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 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 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 could inc rease 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, including incorrec t removal and installation of the SRS , can lead to per-

sonal injury caused by unintentional activation of th e sy ste m. 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 PFP:00001

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

ACS004YD

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 sys tem includes seat belt switch inputs and dual s tage 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 necessary to service the system safely is included in the SRS and SB section of this Service Manual.

WARNING:

● To avoid ren dering the SRS ino perative, whi ch 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, including incorrect rem oval and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional activ atio n of the system. For re mo val of Spiral Cable and Air Bag Module, see the SRS section.

● Do not use electrical test equipm ent on a ny circuit re lated to the SRS un less in structed to in this

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 ACS000G0

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 switch “OFF ” and disconnect the negative batte ry cable 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 erase the u nnecessar y malfunc tion i nformation (repairs complete d) from th e TCM and

ECM before returning the vehicle to the custom er.

PRECAUTIONS

Precautions for TCM, A/T Assembly and Control Va lve Assembly Replacement

ACS000G1

CAUTION:

● Check data (Unit ID) in TCM with data monitor of CONSULT-II before replacing A/T a ssem bly (c on -

trol valve assembly).

● Check if new data (Unit ID) are entered correctly after replacing A/T assembly (control valve

assembly) and erasing data in TCM.

● When replacing A/T assembly, control valve assembly or TCM, refer to the pattern table below and erase

the EEPROM in the TCM if necessary.

EEPROM ERASING PATTERNS

A/T assembly or control

valve assembly

Replaced Replaced Not required

Not replaced Replaced Not required

Replaced Not replaced Require d

METHOD FOR ERASING THE EEPROM IN THE TCM

1. Connect CONSULT-II to data link connector.

2. Turn ignition sw itch ON. Confir m that CONSULT-II turn “ON”.

3. Move selector lever in “R” pos ition.

4. Touch “START” on CONSULT-II.

5. Select “SELF-DIAG RESULTS” mode for “A/T” with CONSULT-II.

6. Fully press the accelerator pedal (8/8 throttle), and hold it in the fully open position. (This will set the closed throttle position signal to “OFF”.)

7. Touch “ERASE” on CONSULT-II, and then touch “YES”.

8. Wait 3 seconds and then release the accelerator pedal.

9. Turn ignition sw itch OFF.

TCM Erasing EEPROM in TCM Remarks

Not required because the EEPROM in the TCM is in the default state.

Required because data has been written in the EEPROM in the TCM and because the TCM cannot write data from the ROM assembly in the transmission.

METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSMISSION

In the following proced ure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the TCM.

1. With the EEPROM in the TCM erased.

2. Move selector lever in “P” p osition.

3. Turn ignition switch ON.

CHECK METHOD

● Normal: About 2 seconds after the ignition switch ON, the A/T CHECK indicator lamp lights up for 2

seconds.

● Abnormal: Even after the ignition switch ON, the A/T CHECK indicator lamp does not light up after 2 sec-

onds or illuminates immediately.

Cope for Abnormal

● Replace the cont rol valve assembly.

● Replace the TCM.

AT-8

Page 22

PRECAUTIONS

Precautions ACS000G2

● Before connecting or disconnecting the TCM harness con-

nector, turn ignition switch “OFF” and d isconnect ne gative battery cable. Because battery voltage is applied to TCM even if ignition switch is turned “OFF”.

● When connecting or disconnec ting pin connectors into or

from TCM, take care not to dama ge pin terminals (bend or break). Make sure that there are not any ben ds or breaks on TCM pin terminal, when connecting pin connectors.

● Before replacing TCM, perform TCM input/output signal

inspection and make sure wheth er TCM functions properly or not. AT-89, "

TCM INSPECTION TABLE".

SEF289H

SEF291H

MEF040DA

● After performing each TROUBLE DIAGNOSIS, perform

“DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”. If the repair is completed the DTC sh ould not be displaye d in the “DTC CONFIRMATION PROCEDURE”.

SEF217U

● Always use the speci fied brand of A/T fluid. Refer to MA-9, "Fluids and Lubricants" .

● Use paper rags not cloth rags during work.

