PRECAUTIONS
PRECAUTIONS PFP:00001 Precautions fo r Su ppl em ental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSION ER”, used along with a front sea t belt, h el ps to red uce the ris k or sever ity of injur y to the driv er and f ron t passe nger for certain 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 re ndering t he SRS in operat ive , wh ich co uld increas e t he risk o f personal inj ury or de ath
in the event of a collision which w ould result in air bag inflation, all maintena nce must be per­formed by an authorized NISSAN/INFINITI dealer.
Improper main tenance, includi ng incorrect removal a nd installation of the S RS, can lead to per-
sonal injury caused by un intenti onal act iva tion of t he syste m. Fo r removal o f Spiral Ca ble and Air Bag Modu le, see the SRS section.
Do not use elect rical test equip ment on any circu it related to t he SRS unles s instructed to in this
Service Manual. SR S wiring harnesses can be identified by yellow and /or orange harnesses or harness connectors.

PRECAUTIONS PFP:00001
Precautions f or Supplemental Restraint Syst em (S RS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
ECS00E63
A
The Sup plemental Restraint Syste m such as “AIR BAG” and “SEAT BELT PRE-TENSIONER ”, used along with a fron t seat be lt, hel ps to re duce th e risk or s everity of injur y to th e dr iver and fro nt pass enge r for cer tain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt sw itches to d etermine the fron t air bag dep loyment, and may on ly d eploy one fr ont 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 increase the risk of personal injury or death
in the eve nt of a collision whic h would result in air bag inflation, all mai ntenance must be per­formed by an authorized NISSAN/INFINITI dealer.
Improper maint enance, including i ncorrect removal and installation of the SRS, can lead to per-
sonal injury caus ed by unin te ntional activati on of th e system . For rem oval of Spiral Cab le an d Air Bag Module, see the SRS section.
Do not use electrica l test equipmen t on any circuit relat ed to the SRS u nless instruct ed 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 Engin e ECS00E64
The ECM ha s an on board diagnostic system . It will light up the malfun ction indica tor lamp (MIL) to warn the driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch “OFF” and disconnect the negative battery cable before any
repair or inspection work. The open/short circuit of related switches, sen sors, 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 con nector is free from water, grease, dirt, bent terminals, etc.)
Be sure to route an d sec ure the harnes ses prope rly a fter wo rk. In terfe rence o f the h arness w ith a
bracket, etc. may cause the MIL to light up due to a short circuit.
Be sure t o c onn ect r ubb er tub es p r oper l y af te r wo rk. A mis co nnec te d o r di sc onn ect ed rubb e r tub e
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 unn ecessary malf unction in formation (repairs com pleted) from the TCM and
ECM before returning the vehicle to the customer.

PRECAUTIONS
Before procee ding with disassembl y, thoroughly clean the outside of the tra nsaxle. It is important to pre-
vent the internal parts from becoming contaminated by dirt or other foreign matter.
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 -flamm able solvent befor e 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 body contains prec ision parts and requires extreme care when parts are removed and se rviced.
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 assem bly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protec t O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme car e should be taken to avoid damage to O-rings, seals and gaskets when assembling.
After overhaul, refill the transaxle with new ATF.
When the A/T drain pl ug is removed, only s ome of the fluid is drained . Old A/T fluid will remain i n torque
converter and ATF cooling system. Always follow the procedures under “Changing A/T Fluid” in the A T section when changing A/T fluid. Refer to AT-14, "
Changing A/T Fluid" , AT-14, "Checking A/T Fluid" .
Service Notice or Precautions ECS00E67
ATF COOLER SERVICE
If A/T fluid contains frictional mate rial (clutc hes, ban ds , etc.) , or if an A/T is r epaired, overh auled, or repla ced, inspect and cl ean the A/ T fluid c o oler m ount ed in th e radi ator or re place the ra diator. Flush coo ler lines using cleaning solvent and comp ress ed a ir after repair. For A/T fluid cooler clean ing pro cedur e, refer to AT-15, "
Fluid Cooler Cleaning" . For radiator replacement, refer to CO-15, "RADIATOR" .
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 O/D OFF indicator or the malfunction indicator lamp (MIL). Refer to the table on
AT-75, "
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-41, " unnecessary blinking of the MIL.
For details of OBD-II, refer to AT-40, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
Certain systems and compon ents, especially th ose related to OB D, may u se the new sty le slide-
locking type harness connector. For description and how to disconnect, refer to PG-76, "

A/T Fluid Co oler Cleaning ECS00E6D
Whenever a n automatic transaxle is repaire d, overhauled, or replaced, the A/T fluid cooler mounte d in the radiator must be inspected and cleaned. Metal debris and f riction ma ter ial, if p rese nt, can bec om e trappe d i n the A/T fl uid cool er. This debris c an con­taminate 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 oil pan under the automatic transaxle'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 rema ins in the cool er hose s to drain into the oil pan.

