PRECAUTIONS
[ALL]
PRECAUTIONS
[ALL] PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" ECS006M4
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
q 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 per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness connec-
tors.
Precautions for On Board Diagnostic (EURO-OBD) System of CVT and Engine
ECS006M5
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MI) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
q 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.
q 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.)
q 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.
q 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 fuel injection system, etc.
q Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precautions ECS006M6
q Before connecting or disconnecting the TCM harness con-
nector, 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.
SEF289H
CVT-8
PRECAUTIONS
[ALL]
q When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or A
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
B
CVT
AAT470A
D
q Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. Refer to CVT-46, "TCM Terminals and Reference E
Value" (with EURO-OBD) or CVT-142, "TCM Terminals and
Reference Value" (with EXCEPT EURO-OBD).
F
G
MEF040DA
q After performing each TROUBLE DIAGNOSIS, perform H
"DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE".
The DTC should not be displayed in the "DTC CONFIRMA- I
TION PROCEDURE" if the repair is completed.
J

q It is very important to perform functional tests whenever they are indicated.

Service Notice of Precautions ECS006M7
FAIL-SAFE
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 CVT-29 .]
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 CVT-35 ).
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.

PRECAUTIONS
[ALL]
EURO-OBD SELF-DIAGNOSIS
q 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 for the indicator used to
display each self-diagnostic result.
q 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 to complete the repair and avoid unnec-
essary blinking of the MI.
For details of EURO-OBD, refer to CVT-20, "ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION" .
q 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 PG-86, "HARNESS CONNECTOR" .
Wiring Diagrams and Trouble Diagnoses ECS006M8
q Refer to GI-14, "How to Read Wiring Diagrams" in GI section.