● After replacing the A/T fluid, dispose of the waste oil using th e methods prescribed by law, ordinance, etc.

● Before proceeding with disassemb ly, thoroughly clean the o utside of the transaxle. It is important t o pre-

vent the internal parts from becoming contaminated by dirt or other foreign matter.

● Disassembly should be done in a clean work area.

AT-9

Page 23

PRECAUTIONS

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

with the operation of the transax le .

● Place disassemb led parts in order for easier and proper assembly.

● All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or

reassembly.

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

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

● The va l ve body co ntains prec is io n p a r t s a nd req ui res ex tr e me car e wh en parts are r em oved an d s er v iced .

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 bore s in va lv e bo dy unde r thei r ow n weig ht.

● 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 t ransaxle with new ATF.

● When the A/T drain plug is rem oved, only s ome of t he fluid is drai ned. Old A/T flu id will re main i n torque

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-13, "

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

A/T Fluid Cooler Cleaning ACS006CU

Whenever an au to ma tic tra ns m is si on is repai red, overhauled, or rep la ce d, the A/T fluid cooler mo un ted 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.

Line Pressure Control

● When an input torque signal equivalent to the engine drive force is sent from the ECM to the TCM, the

ACS0008G

TCM controls the line press ure solenoid.

● This line pressure solenoid controls the press ure regulator va lve as the signa l pressure and ad justs the

pressure of the o perating oil dischar ged from the oil pump to the line pressur e most appropriate to t he driving state.

PCIA0007E

LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC PATTERN

● The TCM has stored in memory a n umb er of patterns for t he o ptimu m li ne p ressu re ch arac terist ic fo r the

driving state.

● In order to obtain the most appropriate l ine pressure chara cteristic to meet th e current driving state, t he

TCM controls the line pressure solenoid cur rent valve and thus controls t he line pressure.

Normal Control

Each clutch is adjusted to the necessary pressure to match the engine drive force.

Back-up Control (Engine Brake)

When the select operation is executed during driving and the transmission is shifted down, the line pressure is set according to the vehicle speed.

During Shift Change

The necessary a nd adequate line pressure for sh ift change is set. For this reason, line pressure pattern setting corresponds to input torque and gearshift selection. Also, line pressure characteristic is according to engine sp ee d, during engine brake oper ati on .

At Low Fluid Temperature

When the A/T fluid temperature drops below the prescribed temperature, in order to speed up the action of each friction element, the line pressure is set higher than the no rma l lin e pre ss ure char ac te ris tic .

● In the l oc k- u p rel e as ed st at e, the t orqu e c on ve rte r cl utch co nt rol va lv e is set in to the unl o cke d s t at e b y t he

torque converter clutch solenoid and the lock-up apply pressure is drained. In this way, the torque converter clutch piston is not coupled.

Lock-up Applied

● In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the

torque converter clutch solenoid and lock -up apply pressure is genera ted. In this way, the torque converter clutch piston is pressed and coupled.

SMOOTH LOCK-UP CONTROL

When shifting f rom the lock -up releas ed st at e to the lock- up ap plied st ate, the cur rent outp ut to the tor que converter clutch sole noid is controlled with the TCM. In this w ay, when shifting to the lock-up applied s tate, the torque converter clutch is temporarily set to the half-clutched state to reduce the shock.

Half-clutched State

● The current output from the TCM to the torque converter clutch solenoid is varied to steadily increase the

torque converter clutch solenoid pressure. In this way, the lock-up apply pressure gradually rises and while the torque convert er clutch pisto n is put into half-clutc hed status, the to rque conv erter clutch piston ope rating pres sure is incr eased and the coupling is completed smoothly.

Slip Lock-up Control

● In the slip region, the to rque conv erter cl utch s oleno id c urrent is con troll ed w ith t he TCM to p ut it into the

half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed. This raises the fuel e fficiency for 4 th and 5th ge ar at both low s peed and when the acc elerator has a low degree of opening.

Engine Brake Control

● The forward one-way clutch transmits the driv e force from th e engine to the rear whe els. But the rev erse

ACS0008J

drive from the rear wheels is not transmitted to the engine because the one-way clutch is idling. Therefore, the low coast brake solenoi d is operated to prevent the forward one-w ay clutch from idling and the engine brake is operated in the same manner as conventi onally.