CAN Commu n i c a tion ECS00E6I
SYSTEM DESCRIPTION
CAN (Controll er Area Net work ) is a serial communi cati on line for real time appl icati on. It is an on-ve hicle mul­tiplex communication line with high data communication speed and excellent error detection ability. Many elec­tronic control units are equippe d onto a vehicle, and each control unit share s information and links with other control units during operation (not independen t). In CAN communicati on, control units are connected wi th 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 onl y. For details, refer to LAN-49, "

LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC PATTERN
In order to obtain t he m os t a ppropr iate li ne pres sure char acter istic to mee t th e cur re nt d riving s tate, the TCM controls the pressure control solenoid A current valve and thus controls the line pressure.
Shift Contro l ECS00E6K
The clutch pres sure control solenoid is contr olled by the signals from the s witches and sensors. Thu s, the clutch pressur e is adjusted to be appropriate to the engine load state and vehicle driving state. It becomes possible to finely control the clutch hydraulic pressure with high precision and a smoother shift change charac­teristic is attained.

Lock-up Released
In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
pressure control solenoid valve C and the lock-up apply pressure is drained. In this way, the torque conve rter clutch piston is not coupled.
Lock-up Applied
In the lock-up appli ed state, the torque converter clu tch control valve is set into the locked s tate by the
pressure control solenoid valve C and lock-up apply pressure is generated. In this way, the torque converter clutch piston is pressed and coupled.

SMOOTH LOCK-UP CONTROL
When shifting from the lock-up rel eased state to t he lock -up applied state, the curr ent output to the pres sure control solenoid v alv e C is control led with the T CM. In this way, when shifting to the lock-up app lied state, 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 pressure control solenoid valve C is varied to steadily increase the
pressure control solenoid valve C pressure . In this way, the lock-up apply pressure gradual ly rises and while the torque conver ter clutch piston is put into half-clutched status, the tor que convert er clutch pis ton operating p ressure i s increased a nd the cou­pling is completed smoothly.
Slip Lock-up Control
In the slip region, the pressure control solenoid valve C current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed. This raises the fuel efficiency for 4th and 5th gears at both low speed and when the accelerator has a low degree of opening.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM PFP:00028 Introduction ECS00E6M
The A/T system has two self-diagnostic systems. The first is the em ission-relat ed on board dia gnostic system ( OBD-II) perfor med by the TCM i n combination with the ECM. The malfun ctio n is ind icate d by th e MIL (m alfuncti on ind icato r lamp ) a nd is s tored as a DTC i n the ECM memory but not the TCM memory. The second is the T CM original self-diagnosi s indicated by the O/D OFF indicator lamp. The malfun ction is stored in the TCM memory. The detected items are overlapped with OBD-II self-diag nostic items. For detail, refer to AT-75, "
SELF-DIAG RESULT MODE" .
OBD-II Function for A/T System ECS00E6N
The ECM provi des emissio n-related on bo ard diagno stic (OBD -II) functions for the A/T s ystem. One f unction is to receive a signal from the TCM used w ith OBD-related parts of the A /T system. The signal is sent to the ECM when a malfunction o ccurs in the corr esponding OBD- related part. The ot her function is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) o n the instrument panel. Sensors, switches and solenoid valves are use d as sensing el ements. 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-I I ECS00E6O
ONE TRIP DETECTION LOGIC
If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored i n the ECM memory as a D TC. The TCM is not provided with such a memory function.
TWO TRIP DETECTION LOGIC
When a ma lfunction is sens ed during the f irst test drive, it is stored in the EC M memory as a 1st trip DT C (diagnostic trouble code) or 1st trip freeze frame data. At this point, the MI L will not illuminate. — 1st Trip If the same mal function as th at experienc ed during the first test driv e is sensed du ring the s econd test driv e, the MIL wil l illuminate. — 2nd 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) ECS00E6P
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 (Gener ic S can Tool) Examples: P 0705, P0710 etc.
These DTC are prescribe d by SAE J2012. (CONSULT-II also displays the malfunc tioning component or system.)
1st trip DTC No. is the same as DTC No.
Output of the dia gno stic t roub le c ode indica tes t hat th e in dicat ed c ircui t has a m alfun ction . Ho w -
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 CO NS ULT-II display for DTC and 1st tr ip DT C is sho wn on the next page. DT C or 1st tri p DTC o f a malfunctio n is displayed in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CON­SULT-II. Time data indicates how many times the vehicle was driven after the last detection of a DTC.

