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 ªWORK FLOWº (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-DIAGNOSISNCAT0004S04ICVT 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.
IThe self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ªHOW TO ERASE DTCº on AT-16 to complete the repair and avoid
unnecessary blinking of the MI.
For details of OBD, refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº).
ICertain 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, ªDescriptionº, ªHARNESS CONNEC-
TORº.

IntroductionNCAT0017The 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 indi-
cator lamp. The malfunction is stored in the TCM memory. The detected items are overlapped with OBD self-
diagnostic items. For detail, refer to AT-26.
OBD Function for CVT SystemNCAT0018The 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)NCAT0020HOW TO READ DTC AND 1ST TRIP DTCNCAT0020S01DTC 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-Di-
agnostic Results) Examples: 0705, 0710, 0715, 0720, etc. For details, refer to EC section [ªMalfunction
Indicator (MI)º, ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº].
These DTCs are controlled by NISSAN.
2.(
with CONSULT-II orGST)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.)
I1st trip DTC No. is the same as DTC No.
IOutput 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 rec-
ommended.
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 ªENGINEº with CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.
If the DTC is being detected currently, the time data will be ª0º.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
Introduction

IntroductionNCAT0023
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 intermit-
tently 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 ªWork Flowº. Refer to AT-32.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such problems, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A ªDiagnostic Worksheetº like the
example (AT-31) should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.
Also check related Service bulletins for information.
