Precaution for Technicians Using Medical Electric
INFOID:0000000010120305
OPERATION PROHIBITION
WARNING:
• Parts with strong magnet is used in this vehicle.
• Technicians using a medical electric device such as pacemaker must never perform operation on the
vehicle, as magnetic field can affect the device function by approaching to such parts.
NORMAL CHARGE PRECAUTION
WARNING:
• If a technician uses a medical electric device such as an implantable cardiac pacemaker or an
implantable cardioverter defibrillator, the possible effects on the devices must be checked with the
device manufacturer before starting the charge operation.
• As radiated electromagnetic wave generated by PDM (Power Delivery Module) at normal charge
operation may affect medical electric devices, a technician using a medical electric device such as
implantable cardiac pacemaker or an implantable cardioverter defibrillator must not approach motor
room [PDM (Power Delivery Module)] at the hood-opened condition during normal charge operation.
PRECAUTION AT TELEMATICS SYSTEM OPERATION
WARNING:
• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),
avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-
rior/exterior antenna.
• The electromagnetic wave of TCU might affect the function of the implantable cardiac pacemaker or
the implantable cardioverter defibrillator (ICD), when using the service, etc.
• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-
able cardioverter defibrillator (ICD), the electromagnetic wave of TCU might affect the function of the
device. The possible effects on the devices must be checked with the device manufacturer before
TCU use.
PRECAUTION AT INTELLIGENT KEY SYSTEM OPERATION
WARNING:
• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),
avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-
rior/exterior antenna.
• The electromagnetic wave of Intelligent Key might affect the function of the implantable cardiac
pacemaker or the implantable cardioverter defibrillator (ICD), at door operation, at each request
switch operation, or at engine starting.
• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-
able cardioverter defibrillator (ICD), the electromagnetic wave of Intelligent Key might affect the
function of the device. The possible effects on the devices must be checked with the device manu-
facturer before Intelligent Key use.
Point to Be Checked Before Starting Maintenance Work
INFOID:0000000010120306
The high voltage system may starts automatically. It is required to check that the timer air conditioner
and timer charge (during EVSE connection) are not set before starting maintenance work.
NOTE:
If the timer air conditioner or timer charge (during EVSE connection) is set, the high voltage system starts
automatically even when the power switch is in OFF state.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010120307
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
PCS-32
< PRECAUTION >
[POWER DISTRIBUTION SYSTEM]
PRECAUTIONS
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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
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 Instruction. SRS wiring harnesses 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 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 three minutes before performing any service.

Component
Description
1.
Electric shift sensor
Electric shift sensor transmits shift signals to VCM. VCM then transmits P position signal and P/N
position signal to BCM.
Refer to
TM-32, "Component Parts Location"
for detailed installation location.
2.
BCM
• BCM controls power distribution system.
• BCM judges power supply position by power switch (push switch) and vehicle condition
• BCM checks the power supply position internally.
Refer to
BCS-5, "BODY CONTROL SYSTEM : Component Parts Location"
location.
3.
Power switch
Refer to
.
4.
IPDM E/R
• IPDM E/R detects power switch (push switch) status, and transmits power switch (push switch)
status signal (CAN) to BCM.
• IPDM E/R receives ignition relay-1 control signal and power switch ON signal (CAN) from BCM,
and controls ignition relay-1.
Refer to
PCS-6, "Component Parts Location"
for detailed installation location.
5.
Stop lamp switch
Stop lamp switch detects that brake pedal is depressed, and transmits the signal to BCM.
Refer to
BRC-10, "Component Parts Location"
for detailed installation location.
6.
Accessory relay
• Accessory relay is controlled by BCM.
• Accessory relay supplies the accessory power supply or the power switch ACC signal to each
ECU when power switch is turned to ACC or ON.
• BCM compares status of accessory relay control signal, and power supply position judged by
BCM.
7.
Ignition relay-2
• Ignition relay-2 is controlled by BCM.
• Ignition relay-2 supplies the power switch ON power supply or the power switch ON signal to each
ECU when power switch is turned ON.
• BCM compares status of ignition relay-2 control signal and power supply position judged by BCM.
