Technician Safety Information

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 SRS 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 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.


Precaution for Battery Service
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.


Precaution for 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 lamp (MIL) 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 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 misconnected or disconnected rubber tube may cause the MIL to light up due to a malfunction of the EVAP 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.


Precaution





^ Before connecting or disconnecting the A/T assembly harness connector, turn ignition switch OFF and disconnect the battery cable from the negative terminal. Because battery voltage is applied to TCM even if ignition switch is turned OFF.





^ After performing each TROUBLE DIAGNOSIS, perform "DTC Confirmation Procedure".
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-10, "Fluids and Lubricants". Fluid Type Specifications
^ 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 A/T. 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 interfere with the operation of the A/T.
^ 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 A/T 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 "Service Notice or Precaution".
^ After overhaul, refill the A/T with new ATF.
^ When the A/T drain plug is removed, only some of the ATF is drained. Old ATF 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.


Service Notice or Precaution



ATF COOLER SERVICE
If ATF 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.

OBD-II 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 AT-80, "CONSULT-III Function (TRANSMISSION)" for the indicator used to display each self-diagnostic result. Consult-III Function (Transmission)
^ The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories.
Always perform the procedure on AT-36, "OBD-II Diagnostic Trouble Code (DTC)" to complete the repair and avoid unnecessary blinking of the MIL. OBD-II Diagnostic Trouble Code (DTC)
^ Certain systems and components, especially those related to OBD, may use the new style slide-locking type harness connector.
