PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006225819
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. 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” 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 that 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 “SRS AIR BAG”.
 Do not use electrical test equipmen t 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric 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 3 minu tes before performing any service.
Precaution for Trouble DiagnosisINFOID:0000000006216211
AV COMMUNICATION SYSTEM
 Do not apply voltage of 7.0 V or higher to the measurement terminals.
 Use the tester with its open terminal voltage being 7.0 V or less.
 Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
Precaution for Harness RepairINFOID:0000000006216212
AV COMMUNICATION SYSTEM
 Solder the repaired parts, and wrap with tape. [Frays of twisted line must be within 110 mm (4.33 in).]

Screen constitution
Operation Description
 Around view monitor operates by pressing the “CAMERA” switch of multifunction switch and shifting the
selector switch to the reverse position.
 When the selector lever is in any position other t han the reverse position, the screen is switched to the
around view monitor by pressing the “CAMERA” switch.
 The screen is switched to the around view monitor by sh ifting the selector lever to the reverse position.
 In the around view monitor, Birds-Eye view, Front-si de view and rear wide view (rear only) can be switched
by pressing the “CAMERA” switch.
 The around view monitor is cancelled 3 minutes af ter pressing the “CAMERA” switch, and then the screen
returns to the screen before displaying the around view monitor when selector lever is in a position other
than the reverse position.
 ON/OFF setting of sonar indicator display on the Front-Side view screen can be performed.
 In the Birds-Eye view, the invisible area is displa yed on the image to specify the boundary of the 4 cameras.
The invisible area is displayed in yellow in the Birds-Eye view after turning the ignition switch ON.
 The sonar (both of buzzer and indicator) operates only when the camera screen is displayed. NOTE:
The first, second, and third camera image displayed when switched to the camera image display depends
on the settings of “Camera View Priority”.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
DIAGNOSIS SYSTEM (AV CONTROL UNIT)
DescriptionINFOID:0000000006216218
 The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
 Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
On Board Diagn osis FunctionINFOID:0000000006216219
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
 Press the “BACK” switch and the “UP” switch of the 8-direction switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
 The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 The self-diagnosis mode performs diagnoses on the AV control unit, connections between system compo-
nents as well as connections between AV contro l unit and GPS antenna. Then it displays the diagnosis
results on the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system erro r records and system communication status. The checking,
modifying or adjusting generally require human inte rvention and judgment (the system cannot make judg-
ment automatically).
