Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951603
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 the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minutes before performing any service.

ZONE VARIATION SETTING PROCEDURE
The difference between magnetic north and geographica l north can sometimes be great enough to cause
false compass readings. This difference is known as variance. In order for the compass to operate properly
(accurately) in a particular zone, the zone variat ion must be calibrated using the following procedure.
Zone Variation Chart
1. Determine your location on the zone map.
2. Turn the ignition switch to the ON position.
3. Press and hold the mode (N) switch until the current zone number is displayed.
4. Press the mode (N) switch repeatedly until the desired zone number appears in the display.
Once the desired zone number is displayed, stop pres sing the mode (N) switch and the display will show a
compass direction after a few seconds.
NOTE:
Use zone number 5 for Hawaii.
CALIBRATION PROCEDURE
The compass display is equipped with an automatic correct ion function. If the compass display reads “C” or
the direction is not shown correctly, perform the correction procedure below.
1. Press and hold the mode (N) switch until the display reads “C”.
2. Drive the vehicle slowly in a circle, in an open, safe place. The
initial calibration is completed in about three turns.
NOTE:
In places where the terrestrial m agnetism is extremely disturbed, the
initial correction may start automatically.

DIAGNOSIS SYSTEM (METER)
DescriptionINFOID:0000000009461692
COMBINATION METER SELF-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 t he ignition switch in ON. Combination meter self-
diagnosis mode will exit upon turning the ignition switch to OFF.
How to Initiate Self-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 within 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:0000000009461693
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”, potentially causing a di scharged battery and no-start condition.
APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes shown.

W/L ON HISTORY
• “W/L ON HISTORY” indicates the “TIME” when the warning/ indicator lamp is turned on.
• The “TIME” above is:
- 0: The condition that the warning/indicator lamp has been turned on 1 or more times after starting the engine
and waiting for 30 seconds.
- 1 - 39: The number of times the engi ne was restarted after the 0 condition.
- NO W/L ON HISTORY: No warning/indicator lamp history is stored.
NOTE:
• W/L ON HISTORY is not stored for approximately 30 seconds after the engine starts.
• Brake warning lamp does not store any history when the parking brake is applied or the brake fluid level gets
low.
