PRECAUTIONS

[RE4F04B]

PRECAUTIONS PFP:00001

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

UCS000M9

The Supplemental Re straint System such as “AIR BAG” and “SEAT BELT PRE-TENS IONER”, 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 be lt switch inputs and dual stage front air bag mod ules. 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, whi ch could incr ease 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 maintenance, inc luding incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional activ atio n of the system. For r e mo va l o f Spi ral Cable and Air 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 iden tified by yellow and/or orange harnesses or harness connectors.

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

UCS000MA

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 ignitio n switch OFF and disconne ct the negative battery term inal 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 unne cessary malfunction information (repairs completed) from the TCM or

ECM before returning the vehicle to the custom er.

Precautions

● Before connecting or dis connecting the TCM harness con-

nector, turn ignition switch OFF and disconnect negative battery terminal. Failure to do so may damage the TCM. Because battery voltage is applied to TCM even if ignition switch is turned off.

from TCM, take care not to damage pin term inals (bend or break). Make sure that th ere are not any bends or breaks on TCM pin terminal, when connecting pin connectors.

● Before replacing TCM, perform TCM input/output signal

inspection and make s ure whether TCM fu nctions properly or not. Refer to AT-99, "

TCM INSPECTION TABLE" .

[RE4F04B]

MEF040DA

● After performing each TROUBLE DIAGNOSIS, perform

“DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”. The DTC should not be displa yed in the “DTC CONFIRMATION PROCEDURE” if the repair is completed.

● Before proceeding with disassembly, thoroughly clean th e out-

side of the transaxle. 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 transaxle.

● Place disassembled 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 valve bo dy co ntains precis io n parts and r equi r es ex tre me ca re w hen parts are rem ov ed an d s erv ic ed .

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

● Properly installed valves, sle ev e s, 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.

● Clean or replace ATF cooler if excessive forei gn mate rial is fo und in oi l pan or clog ging strain er. Refer to

AT-11, "

Service Notice or Precautions

UCS000MC

FAIL-SAFE

The TCM has an electronic Fail-Safe (limp home mode). Th is allows t he vehicl e to be dri ven even if a major electrical input/output device circuit is damaged. Under Fail-Safe, th e vehicle alw ays runs in third g ear, even with a shift lever po sition of 1, 2 o r D. The customer may complain of sluggish or poor acceleration. When the ignition key is turned ON following Fail-Safe operation, A/T CHECK indicator lamp blinks for about 8 seconds. [For “TCM Self-diagnostic Procedure (No Tools)”, refer to AT- 5 4 , "

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

The blinking of the A/T CHECK indicator lamp for about 8 seconds will appear only once and be cleared. The customer may resume normal driving conditions. Always follow the “Wor k F l ow” (Refer to AT-63, "

Work Flow" ).

The SELF-DIAGNOSIS results will be as follows:

● The first SELF -DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.

● During the next SELF-DIAGNOSIS, performed after checking the senso r, no damages will be indicated.

TORQUE CONVERTER SERVICE

The torque converter should be replaced under any of the following conditions:

● External leaks in the hub weld area.

● Converter hub is scored or damaged.

● Converter pilot is broken, damaged or fits poorly into crankshaft.

● Steel particles are found after flushing the cooler and cooler lines.

● Pump is damaged or steel particle s are foun d in the con ve rte r.

● Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses

have been made. (Converter clutch material may be glazed.)

● Converter is contaminated with engine coolant containing antifreeze.

● Internal failure of stator roller cl utc h .

● Heavy clutch debris due to overheating (blue converter).

● Steel particles or clutch lining materi al foun d in f luid fi lter or on mag net wh en no interna l parts in unit are

worn or damaged — indicates that lining material came from converter. The torque converter should not be replaced if:

● The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.

● The threads in one or more of the converter bolt holes are damaged.

● Transaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate

lining material in unit and inside the fluid filter.

● Vehicle has been exposed to high mileage (only). The exception may be where the torque converter

clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, such as taxi, delivery or police use.

ATF COOLER SERVI CE

At Low Fluid Temperature

● Fluid viscosity and frictional characteristics of the clutch facing change with fluid temperature. Clutch

engaging or band-contacting pressure is compensated for, according to fluid temperature, to stabilize shifting quality.

AT-32

Page 47

OVERALL SYSTEM

● The line pressure is reduced below 60°C (140°F) to prevent

shifting shock due to low viscosity of automatic transmission fluid when te mperature is low.

● Line pressure is increased to a maximum irrespective of the

throttle openin g when fluid temperature dro ps to −10°C (14°F). This pressure rise is adopted to prevent a delay in clutch and brake operation due to extreme drop of fluid viscosity at low temperature.

