NOTE:
Components with white number in black background are high voltage components.No. Component
LocationDescription
a Charge
port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so
equipped) .
b High voltage
cables Under hood and
undercarriage Orange-colored power cables carry high volt-
age current between each of the high voltage
components.
c Traction Motor Under hood Converts three-phase AC power to drive
power (torque) which propels the vehicle.
Inverter Under hood Converts the DC power stored in the Li-ion
battery to three-phase AC power and controls
motor torque (revolution) by regulating the
motor current.
Electric air condi-
tioner compressor Under hood
Air conditioner compressor
Power Distribution
Module (PDM)
• On Board Charger
• DC/DC Converter
• High voltage junction box (J/B) Under hood
The PDM includes an On Board Charger, DC/DC
converter and high voltage junction box (J/B) .
The On Board Charger converts single-phase AC
power from a home power outlet to DC power and
increases the voltage in order to charge the Li-ion
battery.
The DC/DC converter reduces the voltage of the Li-ion
battery to provide power to the 12V battery in order to
operate the vehicle’s electric components (headlights,
audio system, etc.) .
The J/B provides electric power from the Li-ion battery
to all high voltage parts of the vehicle.
d 12V Battery Under hood A lead-acid battery that supplies power to the low
voltage devices.
e Cabin heater Interior (This unit is
installed behind the
instrument panel) This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
f Li-ion (Lithium ion)
battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
g High voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the high volt-
age electrical system.
h Brake power supply
backup unit Cargo area (This unit
is installed behind a
trim panel to prevent
access) Power supply backup unit for the brake system. It
supplies power to the brake system if a malfunc-
tion occurs in the 12V battery.

3. Roadside Assistance Response Steps
• NEVER assume the LEAF is shut OFF simply because it is quiet.
• If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the high
voltage system should be shut down by first responders while following the procedures in
the First Responders Guide and while wearing appropriate Personal Protective
Equipment (PPE) .
• If the READY indicator or charging indicator are ON, the high voltage system is
active.
• If possible, be sure to verify that the READY indicator on the instrument cluster
is
OFF and the high voltage system is stopped.
• Some of the under hood parts get hot and may cause serious burns. Use caution when working on or around these parts.
3-1 Indications the High Voltage System is ON 1. If the READY indicator is ON, the high voltage system is active.
2.
The high voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12V battery terminal, if necessary, lower the windows, unlock the doors, and open
the rear hatch as required. Once 12V battery is disconnected, power controls will not operate.
3-2 Vehicle Immobilization and Stabilization
If possible, immobilize the vehicle by turning the 12V system OFF and stabilize it with a wheel chock(s) .
Stabilize the vehicle with wooden blocks or by removing air from the tires. • Do not stabilize the vehicle with wooden blocks under the Li-ion battery.
•
To avoid electrical shock, do not put wooden blocks or wheel chock(s) under the high
voltage components and harnesses as shown following. AAYIA0155ZZ
