Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009955588
The Supplemental Restraint System such as “A IR 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 t he 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.

WARNING CHIME SYSTEM : System DiagramINFOID:0000000009462879
WARNING CHIME SYSTEM : System DescriptionINFOID:0000000009462880
DESCRIPTION
• The buzzer for the warning chime system is installed in the combination meter.
• The buzzer sounds when the combination meter receives a buzzer output signal from the BCM.
• The BCM receives signals from various units and transmi ts a buzzer output signal to the combination meter
with CAN communication line if it judges that the warning buzzer should be activated.

LIGHT REMINDER WARNING CHIME : System DescriptionINFOID:0000000009462882
DESCRIPTION
With ignition switch in OFF or ACC position, driver door open, and lighting switch in 1st or 2nd position, the
light warning chime will sound.
• BCM detects ignition switch in OFF or ACC position, front door switch LH ON, and lighting switch in 1st or
2nd position. And then transmits buzzer output signal (li ght reminder warning chime) to combination meter
with CAN communication line.
• When combination meter receives buzzer output signal ( light reminder warning chime), it sounds the buzzer.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled• Lighting switch is at 1st or 2nd position

DESCRIPTION
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.
• BCM receives seat belt buckle switch LH (driver seat) signal from combination meter via CAN communica- tion.
• BCM detects ignition switch turned ON and seat belt buckle switch LH (driver seat) is ON, and then transmits
buzzer output signal (seat belt warning chime) to combination meter via CAN communication.
• When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled• Ignition switch OFF→ON
• Seat buckle switch LH (driver seat) is ON (driver seat belt not fastened)

SYSTEM
• The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control
unit) via CAN communication line.
• The combination meter judges whether the parking brak e is released using the parking brake switch signal
from the parking brake switch, and s ounds the warning buzzer if necessary.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled• Vehicle speed is approximately 4.3 MPH (7 km/h) or higher
• Parking brake switch ON
WARNING CANCEL CONDITIONS

DIAGNOSIS SYSTEM (METER)
DescriptionINFOID:0000000009941189
COMBINATION METER SE LF-DIAGNOSIS MODE
The following meter functions can be checked during Combination Meter Self-Diagnosis Mode:
• Pointer sweep of speedometer, tachometer and gauges.
• Illumination of all LCD segments and color patterns for meter displays.
• Illumination of all lamps/LEDs that are controlled by the combination meter (regardless of switch status).
STARTING COMBINATION METER SELF-DIAGNOSIS MODE
NOTE:
• Check combination meter power supply and ground circuits if self-diagnosis mode does not start. Refer to
MWI-58, "COMBINATION METER : Diagnosis Procedure"
. Replace combination meter if power supply and
ground circuits are found to be normal and self-diagnosis mode does not start. Refer to MWI-82, "Removal
and Installation".
• Combination meter self-diagnosis mode will function with the ignition switch in ON. Combination meter self-
diagnosis mode will exit upon turning the ignition switch to OFF.
How to Initiate Se lf-Diagnosis Mode
1. Press and hold the trip reset switch while turning the ignition switch ON. After 2 seconds release trip reset
switch, then press the trip reset switch 3 times withi n 7 seconds after the ignition switch is turned ON.
2. When the diagnosis function is activated, the meter illuminates all of the following:
• Warning lights/indicators.
• Meter assembly.
• Information display color bars red, green, blue and white (1).
• Odometer, trip A/B odometers and CVT indicator LCD display segments (2).
3. Pressing and holding the trip reset switch performs the pointer sweep test.
CONSULT Function (METER/M&A)INFOID:0000000009941190
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and no-start condition.
