AAT470A
+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.
MEF040DA
+Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-58.)
SAT652J
+After performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
+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 ªChanging CVT Fluidº in
the MA section when changing CVT fluid.
Service Notice or PrecautionsNLAT0004FAIL-SAFENLAT0004S01The 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 ªLº or ªDº. The customer may com-
plain of sluggish or poor acceleration.
When the ignition key is turned ªONº following Fail-Safe operation, SPORT indicator lamp blinks for about 8
seconds. [For ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º, refer to AT-28.]
The blinking of the SPORT indicator lamp for about 8 seconds will appear only once and be cleared. The cus-
tomer may resume normal driving conditions.
Always follow the ªWORK FLOWº (Refer to AT-44).

Precautions (Cont'd)
AT-7

IntroductionNLAT0017The CVT system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (EURO-OBD) performed by the TCM in combi-
nation 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 EURO-
OBD self-diagnostic items. For detail, refer to AT-28.
EURO-OBD Function for CVT SystemNLAT0018The ECM provides emission-related on board diagnostic (EURO-OBD) functions for the CVT system. One
function is to receive a signal from the TCM used with EURO-OBD-related parts of the CVT system. The sig-
nal is sent to the ECM when a malfunction occurs in the corresponding EURO-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.
EURO-OBD Diagnostic Trouble Code (DTC)NLAT0020HOW TO READ DTC AND 1ST TRIP DTCNLAT0020S01DTC 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.)
+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 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.
