PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ACS002L3
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 EngineACS002L5
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 termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid 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 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.

Changing A/T FluidACS002LB
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained ATF.

To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling, at the same time drain the old ATF
from the radiator cooler hose return side.

When the color of the ATF coming out is almost same as the
color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% of the stipu-
lated amount.
CAUTION:

Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.

Using ATF other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and A/
T durability, and may damage the A/T, which is not covered by the warranty.

When filling ATF, take care not to scatter heat generating parts such as exhaust.

Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to AT- 1 3 , "
Checking A/T Fluid" . If ATF is still dirty, repeat step 2.
through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt. ATF: Genuine NISSAN Matic J ATF
Fluid capacity: 10.3 (10-7/8 US qt, 9-1/8 lmp qt)
Drain plug: : 34 N·m (3.5 kg-m, 25 ft-lb)

Checking A/T FluidACS002LC
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen the level gauge bolt.
4. Before driving, A/T fluid level can be checked at A/T fluid tem- peratures of 30 to 50 °C (86 to 122 °F) using “COLD” range on A/
T fluid level gauge as follows.
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 A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go. CAUTION:
To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T
fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the A/T fluid temperature approximately 65 °C (149 °F).
NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65 °C (149 °F) using “HOT” range on A/
T fluid level gauge.
