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 inoperative, which cou ld increase the ris k of personal inju ry 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, in cluding incorrect removal a nd installation of the SRS, can lead to per-

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 equipme nt on any circuit related to the SRS unle ss instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors .

DESCRIPTION

DESCRIPTION PFP:00000 Outline AKS00C8B

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 preview function).

VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE

Vehicle-to-vehicle distance control mode, the driver can maintain the same speed as other vehicles without the constant need to adjust the set speed as you would with a normal cruise control system. The system is in tended to enhance the op eration of the vehicle when f ollowing the vehicle trave ling 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 dista nce. 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) cr uise 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 brake pre-pressure be fore driver depress the brake peda l and improves brake response by reducing its free play. Refer to Owner's Manual for BRAKE ASSIST (WITH PREVIEW FUNCTION) operating instructions.

Transmit operating signal to ICC unit when touching brake pedal. ICC unit cancels cruise system at driver's brake operation.

CAN Communication AKS00C8E

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 transmit s/receives data but selectively reads required data on ly.

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

ACS002L3

The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, us ed 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 s tage front ai r 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 inoperative, which could inc rease the risk of pe rsonal 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 maintenanc e, including incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional activ ation of the system. For removal of Spiral Cable and A ir Bag Module, see the SRS section.

● Do not use ele ctrical test equipmen t on any c ircuit rela ted to the SRS unless instructed to in th is

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Precautions for On Board Diagnostic (OBD) System of A/T and Engine ACS002L5

The ECM has an on boa rd diagnos tic system. It wil l light up the m alfunction indicator la mp (MIL) to warn th e driver of a malfunction causing emission deterioration.

CAUTION:

● Be sure to turn the ignition switc h OFF and di sconnec t the battery ca ble from the negative term i-

nal before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. Will cause the MIL to light up.

● Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will

cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.)

● Be sure to route and secure the harnesses properly after work. Interference of the harness with a

bracket, etc. May cause the MIL to light up due to a short circuit.

● Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube

may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.

● Be sure to e rase the unnece ssary m alfunction inform ation (repairs co mpleted) from the TCM and

ECM before returning the vehicle to the custom er.

PRECAUTIONS

Precautions ACS002L6

● Before connecting or disconne cting the A/T assembly har-

ness connector, turn ignition switch OFF and disconnect the battery cable from the nega tive terminal. Because battery voltage is applied to TCM even if ignition switch is turned OFF.

SEF289H

● After performing each TROUBLE DIAGNOSIS, perform

“DTC (Diagnostic Trouble Code) Confirmation Procedure”. If the repair is completed the DTC should n ot be displayed in the “DTC Confirmation Procedure”.

SEF217U

● Always use the specified brand of ATF. Refer to MA-12, "Fluids and Lubricants" .

● Use paper rags not cloth r ags during wor k.

● After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.

● Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to

prevent the internal parts from becoming contaminated by dirt or other foreign matte r.

● Disassembly should be done in a clean work area.

● Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere

with the operation of the trans m is si on .

● Place disassembled parts in order for easier and proper assembl y.

● All parts should be carefully cleansed with a general purpose, non-flammable solv ent before inspection or

reassembly.

● Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.

● It is very important to perform functional tests whenever they are indicated.

● The valve bo dy contains precision part s a nd r equi r es ex tre me ca re w hen parts are r em ov ed an d s er v ic ed.

Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs and small parts from becoming scattered or lost.

● Properly installed valves , sleeves, plugs, etc. will slide along bores in valve body under their own weight.

● Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings

and seals, or hold bearings and washers in place during assembly. Do not use grease.

● Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

● After overhaul, refill the transmission with new ATF.

● When the A/T drai n plug is remo ved, on ly some o f the fl uid is d rained. Old A/T fluid w ill remain in torq ue

converter and ATF cooling system. Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer to AT-12, "

Changing A/T Fluid" , AT-13, "Checking A/T Fluid" .

