Location Description
DC/DC
Converter Cargo
area floor
(mounted right of
high-voltage battery) 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 Cargo area floor
(inside storage bin
behind access door) This is used to disable the high-voltage system.
High-Voltage
Battery Cargo area floor
(under 3rd row seat-
ing floor trim) The high-voltage battery stores and outputs DC
power (Maximum voltage 144V) needed to pro-
pel the vehicle.
Traction Motor Engine compartment
(built-into the trans-
mission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter
Engine compartment
(front driver 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.
12-Volt Battery
Front of the vehicle
on the left side of the
engine compartmentA lead-acid battery that supplies power to the
low voltage devices.

compartmentOrange-colored power cables carry high DC
voltage between each of the high-voltage com-
ponents.

5. Remove traction motor inverter cover (1) .
6.
Disconnect negative (-) battery cable and cover it with
insulated tape.
7. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the fuse panel and battery cable have been disconnected.
8. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–39).

Procedure 2 (Remove Service Plug) • Do not remove the service plug without always wearing appropriate Personal
Protective
Equipment (PPE) to help protect the dismantler from serious injury or death
by electrical shock.
• Immediately cover the service plug socket with insulated tape. The high-voltage
battery
retains high-voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket. To avoid unintended reinstallation and risk of electrical shock and severe personal
injury
or death, the dismantler should carry the service plug on his/her person while work
is in progress.
NOTE: Before disconnecting the 12-volt battery terminal, if necessary, lower the windows,
adjust the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate. AAYIA0273ZZ
