor is approximately 390 ft (120 m) ahead.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Conventional (fixed speed) cruise control mode is cruising at preset speeds.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
BRAKE ASSIST (WITH PREVIEW FUNCTION)
When the force applie d to brake p edal exc eeds a certain lev el, the Brak e Assist is activated and gene rates a
greater braking force than that of a conventional brake booster even with light pedal force.
When the Preview Fun ct ion identifies the nee d to app ly the sud de n b r ak e by se ns in g th e vehicle ahead in the
same lane and the distance and relative speed from it , it applies the brak e pre-pressure before driver depress
the brake peda l and improves brake response by reducing its free pl ay.
Refer to Owner's Manual for BRAKE ASSIST (WITH PREVIEW FUNCTION) operating instructions.

CAN Communication AKS002PV
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electric control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during opera tion (not independent). In CA N communication, cont rol units are connected with 2
communicatio n lines ( CAN H lin e, CAN L li ne) all owi ng a high ra te of in forma tion tr ans missi on wit h less wir ing.
Each control unit transmits/r eceives data but selectively reads required data only.