● The operation of the low coast brake solenoid switches the low coast brake switching valve and controls

the coupling and releasing of the low coast brake. The low coast brake reducing valve controls the low coast brake coupling force.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

PFP:00028

Introduction ACS0008L

The A/T system has two self-diagnostic systems. The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in the ECM memory but not the TCM memory. The second is the TCM original self-diagn os is indic ated by the A/T CHECK indic at or la mp . The malfunction is stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For detail, refer to AT-93, "

SELF-DIAGNOSTIC RESULT MODE" .

OBD-II Function for A/T System ACS0008M

The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the ECM when a mal function occurs in the corre sponding OBD-related part. The other function is to ind icate a diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel. Sensors, switches and solenoid valves are used as sensing eleme nts. The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation to A/T system parts.

One or Two Trip Detection Logic of OBD-II ACS0008N

ONE TRIP DETECTION LOGIC

If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in the ECM memory as a DTC. The TCM is not provided wit h such a memory function.

TWO TRIP DETECTION LOGIC

When a malfuncti on is sensed during the fi rst test drive, it is stored in the ECM memory as a 1st trip DT C (diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — First Trip If the same malf unction as that experien ced during the first test drive is sense d during the second te st drive, the MIL will illuminate. — Second Trip The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed during vehicle operation.

OBD-II Diagnostic Trouble Code (DTC) ACS004ZB

HOW TO READ DTC AND 1ST TRIP DTC

DTC and 1st trip DTC can be read by the following methods. ( with CONSULT-II or GST) CONSUL T-II or GST (Generic Scan Tool) Examples: P0705, P0720 etc.

These DTC are prescribed by SAE J2012. (CONSULT-II also di splays the mal functioning component or system.)

● 1st trip DTC No. is the same as DTC No.

● Output of the diagnostic trouble code indicates that the indic ated circuit has a malfu nction. How-

ever, in case of the Mode II and GST , they do not indicate whether the malfunction is still occurring or occurred in the past and returned to normal. CONSULT-II can identify them as shown below, therefore, CONSULT-II (if available) is recommended.

A sample of CONSULT-II display for DTC and 1st trip DTC is shown on the next page. DTC or 1st trip D TC of a malf unction is displaye d in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CONSULT-II. Time data indicates how many times the vehicl e w a s dri ve n after the last detection of a DTC.

SAT014K

AT-38

ON BOARD DIAGNOSTIC (OBD) SYSTEM

If the DTC is being detected currently, the time data will be “0”.

If a 1st trip DTC is stored in the ECM, the time data will be “1t”.

SAT015K

SAT016K

Freeze Frame Data and 1st Trip Freeze Frame Data

The ECM has a me mory function, whic h stores the driving c ondition such as fuel s ystem status, calcul ated load value, engin e coolant temperature, short te rm fuel trim, long term fuel trim, engin e speed and vehicle speed at the moment the ECM detects a malfunction. Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data, and the data, s tored to gether with t he DTC data, a re call ed freez e fram e data an d disp layed on CO NSULT-II or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For detail, refer to EC-105, "

CONSULT-II Function" .

Only one set of freeze frame data (either 1st trip freeze frame data of freeze frame data) can be stored in the ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority for 1st trip freeze fr ame data and it is update d each time a different 1st trip DTC is det ected. However, once freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no longer stored. R eme mber, only one set of free ze fra me da ta can be stored in the ECM . The ECM has th e following pri orities to update the data.

Priority Items

1 2 Except the above items (Includes A/T relate d item s)

3 1st trip freeze frame d ata

Freeze frame data

Misfire — DTC: P0300 - P0306 Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175

Both 1st trip freeze frame data and freeze fr ame data (along w ith the DTC) are cleared when the ECM memory is erased.

HOW TO ERASE DTC

The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as described followi ng .

● If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.

● When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode

selector on t he ECM.

