3-3 High Voltage System Shut-Down Procedures

Once the high voltage battery is properly discharged, any of the following procedures can shut down and
isolate the high voltage system. The dismantling operation can only begin after shutting down the high
voltage system. If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken or
cracked, appropriate Personal Protective Equipment (PPE) must always be used and the Li-ion battery and
high voltage components must not be touched.

Failure to properly shut down the high voltage system before the dismantling

procedures are performed will result in serious injury or death from electrical shock. To
prevent serious injury or death, DO NOT touch high voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE).

When contact with high voltage components or high voltage harnesses is unavoidable,

or when there is risk of such contact, you must always wear appropriate PPE.

If the charge connector is connected to the vehicle, remove it. Refer to

3-3.1 Removing

the Charge Connector

.

The vehicle contains parts that contain powerful magnets. If a person who is wearing

a pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.

• Be sure to verify that the READY

indicator is off and the high voltage system is

stopped.

• After the high voltage system is shut down, please wait at least ten (10) minutes for

complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.

• After shutting down the high voltage system and removing the 12V battery negative (-)

terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though the
12V battery negative (-) is disconnected, the Supplemental Restraint System (SRS) air bag
maintains voltage at least three (3) minutes. During this time, there is a possibility of
sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.

• Always shut down the high voltage system before disconnecting the 12V battery. Not doing

so may result in serious injury or death from electrical shock.

• The 12V system will remain active even after the 12V battery negative (-) terminal is

removed while the high voltage system is active. The high voltage system is active during
any of the following conditions:

– charging indicator is turned ON

– READY indicator is turned ON
Refer to

1-1.2 Interior Component Location

for location of these indicators. This is because

DC/DC converter will not shut down and power will be supplied to the 12V system and
high voltage system continuously.
