Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00EEC
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 SRS and SB section of this Service Man-
ual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.
●
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.
●
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 for On Board Diagnostic (OBD) System of A/T and Engine
ECS00EED
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch “OFF” and disconnect the negative battery cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. Will cause the MIL to light up.
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL 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 MIL to light up due to a short circuit.
●
Be sure to connect rubber tubes properly after work. A mis-connected or disconnected rubber
tube may cause the MIL to light up due to a malfunction of the EGR system or fuel injection sys-
tem, etc.
●
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

PRECAUTIONS
2007 Pathfinder
Precautions
ECS00EEE
●
Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch “OFF” and disconnect
negative battery cable. Because battery voltage is applied
to TCM even if ignition switch is turned “OFF”.
●
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
If the repair is completed the DTC should not be displayed
in the “DTC CONFIRMATION PROCEDURE”.
●
Always use the specified brand of ATF. Refer to
MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS"
●
Use lint-free paper not cloth rags during work.
●
After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
●
Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
●
Disassembly should be done in a clean work area.
●
Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
●
Place disassembled parts in order for easier and proper assembly.
●
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
●
Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
●
It is very important to perform functional tests whenever they are indicated.
●
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
●
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
●
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
●
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
●
Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
●
After overhaul, refill the transmission with new ATF.
●
When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to
AT-14, "Changing the A/T Fluid (ATF)"
AT-12, "Checking the A/T Fluid (ATF)"

Service Notice or Precautions
ECS00EEF
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to
. For radiator replacement, refer to
CO-14, "Removal and Installation"
.
OBD-II SELF-DIAGNOSIS
●
A/T self-diagnosis is performed by the TCM in combination with the ECM. Refer to the table on
for the indicator used to display each self-diagnostic result.
●
The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure on
to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD-II, refer to
EC-47, "ON BOARD DIAGNOSTIC (OBD) SYSTEM"
●
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
AT-10