SHIFT CONTROL

The shift is regulated entirely by electronic control to accommodate vehicle speed and varying engine operations. This i s accomplished by e lectrical signals transm itted by the revolution sensor and the ECM (throttle opening). This results in improved acceleration performance and fuel economy.

Control of Shift Solenoid Valves A and B

The shift sole noid valve perfor ms simple ON-OFF op eration. When set to ON, the drain circu it cl os es and pilo t pre ssure is ap pl ied to the shift valve. The TCM activa tes shift solenoid valv es A and B according t o signals from the ECM (throttle opening) and revolution sensor to select the optimum gear p osition on the basis of the shift sc hedule me morized in the TCM.

Control of Shift Valves A and B

Pilot pressure generated by the operation of shift solenoid valves A and B is applied to the end face of shift valves A and B. The drawing above shows the operation of shift valve B. When the shift solenoid valve is ON, pilot pressure applied to the end face of the shift valve overcomes spring force, moving the valve upward.

LOCK-UP CONTROL

The torque converter clutch piston in the torque converter is locked to eliminate torque converter slip to increase powe r transmis sion effici ency. The solenoid valve is contro lled by an ON-O FF duty signal sent from the TCM. The signal is converted to an oil pressure signal which controls the lock-up piston.

Conditions for Lock-up Operation

When vehicle is driven in 3rd or 4th gear positions, vehicle speed and throttle opening are detected. If the detected values fall within the lock-up zone memorized in the TC M, lock-up is performed.

Torque Converter Clutch Solenoid Valve Control

The torque converter clutch solenoid valve is controlled by the TCM. The plunger closes the drain circuit during the OFF period, and opens the circuit during the ON period. If the percentage of OFF-time increases in o ne cycle, th e pilot pr essure drain tim e is reduce d and pilot pressure remains hi gh.

LOCK-UP RELEASED

The OFF-duration of the torque converter clutch solenoid valve is long, and pilot pressure is high. The pilot pressure pushes the end face of the torque converter clutch control valve in combination with spring force to move the valv e t o th e le ft .

LOCK-UP APPLIED

When the OFF-duration of the torque converter clutch solenoid valve is short, pilot pressure drains and becomes low. Accordingly, the control valve moves to the right by the pilot pressure of the other circuit and converter pressure. A s a result, converter pressure is app lied to chamber B, keeping the torq ue converter clutch piston applied. Also smooth lock-up is provided by transient application an d release of the lock-up.

OVERRUN CLUTCH CONTROL (ENGINE BRAKE CONTROL)

Forward one-way clutch is used to reduce shifting shocks in downshifting operations. This clutch transmits engine torque to the wheels. However, drive force from the wheels is not transmitted to the engine because the one-way clutch rotates idle. This mean s the engine brak e is not effective. The overrun clutch operates when the engine brake is needed.

Overrun Clutch Solenoid Valve Control

The overrun clutch solenoid valve is operated by an ON-OFF signal transmitted by the TCM to provide overrun clutch control (engine brake control). When this solenoid valve is ON, the pilot pressure drain port closes. When it is OFF, the drain port opens. During the solenoid valve ON pilot pressure is applied to the end face of the overrun clutch contr ol valve.

Overrun Clutch Control V alve Operation

When the sole no id va lv e is O N , p ilo t p res s ure is applied to the o ve rrun clutch control valve. This pushes up the overrun clutch control valve. The line pressure is then shut off so that the clutch does not engage. When the solenoid valve is OFF, pilot pressure is not generated. At this point, the overrun clutch control valve moves downward by spring force. As a result, ov errun clutch operation pressure is provided by the overrun clutch reducing valve. This causes the overrun clutch to engage. In the 1st position, the overrun clutch control valve remains pushed down so that the overrun clutch is engaged at all times.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION PFP:00000

Introduction

The A/T system has two self-diagnostic systems. The first is the emiss ion-related on board diagnosti c system (OBD-II) performed by the TC M (transmission control module) in combination with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is st ored as a DTC in the ECM memory but not the TCM memory. The second is the TCM original self-diagnosis indicated by the A/T CHECK indicator lamp. The malfunction is stored in the TCM me mory. The detected items are overl apped with OBD-II se lf-diagn ostic ite ms. For details, refer to AT-39, "

OBD-II Function for A/T System" .

UCS000MO

OBD-II Function for A/T System

UCS000MP

The ECM provides emission-rel ated on boa rd diagnos tic (OBD-II) functi ons for the A/T system. O ne 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 malfunction occurs in the corresponding OBD-related part. The other function is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel. Sensors, switches and solenoid valves are used as sensing elements. 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

UCS000MQ

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 with such a memory function.

TWO TRIP DETECTION LOGIC

When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC (diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — First Trip If the same malfunction as that experienced during the first test drive is sensed during the second test drive, the MIL will illuminate. — Second Trip A/T-related parts for which the MIL illuminates during the first or second test drive are listed below.