PRECAUTIONS

Service Notice or Precautions ACS002L7

ATF COOLER SERVICE

If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solven t and co mpress ed air a fter repair. For A/T fluid cooler cl eani ng proc edu re, refer to AT -15, "

Fluid Cooler Cleaning" . For radiator replacement, refer to CO-14, "RADIATOR" (for VQ35DE), CO-41, "RADIATOR" (for VK45DE).

A/T

OBD-II SELF-DIAGNOSIS

● A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through

the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table on AT- 9 4, "

SELF-DIAGNOSTIC RESULT MODE" for the in dicator used to d isplay each self-dia gnostic

result.

● The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-

ories.

Always perform the procedure on AT-40, "

HOW TO ERASE DTC" to complete the repair and avoid

unnecessary blinking of the MIL.

For details of OBD-II, refer to EC-54, "

ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VQ35DE) or EC-745,

"ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VK45DE).

● Certain systems and components, especial ly those related to O BD, may use th e new style slid e-

locking type harness connector. For description and how to disconnect, refer to PG-74, "

HAR-

NESS CONNECTOR" .

Wiring Diagrams and Trouble Diagnosis ACS002L8

When you read wiring diagrams, refer to the following:

● GI-15, "How to Read Wiring Diagrams".

● PG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.

When you perform trouble diagnosis, refer to the foll owing:

● GI-11, "How to Follow Trouble Diagnoses".

● GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident".

A/T FLUID

A/T Fluid Cooler Cleaning ACS004Q5

Whenever an automatic transmission is replaced, the A/T fluid cooler mounted in the radiator must be inspected and cleaned. Metal debris and fri ct ion ma teri al, i f pres ent, can beco me trapp ed i n the A/T fl uid c oole r. This debris ca n co ntaminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case, malfunction of the newly serviced A/T may result. Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler through the cooler outlet in order to flush out any built up debris.

A/T FLUID COOLER CLEANING PROCEDURE

1. Position an oi l pan under the automatic transmission's inlet and outlet cooler hoses.

2. Identify the inlet and outlet fluid cooler hoses.

3. Disconnect the fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.

NOTE:

Replace the cooler hoses if rubber material from the hose remains on the tube fitting.

4. Allow any A/T fluid that remains in the cooler hoses to drain into the oil pan.

5. Insert the extension adapter hose of a can of Transmission Cooler Cleaner (Nissan P/N 99 9MP-AM00 6) into the coole r outlet hose.

CAUTION:

● Wear safety glasses and rubber gloves when spraying

the Transmission Cooler Cleaner.

● Spray cooler cleaner only with ad equ ate venti lation.

● Avoid contact with eyes and skin.

● Do not breat h vapors or spray mist.

6. Hold the hose and can as high as possible and spray Transmission Cooler Cleaner in a continuous stream into the cooler outlet hose until fluid flows out of the cooler inlet hose for 5 seconds.

7. Insert the tip of an air gun into the end of the cooler outlet hose.

8. Wrap a shop rag around th e air gun tip and of the cooler outle t hose.

9. Blow compressed air regulated to 5 - 9 kg/cm

(70 - 130 psi) through the cooler outlet hose for 10 seconds to forc e out any remaining fluid.

10. Repeat steps 5 through 9 three additional ti mes.

11. Pos ition an oil pan under the banjo bolts that conne ct the fluid cooler steel lines to the transmission.

12. Remove the banjo bolts.

13. Flush each steel line from the cooler side back toward the transmission by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.

14. Blow compressed air regulated to 5 - 9 kg/cm

(70 - 130 psi) through each steel line from the c oo ler s id e

back toward the transmission for 10 seconds to force out any remaining fluid.

15. Ensure all debris is removed from the steel cooler lines.

16. Ensure all debris is removed from the banjo bolts and fittings .

17. Perform AT-16, "
