PRECAUTIONS
Revision: 2006 January2006 M35/M45
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS003NB
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.
WAR NING :
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 Power Generation Voltage Variable Control SystemNKS003NC
CAUTION:
For this model, the battery current sensor that is installed to the battery cable at the negative terminal
measures the charging/discharging current of the battery, and performs various controls. If the electri-
cal component or the ground wire is connected directly to the battery terminal, the current other than
that being measured with the battery current sensor is charging to or discharging from the battery.
This condition causes the malfunction of the control, and then the battery discharge may occur. Do
not connect the electrical component or the ground wire directly to the battery terminal.

7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to SC-8, "
DIAGNOSTIC RESULT
ITEM CHART" .
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 bat-
tery has just been charged. Choose the appropriate selection 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 CHANGE”.
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”.

Diagnostic item Service procedure
GOOD BATTERYBattery is OK, go to “Trouble Diagnosis”, “STARTING SYSTEM”. Refer to SC-13, "
Trouble Diagnosis with
Battery/Starting/Charging System Tester (Starting)" .
REPLACE BATTERYReplace battery.
Before replacing battery, clean the battery cable clamps and battery posts. Perform battery test again with
Battery/Starting/Charging system tester. If second test result is “Replace Battery”, then do so. Perform bat-
tery test again to confirm repair.
BAD CELL-REPLACEReplace the battery. Perform battery test again with Battery/Starting/Charging system tester to confirm
repair.
GOOD-RECHARGEPerform the slow battery charging procedure. (Initial rate of charge is 10 A for 12 hours.) Perform battery
test again with Battery/Starting/Charging system tester.
CHARGE & RETESTPerform the slow battery charging. (Initial rate of charge is 10 A for 12 hours.)
Perform battery test again with Battery/Starting/Charging system tester to confirm repair.
NOTE:
If the tester asks the user “BEFORE CHARGE/AFTER CHARGE”, select “AFTER CHARGE”.
