PRECAUTIONSPFP:00001
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)]
PKIA0306E

AT-8
PRECAUTIONS
lVehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
lConverter is contaminated with engine coolant containing antifreeze.
lInternal failure of stator roller clutch.
lHeavy clutch debris due to overheating (blue converter).
lSteel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
lThe fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
lThe threads in one or more of the converter bolt holes are damaged.
lTransaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
lVehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
EURO-OBD SELF-DIAGNOSIS — EURO-OBD —
lA/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the O/D OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the
table onAT-42, "
SELF-DIAGNOSTIC RESULT TEST MODE"for the indicator used to display each self-
diagnostic result.
lThe self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure “HOW TO ERASE DTC” onAT-39, "
HOW TO ERASE DTC"to com-
plete the repair and avoid unnecessary blinking of the MIL.
lThe following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the O/D OFF indicator lamp does not indicate any malfunctions.
–PNP switch
–A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer toAT - 3 7 , "
ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION".
lCertain 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 toPG-70, "
HARNESS CONNECTOR".

When you read wiring diagrams, refer to the following:
lGI-14, "How to Read Wiring Diagrams".

Checking A/T FluidECS004Q7
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of either
range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side of range, add fluid to the charging pipe.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on dipstick.
6. Check fluid condition.
lIf fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-12,
"RADIATOR",CO-15, "RADIATOR (ALUMINUM TYPE)",,.
Changing A/T FluidECS004Q8
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid.
Always refill same volume with drained fluid.
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to “Checking A/T Fluid”. If fluid is still dirty, repeat steps 2 through 5.
