PRECAUTION
PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012433111
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 severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for Power Generation Voltage Variable Control SystemINFOID:0000000012433112
CAUTION:
For this model, the battery current sensor that is in stalled 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 direct ly 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 gr ound wire directly to the battery terminal.

Removal and InstallationINFOID:0000000012433138
CAUTION:
To prevent damage to the parts, disconnect the battery cable from the negative terminal first.
REMOVAL
1. Disconnect the battery cable from
the negative terminal. Refer to PG-70, "Exploded View".
2. Remove current sensor nut and separate the current sensor from terminal connector.
3. Disconnect harness connector and remove the current sensor.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Replace the current sensor if it has b een dropped or sustained and impact.
To install the battery, carefully read the following instructions:
• To prevent damage to the parts, connect the battery cable to the positive terminal first.
• After connecting battery cables, to securely supp ly battery voltage, ensure that they are tightly
clamped to battery terminals for good contact.
• To securely supply battery voltage, check battery terminal for poor connection caused by corrosion.

DIAGNOSIS SYSTEM (AIR BAG)
Trouble Diagnosis with CONSULT
INFOID:0000000012430606
1. Connect CONSULT.
2. DTC is displayed on SELF-DIAG RESULTS.
NOTE:
If a malfunction is not detected on “SELF-DIAG RESULTS [CURRENT]”, but a malfunction is detected during
SRS Operation Check, the following cases may exist:
• “SELF-DIAG [PAST]” memory might not be erased. Refer to SRC-14, "
On Board Diagnosis Function".
• SRS system malfunctions intermittently. Refer to SRC-41, "
InspectionProcedure".
DIAGNOSIS MODE
1. Connect CONSULT.
2. Confirm that zero point reset of OCS is complete.
3. If no DTCs are detected on “SELF-DIAG RESULTS [CURRE NT]”, repair of SRS is completed. Go to step
4.
If any DTCs are detected on “SELF-DIAG RESULT S [CURRENT]”, the malfunction has not been repaired
completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to SRC-
14, "On Board Diagnosis Function".
4. Touch “ERASE”. NOTE:
Touching “ERASE” will clear the SRS memory of the malfunction (“SELF-DIAG [PAST]”). If “SELF-
DIAG [PAST]” is not erased, User Mode may sh ow the previous system malfunction even if the
malfunction has been repaired completely.
5. Check that no malfunction is det ected in “SELF-DIAG [PAST]”.
6. Exit Diagnosis Mode and disconnect the CONSULT.
7. Perform SRS Operation Check. Refer to SRC-14, "
On Board Diagnosis Function".
SRS HISTORY CHECK
1. Check repair history of the SRS. If no repairs have been made, perform SRC-14, "On Board Diagnosis
Function". If repairs have been made, GO TO step 2.
2. Erase ”SELF-DIAG [PAST]” after repair. Refer to SRC-14, "
On Board Diagnosis Function".
CONSULT Function (AIR BAG)INFOID:0000000012430607
CONSULT can display each diagnostic item using the diagnostic test modes shown following.
Diagnostic Test ModeDiagnostic Item Description
Self Diagnostic Result SEL F-DIAG RESULT [CURRENT]A current Self-diagnosis result (also indicated by the number of
warning lamp flashes in the Diagnosis mode) is displayed on the
CONSULT screen in real time. This refers to a malfunctioning part
requiring repairs.
Data Monitor DATA MONITOR Displays air bag diagnosis sensor unit input/output data in real time.
ECU Identification ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identifica-
tion number) or part number is displayed. Air bag diagnosis sensor
unit has individual ECU discriminated number (identification num-
ber) or part number based on model and equipment.
Trouble Diagnostic Record TR OUBLE DIAG RECORD [PAST] With TROUBLE DIAG RECORD, diagnosis results previously
erased by a reset operation can be displayed on the CONSULT
screen.
