Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures:• Turn OFF the power switch and disconnect the 12V battery. Refer to
Primary Procedure (DG–21).
• Disconnect the underhood fuse panel terminal connector for the high voltage control system and disconnect the 12V battery. Refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel) (DG–24)
.
• Remove the service plug and disconnect the 12V battery. Refer to
Alternate Procedure 2
(Remove Service Plug) (DG–27)
.
Primary Procedure
NOTE:
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V battery is disconnected,

Alternate 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 Li-ion 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 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V battery is disconnected,
power controls will not operate.
1. If possible, check the READY
indicator status in the instrument cluster. If it is on, the high
voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high voltage system. Then verify whether the READY indicator
is off.
