Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS002UK
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.

Trouble Diagnosis with Battery/Starting/Charging System Tester (Battery)NKS002UO
CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:

To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be
done as a set from start to finish.

If battery surface charge is detected while testing, the tester will prompt you to turn on the headlamps to
remove the surface charge.

If necessary, the tester will prompt you to determine if the battery temperature is above or below 0 °C (32
° F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to
make the selection.
1. Turn off all loads on the vehicle electrical system. Clean or repair as necessary.
2. Visually inspect the battery, battery terminals and cable ends with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery terminals, reconnect them and restart the test.
3. Connect the red tester lead clamp to the positive battery termi- nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys, select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5. Locate the battery type and rating stamped or written on the
top case of the battery to be tested.
NOTE:
The battery rating will have either of the following.

CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)

JIS: Japanese Industrial Standard.
When using the battery tester: Use the CCA rating only.

The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.

U.S. market : Refer to the latest “Battery Testing” Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.

You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating. NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Use only the CCA choice .

8. Press “ENTER”, then test output code is displayed. Record the test output code on the repair order.
9. Toggle back to the “DIAGNOSTIC SCREEN” for test results. NOTE:

If necessary, the tester will ask the user to determine if the
battery has just been charged. Choose the appropriate selec-
tion by pressing the up or down arrow button and then press
the “ENTER” button to make the selection.

When testing a battery installed in a vehicle that has recently
been driven, select “BEFORE CHARGE”.

If the battery has just been slow charged due to a “CHARGE
& RETEST” decision by the tester, and the tester asks the user “BEFORE CHARGE/AFTER
CHARGE”, select “AFTER CHARGE”.

NIS001UH
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

Service NoticeNIS001UI

When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.

Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.

Apply sealing compound where necessary when installing parts.

When applying sealing compound, be careful that the sealing compound does not protrude from parts.

When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
