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.

If a 1st trip DTC is stored in the ECM, the time data will be ª1tº.
Freeze Frame Data and 1st Trip Freeze Frame DataNCAT0020S0101The 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 (ªCONSULT-IIº, ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº).
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 prior-
ity 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-
ityItems
1 Freeze frame data Misfire Ð DTC: P0300 - P0306 (0300 - 0306)
Fuel Injection System Function Ð DTC: P0171 (0171), P0172 (0172), P0174 (0174), P0175
(0175)
2 Except the above items (Includes CVT related items)
3 1st trip freeze frame data
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 DTCNCAT0020S02The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as
described following.
IIf the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
IWhen you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on the ECM.

HOW TO ERASE DTC (WITH GST)NCAT0020S041. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªOBD SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC section ªGeneric Scan Tool (GST)º.
HOW TO ERASE DTC (NO TOOLS)NCAT0020S051. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.
Malfunction Indicator (MI)NCAT00211. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
IIf the malfunction indicator does not light up, refer to EL sec-
tion (ªWarning Lamps/System Descriptionº, ªWARNING
LAMPS AND CHIMEº).
(Or see MI & Data Link Connectors in EC section.)
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (OBD) malfunction. For detail,
refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM
DESCRIPTIONº).
CONSULT-IINCAT0022After performing ªSELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)º (AT-19), place check marks for results on the ªDIAGNOS-
TIC WORKSHEETº, AT-31. Reference pages are provided follow-
ing the items.
NOTICE:
IAdditional CONSULT-II information can be found in the Opera-
tion Manual supplied with the CONSULT-II unit.
