DescriptionINFOID:0000000001374712
Fuel gauge needle will not move from a certain position.
Diagnosis ProcedureINFOID:0000000001374713
1.CHECK COMBINATION METER INPUT SIGNAL
1. Select “METER/M&A” on CONSULT-III.
2. Using “FUEL METER” of “DATA MONITOR”, compare the monitor value with the fuel gauge reading on
the combination meter. Refer to MWI-29, "
Component Function Check".
Does monitor value match fuel gauge reading?
YES >> GO TO 2
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
2.CHECK FUEL LEVEL SENSOR SIGNAL CIRCUIT
Check the fuel level sensor signal circuit. Refer to MWI-29, "
DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
3.CHECK FUEL LEVEL SENSOR UNIT
Perform a unit check for the fuel level sensor unit. Refer to MWI-30, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4
NO >> Replace fuel level sensor unit and fuel pump. Refer to FL-8, "
Removal and Installation".
4.CHECK FLOAT INTERFERENCE
Check that the float arm does not interfere or bind with any of the components in the fuel tank.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-94, "Removal and Installation".
NO >> Repair or replace malfunctioning parts.

 The displayed ambient air temperature is lower than the actual temperature.
Diagnosis ProcedureINFOID:0000000001538674
NOTE:
Check that the symptom is not applicable to the normal operating condition before starting diagnosis. Refer to
MWI-17, "
INFORMATION DISPLAY : System Description".
1.CHECK AMBIENT SENSOR SIGNAL CIRCUIT
Check the ambient sensor signal circuit. Refer to MWI-34, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair harness or connector.
2.CHECK AMBIENT SENSOR UNIT
Perform a unit check for the ambient sensor. Refer to HAC-131, "
Ambient Sensor Component Inspection"
(without NAVI) or HAC-245, "Ambient Sensor Component Inspection" (with NAVI).
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-94, "Removal and Installation".
NO >> Replace ambient sensor.

OUTSIDE AIR TEMPERATURE
The displayed outside air temperature on the information display may differ from the actual temperature
because it is a corrected value calculated from the ambient sensor signal by the combination meter. Refer to
MWI-17, "
INFORMATION DISPLAY : System Description" for details on the correction process.

POWER WINDOW MAIN SWITCH
It changes to condition before initialization and the following functions do not operate when switched to fail-
safe control.
 Auto-up operation
 Anti-pinch function
 Retained power function
Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or in motor.
Error Error condition
Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
Both pulse sensors mal-
functionWhen both pulse signals have not been detected for more than the specified value during glass open/
close operation.
Pulse direction malfunctionWhen the pulse signal that is detected during glass open/close operation detects the opposite condition
of power window motor operating direction.
Glass recognition position
malfunction 1When it detects the error between glass fully closed position in power window switch memory and actual
fully closed position during glass open/close operation is more than the specified value.
Glass recognition position
malfunction 2When it detects pulse count more than the value of glass full stroke during glass open/close operation.
Malfunction of not yet up-
dated closed position of
glassWhen glass open/close operation is continuously performed without fully closing more than the specified
value (approximately 10 strokes).

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001702325
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. 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 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001702326
 Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
 Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have
passed.
 The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front
of the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
 The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
 Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
 Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
 After air bag inflates, the front instrument panel assembly should be replaced if damaged.
