PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) ‘‘AIR BAG’’ and ‘‘SEAT BELT PRE-TENSIONER’’
Precautions for Supplemental Restraint System
(SRS) ‘‘AIR BAG’’ and ‘‘SEAT BELT
PRE-TENSIONER’’
The Supplemental Restraint System ‘‘AIR BAG’’ and ‘‘SEAT BELT PRE-TENSIONER’’, used along with a seat
belt, help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used along
with the seat belt helps to reduce the risk or severity of injury to the driver and front passenger in a side collision. The supplemental side air bag consists of air bag modules (located in the outer side of front seats),
satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal collision),
wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision). Information
necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
+ To avoid rendering the SRS inoperative, which could increase the risk 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 dealer.
+ Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ‘‘SEAT BELT PRE-TENSIONER’’ connector) can be
identified with yellow harness connector (and with yellow harness protector or yellow insulation
tape before the harness connectors).
NCAT0002
Precautions for On Board Diagnostic (OBD) System of CVT and Engine
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver
of a malfunction causing emission deterioration.
CAUTION:
+ Be sure to turn the ignition switch ‘‘OFF’’ and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc.
will cause the MI to light up.
+ Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI 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 MI 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 MI to light up due to a malfunction of the EGR system or fuel injection system, etc.
+ Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precautions
+ Before connecting or disconnecting the TCM harness
connector, 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.

Precautions (Cont’d)
PRECAUTIONS
+ When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
Bend
Perform TCM
input/output signal
inspection before
replacement.
Break
SEF291H
+ Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly or not. (See page AT-41.)
MEF040DA
+ After performing each TROUBLE DIAGNOSIS, perform
‘‘DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE’’.
The DTC should not be displayed in the ‘‘DTC CONFIRMATION PROCEDURE’’ if the repair is completed.
SAT652J
+ It is very important to perform functional tests whenever they
are indicated.
+ Extreme care should be taken to avoid damage to O-rings,
seals and gaskets when assembling.
+ When the CVT drain plug is removed, only some of the fluid is
drained. Old CVT fluid will remain in torque converter and CVT
fluid cooling system.
Always follow the procedures under ‘‘Changing CVT Fluid’’ in
the MA section when changing CVT fluid.
Service Notice or Precautions
FAIL-SAFE
NCAT0004
NCAT0004S01
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs even with a shift lever position of ‘‘L’’ or ‘‘D’’. The customer may
complain of sluggish or poor acceleration.
When the ignition key is turned ‘‘ON’’ following Fail-Safe operation, CVT or SPORT indicator lamp blinks for
about 8 seconds. [For ‘‘TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)’’, refer to AT-25.]
Fail-Safe may occur without electrical circuit damage if the vehicle is driven under extreme conditions (such
as excessive wheel spin followed by sudden braking). To recover normal shift pattern, turn the ignition key
‘‘OFF’’ for 5 seconds, then ‘‘ON’’.
AT-6
Page 8
PRECAUTIONS
Service Notice or Precautions (Cont’d)
The blinking of the CVT or SPORT indicator lamp for about 8 seconds will appear only once and be cleared.
The customer may resume normal driving conditions.
Always follow the ‘‘WORK FLOW’’ (Refer to AT-32).
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 sensor, no damages will be indicated.
OBD SELF-DIAGNOSIS
NCAT0004S04
+ CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the CVT or SPORT indicator. Refer to the table on AT-19 for the indicator used to
display each self-diagnostic result.
+ The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ‘‘HOW TO ERASE DTC’’ on AT-16 to complete the repair and avoid
unnecessary blinking of the MI.
For details of OBD, refer to EC section (‘‘ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION’’).
+ Certain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector.
For description and how to disconnect, refer to EL section, ‘‘Description’’, ‘‘HARNESS CONNECTOR’’.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
Introduction
Introduction
NCAT0017
The CVT system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD) performed by the TCM in combination with
the ECM. The malfunction is indicated by the MI (malfunction indicator) and is stored as a DTC in the ECM
memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the CVT indicator (warning) lamp or SPORT indicator lamp. The malfunction is stored in the TCM memory. The detected items are overlapped with OBD selfdiagnostic items. For detail, refer to AT-26.
OBD Function for CVT System
NCAT0018
The ECM provides emission-related on board diagnostic (OBD) functions for the CVT system. One function
is to receive a signal from the TCM used with OBD-related parts of the CVT 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 MI (malfunction indicator) on the instrument panel. Sensors, switches and
solenoid valves are used as sensing elements.
The MI automatically illuminates in Two Trip Detection Logic when a malfunction is sensed in relation to CVT
system parts.
OBD Diagnostic Trouble Code (DTC)
HOW TO READ DTC AND 1ST TRIP DTC
NCAT0020
NCAT0020S01
DTC and 1st trip DTC can be read by the following methods.
1. (
No Tools) The number of blinks of the malfunction indicator in the Diagnostic Test Mode II (Self-
Diagnostic Results) Examples: 0705, 0710, 0715, 0720, etc. For details, refer to EC section [‘‘Malfunction
Indicator (MI)’’, ‘‘ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION’’].
These DTCs are controlled by NISSAN.
2. (
with CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,
P0720, P0725, etc.
These DTCs are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)
+ 1st trip DTC No. is the same as DTC No.
+ Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction.
However, 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, using CONSULT-II (if available) is recommended.
A sample of CONSULT-II display for DTC is shown at left. DTC or 1st trip DTC of a malfunction 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.
SAT651J
If the DTC is being detected currently, the time data will be ‘‘0’’.
AT-15
Page 17
ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
OBD Diagnostic Trouble Code (DTC) (Cont’d)
SAT581J
If a 1st trip DTC is stored in the ECM, the time data will be ‘‘1t’’.
SAT582J
Freeze Frame Data and 1st Trip Freeze Frame Data
NCAT0020S0101
The ECM has a memory function, which stores the driving condition such as fuel system status, calculated
load value, engine 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 memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-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 section (‘‘CONSULT-II’’, ‘‘ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION’’).
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 frame data and it is updated each time a different 1st trip DTC is detected. However,
once freeze frame data (2nd trip detection/MI on) is stored in the ECM memory, 1st trip freeze frame data is
no longer stored. Remember, only one set of freeze frame data can be stored in the ECM.
The ECM has the following priorities to update the data.
Prior-
ity
1 Freeze frame data Misfire — DTC: P0300 - P0306 (0300 - 0306)
Fuel Injection System Function — DTC: P0171 (0171), P0172 (0172), P0174 (0174), P0175
(0175)
2 Except the above items (Includes CVT related items)
3 1st trip freeze frame data
Items
Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM
memory is erased.
HOW TO ERASE DTC
NCAT0020S02
The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as
described following.
+ If the battery terminal 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.

TROUBLE DIAGNOSIS — INTRODUCTION
Introduction
Sensors
Solenoid valves
INFO.
TCM
ECM
SAT631IA
CAUSE
SAT632I
Introduction
NCAT0023
The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up
control via step motor and CVT 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
CVT system for malfunction-diagnostic 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 the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve
malfunction, etc.
It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the ‘‘Work Flow’’. Refer to AT-32.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The customer can supply good information about such problems, especially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A ‘‘Diagnostic Worksheet’’ like
the example (AT-31) should be used.
Start your diagnosis by looking for ‘‘conventional’’ problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.
Also check related Service bulletins for information.
