Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS004Q0
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.
WA RN ING:
lTo 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.
lImproper 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.
lDo 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 harness connectors.
Precautions for On Board Diagnostic (EURO-OBD) System of A/T and Engine —
Euro-OBD —
ECS004Q1
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:
lBe 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 MIL to light up.
lBe 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.)
lBe 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.
lBe 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 EGR system or fuel injection system, etc.
lBe sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precautions For Trouble DiagnosisECS004VN
CAN SYSTEM
lDo not apply voltage of 7.0V or higher to the measurement terminals.
lUse the tester with its open terminal voltage being 7.0V or less.
Precautions For Harness RepairECS004VO
CAN SYSTEM
lSolder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in)]

REMOVAL AND INSTALLATION
3. Install torque converter to drive plate.
lWith converter installed, rotate crankshaft several turns
to check that transaxle rotates freely without binding.
4. Tighten belts fixing transaxle.
5. Reinstall any part removed.
6. Adjust control cable. Refer toAT-456, "
Control Cable Adjust-
ment".
7. Check continuity of PNP switch. Refer toAT-130, "
DTC P0705
PARK/NEUTRAL POSITION (PNP) SWITCH".
8. Refill transaxle with ATF and check fluid level.
9. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through “N” to “D”, to “2”, to “1” and
“R” positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer toAT-69, "
Road Test".

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT

EJS000T0
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.
WAR NIN G:
lTo 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.
lImproper 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.
lDo 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 harness connectors.
Precautions for Working with HFC-134a (R-134a)EJS000T1
WAR NIN G:
lUse only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor failure is likely to occur.
lThe specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
–When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possi-
bletominimizetheentryofmoistureintosystem.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove R-134a from the A/C system, using certified service equipment meeting require-
ments of SAE J2210 (R-134a recycling equipment), or J2209 (R-134a recovery equipment). If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health
and safety information may be obtained from refrigerant and lubricant manufacturers.
–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
General Refrigerant PrecautionsEJS000T2
WAR NIN G:
lDo not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
lAlways wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
lDo not store or heat refrigerant containers above 52°C(125°F).
lDo not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
lDo not intentionally drop, puncture, or incinerate refrigerant containers.
lKeep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
lRefrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
lDo not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and R-134a have been
shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
