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
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” 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 “Changing CVT Fluid” in
the MA section when changing CVT fluid.

Service Notice or Precautions

NLAT0004

FAIL-SAFE

NLAT0004S01

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 com-
plain of sluggish or poor acceleration.
When the ignition key is turned “ON” following Fail-Safe operation, SPORT indicator lamp blinks for about 8
seconds. [For “TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)”, 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 “WORK FLOW” (Refer to AT-44).

PRECAUTIONS

Precautions (Cont’d)

AT-7

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.

EURO-OBD SELF-DIAGNOSIS

NLAT0004S04

CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the SPORT indicator lamp. Refer to the table on AT-22 for the indicator used to dis-
play 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-19 to complete the repair and avoid
unnecessary blinking of the MI.

For details of EURO-OBD, refer to EC section (“ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION”).

Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to EL section, “Description”, “HARNESS CONNEC-
TOR”.

Introduction

NLAT0017

The 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 System

NLAT0018

The 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)

NLAT0020

HOW TO READ DTC AND 1ST TRIP DTC

NLAT0020S01

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-Di-

agnostic 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 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 “ENGINE” with CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.

SAT250K

If the DTC is being detected currently, the time data will be “0”.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

EURO-OBD

Introduction

AT-18

SAT015K

If a 1st trip DTC is stored in the ECM, the time data will be “1t”.

SAT016K

Freeze Frame Data and 1st Trip Freeze Frame Data

NLAT0020S0101

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 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-

ity

Items

Freeze frame data

Misfire — DTC: P0300 - P0306 (0300 - 0306)
Fuel Injection System Function — DTC: P0171 (0171), P0172 (0172), P0174 (0174), P0175
(0175)

Except the above items (Includes CVT related items)

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 DTC

NLAT0020S02

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.
