Nissan Versa (N17): Precautions
Precaution for Supplemental Restraint System
(SRS) "AIR BAG" and "Seat belt pre-tensioner"
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. This system includes seat belt switch inputs and dual stage
front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment,
and may only deploy one front
air bag, depending on the severity of a collision and whether the front
occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB
section of this Service Manual.
WARNING:
- 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 performed by
an authorized NISSAN/INFINITI dealer.
- Improper maintenance, including incorrect removal and installation
of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of
Spiral Cable and Air Bag
Module, see the SR section.
- 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 harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
- When working near the Airbag Diagnosis Sensor Unit or other Airbag
System sensors with the Ignition
ON or engine running, DO NOT use air or electric power tools or strike near
the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air
bag(s), possibly causing
serious injury.
- When using air or electric power tools or hammers, always switch
the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution for Work
- When removing or disassembling each component, be careful not to damage
or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
- When removing (disengaging) components with a screwdriver or similar
tool, be sure to wrap the component
with a shop cloth or vinyl tape to protect it.
- Protect the removed parts with a shop cloth and prevent them from being
dropped.
- Replace a deformed or damaged clip.
- If a part is specified as a non-reusable part, always replace it with a
new one.
- Be sure to tighten bolts and nuts securely to the specified torque.
- After installation is complete, be sure to check that each part works
properly.
- Follow the steps below to clean components:
- Water soluble dirt:
- Dip a soft cloth into lukewarm water, wring the water out of the cloth
and wipe the dirty area.
- Then rub with a soft, dry cloth.
- Oily dirt:
- Dip a soft cloth into lukewarm water with mild detergent (concentration:
within 2 to 3%) and wipe the dirty
area.
- Then dip a cloth into fresh water, wring the water out of the cloth and
wipe the detergent off.
- Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or
gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
General Precautions
- Turn the ignition switch OFF and disconnect the battery cable
from the negative terminal before connecting or disconnecting
the A/T assembly harness connector. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.

- When connecting or disconnecting pin connectors into or
from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin terminal,
when connecting pin connectors.

- Perform TCM input/output signal inspection and check
whether TCM functions normally or not before replacing TCM.
Refer to TM, "Reference Value".

- Perform "DTC (Diagnostic Trouble Code) CONFIRMATION
PROCEDURE".
If the repair is completed DTC should not be displayed in the
"DTC CONFIRMATION PROCEDURE".

- Always use the specified brand of ATF. Refer to MA, "Fluids and
Lubricants".
- Use lint-free paper not cloth rags during work.
- Dispose of the waste oil using the methods prescribed by law, ordinance,
etc. after replacing the ATF.
On Board Diagnosis (OBD) System of A/T and Engine
The ECM has an on board diagnostic system. It will light up the malfunction
indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
- Be sure to turn the ignition switch OFF and disconnect the battery
cable from the negative 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.
- 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.)
- 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.
- 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 EGR system or fuel
injection system, etc.
- Be sure to erase the unnecessary malfunction information (repairs
completed) from the TCM and
ECM before returning the vehicle to the customer.
Removal and Installation Procedure for A/T Assembly
Connector
REMOVAL
Rotate bayonet ring (A) counterclockwise. Pull out A/T assembly
harness connector (B) upward and remove it.

INSTALLATION
1. Align marking (A) on A/T assembly harness connector terminal
body with marking (B) on bayonet ring. Insert A/T assembly harness
connector. Then rotate bayonet ring clockwise.

2. Rotate bayonet ring clockwise until marking (A) on A/T assembly
harness connector terminal body is aligned with the slit (B) on
bayonet ring as shown in the figure (correctly fitting condition).
Install A/T assembly harness connector to A/T assembly harness
connector terminal body.

CAUTION:
- Securely align marking (A) on A/T assembly harness connector
terminal body with bayonet ring slit (B). Then, be
careful not to make a half fit condition as shown in the figure.
- Do not mistake the slit of bayonet ring for other dent portion.

Service Notice or Precaution
OBD SELF-DIAGNOSIS
- A/T self-diagnosis is performed by the TCM in combination with the ECM.
The results can be read through
the blinking pattern of the A/T CHECK indicator or the malfunction indicator
Lamp (MIL). Refer to the table
on "SELF-DIAGNOSTIC RESULTS" for the indicator used to display each
self-diagnostic result. Refer to
TM, "CONSULT Function".
- The self-diagnostic results indicated by the MI are automatically stored
in both the ECM and TCM memories.
Always perform the procedure on "How to Erase DTC" to complete the repair
and avoid unnecessary
blinking of the MI. Refer to TM, "Description".
For details of OBD, refer to TM, "DIAGNOSIS DESCRIPTION : 1 Trip Detection
Diagnosis and 2 Trip
Detection Diagnosis".
- Certain systems and components, especially those related to OBD, may use
the new style slide-locking
type harness connector. For description and how to disconnect, refer to GI,
"Description".