Freeze Frame Data and 1st Trip Freeze Frame Data
The ECM has a memory function, which stores the driving condition such as fuel system status, calculated load value, en gine coolant temperature, sh ort term fuel trim, long term fuel tr im, engine sp eed and vehicle speed at the moment the ECM detects a malfunction. Data which are store d in the ECM memory, along with the 1st trip DTC, are called 1st trip fr eeze frame da ta, and the data, stored together wit h the DTC data, are called freeze fr ame data and disp layed on CON SULT-II or GST. The 1st trip freeze fram e data can only be dis played on the CO NSU LT-II screen, not on the GST. For detail, refer to EC-53, "
FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" .
Only one set of fre eze fr ame d ata (e ither 1s t trip f reeze fram e data of fr eeze fr am e data) can be store d in the ECM. 1st trip fr eeze fram e da ta is stor ed in the ECM mem ory al on g with t he 1st tr ip DT C . There is no priori ty for 1st trip freeze frame data and it is updated each tim e a differen t 1st trip D TC is de tected. However, once freeze frame data (2nd trip detection /MIL on) is sto red in the ECM me mory, 1st trip freeze fram e data is no longer store d. Re memb er, only one set of freeze fr am e data can be st ored in the EC M. The E C M has th e fol­lowing priorities to update the data.
Priority Items
1 Freeze frame data Misfire — DTC: P0300 - P0306
Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175 2 Except the above items (Includes A/T related items) 3 1st trip freeze frame data
Both 1st tr ip fre eze fr ame data a nd freeze frame data ( along wi th the DT C) are c leared w hen the ECM me m­ory is eras ed.
HOW TO ERASE DTC
The diagnostic trouble code can be er ased by CONSULT-II, GST or ECM DIAGNOSTIC TEST M ODE as described following.
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 the ECM.
The following em ission-related diagnostic i nformation is cleared from th e ECM memory when erasing DT C related to OB D-II. For details, refer to EC-49, "

How To Perform Trouble Diagnosis For Quick and Accurate Repair ECS00E6T
INTRODUCTION
The TCM receives a signal from the vehicle sp eed signal , ECM (throttle open in g) or PNP switch and provi des shift control or lock-up control via A/T solenoid valves. The TCM also communicate s with the ECM by means of a signal sent from sen sing elem ents used with t he OBD-related parts of the A/T system for malfu nction-diagnostic purposes . The TCM is capa­ble of diagnosing malfunctioning parts while the ECM can store mal­functions in i ts memory. Input and output signals must always be correct a nd stable in the operation of the A/T system. T he A/T system m ust b e in go od oper ­ating condition an d be fr ee o f valve sei zur e, soleno id valve m alfunc ­tion, etc.

TROUBL E DIAGNOSI S
It is much more difficult to diagnose an error that occurs intermit­tently rather than continuous ly. Most intermittent errors are caus ed by poor electric conn ections or improper wiring . In this case, c areful checking of s uspect ed circuits may he lp prev ent the repl acement o f good parts. A visual check on ly may not find the c au se of th e er rors. A r oad t est with CONSULT-II (or GST) or a circuit tester connected should be performed. Follow the AT-48, "
Before und ertaking actual chec ks, take a few 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 sym ptoms are present and u nder what condition s they occur. A “Diagnostic Worksheet” as shown on the example (Refer to AT-49 Start your diagnosis by looking for “conventional” errors first.

DATA MONITOR MODE
NOTICE:
1. The CONSULT - II electrically displays shift timing and lock-up timing (that is, operation timing of each sole­noid). Check for time difference between actual shift timing and the CONSULT-II display. If the difference is noticeable, mecha nica l parts (exce pt solenoi ds, s en sors, etc.) may be malfun ct ioning. C hec k mechan ical parts using applicable diagnostic procedures.
2. Shift sch edule ( which i mplie s gear position ) display ed on C ONSU LT-II and that indica ted in Servi ce Man ­ual may differ slightly. This occurs because of the following reason s:
Actual shift schedule has more or less tolerance or allowance, Shift schedule 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. Displ ay of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed upon complet ion of shifting (which is computed by TCM).

DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE PFP:23710 Description ECS00E77
CAN (Controller Area Network) is a serial communication l ine for real time application. It is an on-vehicle mul­tiplex communication line with high data communication speed and excellent malfunction detection ability. Many ele ctronic c ontrol u ni ts are e quippe d onto a veh icle, and e ac h contr ol u nit s ha res inform ation a nd links with other control units during operation (not independent). In CAN communication, control units are con­nected with 2 c ommun ication line s (CAN- H line, CAN -L line) all owing a hi gh rate of information t ransm ission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis Logic ECS00E78
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “CAN COMM CIRCUIT” with CONSULT-II or U1000 without CONSULT-II is
detected when TCM cannot communicate to other control units.
Possible Cause ECS00E79
Harness or connectors (CAN communication line is open or shorted.)
DTC Confirmation Procedure ECS00E7A
NOTE: If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF” and wait at least 10 secon ds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminat ed.
WITH CONSULT-II
1. Turn ignition switch “ON”. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-II.
3. Start engine.
4. Drive vehicle and mai ntain the following condition for a t least 6 seconds.
SLCT LVR POSI: “D” position
5. If DTC is detected, go to AT-86, "