OBD-II Diagnostic Trouble Code (DTC)

UCS000MR

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) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,

P0720, P0725, etc. These DTCs are prescribed by SAE J2012. (CONSULT-II also displays the malfunctioning component or system.)

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

● Output of the diagnost ic trouble co de indicates th at the indica ted circuit has a malfunctio n. 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 a s shown below. Therefore , using CONSULT-II (if available) is recommended.

AT-39

Page 54

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

A sample of CONSULT-II display for DTC and 1st trip DTC is shown in the following page. DTC or 1st trip DTC of a malfunction is displayed in “SELF DIAGNOSIS” mode for “ENGINE” with CONSULTII. Time data indicates how ma ny times the v ehicle was driv en after the last detection of a DTC.

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

[RE4F04B]

SAT014K

SAT015K

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

SAT016K

Freeze Frame Data and 1st Trip Freeze Frame Data

The ECM has a m emory function, which stores the driving co ndition such as fuel sy stem status, calculat ed load value, engin e coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle speed at the moment the ECM detects a malfunction. Data which are stored in the ECM mem ory, along with the 1st t rip DTC , are called 1st trip free ze fram e data, and the data, stored t ogeth er wit h the D TC data , are c alled f reeze f rame data and displa yed on CONS ULT-II or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For details, refer to EC-58, " Only one set o f freez e fram e da ta (either 1st tri p free ze fra me d ata of free ze fra me data) c an be store d in t he ECM. 1st trip freez e frame data is s tored in the ECM me mory al ong w ith t he 1s t trip DT C. Th ere is no priori ty for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. 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. Re me mber, only one set of fre eze f ram e data ca n be st ored i n the ECM . Th e ECM ha s the following priorities to update the data.

NOTICE:

1. The CONSULT-II elect r ic all y d is pl a ys sh if t ti mi ng and l ock - up t i mi ng ( t hat i s, o pe rat io n t im in g of e ac h so le noid). Check for time difference between actual shift timing and the CONSULT-II display. If the difference is noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical parts using applicable diagnostic procedures.

2. Shift sche dule (which im plie s gear po si tion) di spla yed on CONSULT-II and that indicated in Service Manual may differ slightly. This occurs because of the following reasons:

– Actual shift schedu le ha s mo re or les s tol era nc e or allowa nc e, – Shift schedul e indicated in Service Manual refers to the point where shifts start, and – Gear position displayed on CONSULT-II indicates the point where shifts are completed.

3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is displayed upon completion of shifting (which is computed by TCM).

4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II unit.

SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.

1. Touch on CONSULT-II, touch “START (NISSAN BASED VHCL)”, and touch “ENGINE” for OBD-II detected items or touch “A/T” for TCM self-diagnosis . If A/T is not displayed, check TCM power supply and ground circuit. Refer to AT-102, "

TROUBLE DIAGNOSIS - INTRODUCTION

TROUBLE DIAGNOSIS - INTRODUCTION PFP:00000

Introduction

The TCM receives a signal from the vehicle speed sensor, ECM (throttle openin g) or park/n eutral po sitio n (PNP) sw itch and p rovid es shift control or lock-up contro l via A/T solenoid valves. The TCM also communicates wit h the ECM by means of a signal sent from sensing el ements used with the OBD-rel ated parts of the A/T system for m alfunction-diagno stic purposes. The TCM is capable of diagnosing malfunctioning parts while the ECM can store malfunctions in its memory. Input and output signals must always be correct and stable in the operation of th e A/T sy stem. T he A/T system m ust be in good oper ating condition and be free of valve seizure, solenoid valve malfunction, etc.

It is much more difficult to diagnos e a problem th at occurs interm ittently rather than continuously. Most intermittent problems are caused by poor electric connections or improper wiring. In this case, careful checking of sus pect ed circui ts may he lp prev ent th e repla cement of good parts. A visual che ck only, may not find the ca use o f the p roblems . A road test with CONSU LT-II (or GST) or a ci rcuit tester connected should be performed. Follow the “Work Flow”. Refer to AT-63, "

Work Flow" .

UCS000MV

SAT631IA

Before undertaking actual checks, take a few minutes to talk with a customer who approaches with a drive ability complaint. The customer can supply g ood inform ation about s uch probl ems, espec ially intermittent ones. Find out what symptoms are present and under what conditions they occur. A “DIAGNOSTIC WORKSHEET” like the example on page AT-61

should be used. Start your diagnosis by looking for “conventional” problems first. This will help troubles hoot drivea bility proble ms on an electr onically con trolled engine vehicle.

A/T Fluid Cooler Cleaning

UCS0015J

Whenever an au tomatic transaxle is repaired, overhauled, or 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
