2-2 High Voltage-Related and 12-Volt-Related Component Locations and Descriptions
NOTE:Components with white number in black background are high voltage components.
No. Component Location Description Traction Motor Inverter Engine compartment
(rear passenger side) Converts the DC power stored in the high
voltage battery to three-phase AC power and
controls motor torque (revolution) by regulating
the motor current. The inverter has a built in
high voltage capacitor.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.

No. Component Location Description High voltage Battery
Trunk area (behind
rear seat back) The high voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DCConverter Trunk area (mounted
to top of high voltagebattery) The DC/DC converter reduces the voltage of
the high voltage battery to provide power to
the 12-volt battery in order to operate the
vehicle’s electric components (headlights,
audio system, etc.) .
Service Plug Trunk area (below
parcel shelf; behind
access door in trimpanel) This is used to disable the high voltage system.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltagecomponents.

3-2 Personal Protective Equipment (PPE) and Insulated Tools
3-2.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-2.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage.• Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-2.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-3 Discharge Procedures
DANGER
Do not perform this procedure if the battery is damaged. If you are unsure of battery
damage, use extreme caution and wear appropriate Personal Protective Equipment (PPE) .
High voltage battery discharging must take place before dismantling. Sufficient discharging can be achieved
by following these steps. 1. Place the shift selector into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely immobilized.
4. Fasten the driver seat belt and close the driver door.
5. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY
indicator in instrument cluster turns ON.a. If the engine starts, leave the engine on until the idling stops.
b. If the engine does NOT start, move on to next step.
6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (B) using mechanical key as shown in the illustration.
8. Push the shift selector button (C) and move the shift selector to the Neutral (N) position (D) while holding
down the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise high voltage battery will
start to be charged.

SRS Air Bag System Components Location
The SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS However, the vehicle can be cut (except inflators) under the following conditions:• The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high voltage system has been shut down.
1. Crash zone sensor (located
underhood near hood latch) 2. Supplemental front air bag
modules (Infiniti Advanced
Air Bags)3. Front seat-mounted side-
impact supplemental air bags
4. Roof-mounted curtain side-
impact supplemental air bags 5. Roof-mounted curtain side-
impact supplemental air baginflators6. C-pillar satellite sensors
(LH shown, RH similar)
7. Seat belt buckle pretensioners 8. Seat belts with pretensioners 9. B-pillar satellite sensors
10. Air bag control unit (ACU) 11. Front door satellite sensors (LH shown, RH similar)

32. Remove the mounting bolts (A) of bracket (RH) onvehicle side.
DANGER
Touching high voltage components without wearing
appropriate Personal Protective Equipment (PPE) will
cause electrocution.
33. Place a piece of plywood (A) in the trunk room as shown in the figure. Lift the battery pack in the direction (1) shown by arrow and slide (2) the cardboard (B) to location (C) to position it under
the battery pack.
DANGER
Touching high voltage components without wearing appropriate Personal Protective
Equipment (PPE) will cause electrocution.
34. Pull out battery pack (1) together with the cardboard (A) in the rear of vehicle.
DANGER
Touching high voltage components without wearing
appropriate Personal Protective Equipment (PPE) will
cause electrocution.
Battery pack is in unstable condition. Never allow it to fall.