The following emi ssion-related diagnostic inf ormation is cleared from the ECM m emory when erasing DTC related to OBD-II. For details, refer to EC-47, "

Fail-Safe ACS0008R

The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is a malfunction in a main electronic control input/output signal circuit. In fail-safe mode, even if the select lever is “D” or “M” mode, the transmission is fixed in 2nd or 4th (depending on the breakdo w n pos it i on ), so th e cu st om er s ho ul d fe el “sl i pp ing” o r “ p oor ac ce ler at ion” . Wh en fai l- s afe mod e is triggered, when the ignition switch is switched “ON”, the A/T CHECK indicator lamp flashes for about 8 seconds. (Refer toAT-103, " Even when the electronic circuits are normal, under special conditions (for example, when slamming on the brake with the wheels spinni ng drastically and stopping the tire rotation), the transmission can go into fail-safe mode. If this h appens, swi tch “OFF” the i gnition s witch for 10 seconds, then switc h it “ON” ag ain to retu rn to the normal shift pattern. Also, the A/T CHECK indicator lamp flashes for about 8 seconds once, then is cleared. Therefore, the customer's vehicle has returned to normal, so handle according to the “diagnostics flow” (Refer to AT-45

TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)" ).

FAIL- SAFE FUNCTION

If any malfunction occurs in a sensor or sole noid, this function controls the A/T to make driving po ssible.

Vehicle Speed Sensor

● Signals are input from two systems - from vehicle speed sensor A/T (revolution sensor) installed on the

transmission and from combination meter so normal driving is possible even if there is a malfunction in one of the systems. And if vehicle speed sensor A/T (revolution sensor) has unusual cases, 5th gear and manual mode ar e prohibited.

Accelerator Pedal Position Sensor

● If there i s a malf uncti on in on e of th e system s, th e accel erat or open ing an gle is contr oll ed by ECM accor d-

ing to a pre-determi ned accelerator ang le to make driving po ssible. And if the re are malfunction s in tow systems, the engine speed is fixed by ECM to a pre-determined engine speed to make driving possible.

Throttle Position Sensor

● If there i s a malf uncti on in on e of th e system s, th e accel erat or open ing an gle is contr oll ed by ECM accor d-

ing to a pre-determi ned accelerator ang le to make driving po ssible. And if the re are malfunction s in tow systems, the acce lerat or open ing a ngle i s con trolle d by th e idle signa l sent from th e ECM whic h is ba sed on input indicating either idle condition or off-idle condition (pre-determined accelerator opening) in order to make driving possible.

PNP Switch

● In t he un like ly eve nt that a malf unc tion si gnal ente rs the T CM, th e posi tion in dic ator is swi tche d “OFF” , the

starter relay is switched “OFF ” (starter starting is disabled), and t he position is fixed to t he “D” range to make driving possible.

Starter Relay

● The starter relay is switched “OFF”. (Sta rter starting is disabled.)

INTRODUCTION

The TCM receives a sign al fro m the vehi cle s peed sens or, accelerator pedal posi tion s ens or (thro ttle po siti on sensor) or PNP switch and provides shift control or lock-up con trol via A/T solenoid valves. The TCM also communicates with the ECM by means of a signal sent from sensing elements used with the OBD-related parts of the A/T system for malfu nction-diagnostic purpo ses. The TCM is capable of diagno si ng malfunctioning parts while the ECM ca n s t o re malfunctions in its memory. Input and output signals must always be correct and stable in the operation of the A/T system. The A/T system must be in good operating condition and be free of valve seizure, solenoid valve malfunction, etc.

SAT631IB

It is much more difficult to diagnose an error that occurs intermittently rather than continuously. Most intermittent errors are caused by poor electri c conn ections or imp roper w iring. In t his ca se, car eful checking of suspected circuits ma y help p revent the replacem ent of good parts. A visual chec k on ly m ay not fi nd th e cau se o f the e rror s. A roa d tes t with CONSULT-II (or GST) or a circuit tester connected should be performed. Follow the AT-45, "

Before undertaking a ctual checks, take a fe w minutes to talk with a customer who approaches with a driveability complaint. The customer can supply good information about such errors, especially intermittent ones. Find out what symptoms are present and under what condit ions they occur.
