fuses INFINITI Q70 HYBRID 2018 Dismantling Guide

•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 thevehicle.
• Be sure to check the READY indicator (1) in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for approximately ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not
operate any vehicle functions.
• Remove the 12-volt battery negative (-) terminal and wait for three (3) minutes to discharge the air bag capacitor. Even though the 12-volt battery negative (-) is
disconnected, the Supplemental Restraint System (SRS) air bag maintains voltage for
three (3) minutes. There is a possibility of sudden SRS air bag inflation due to
harness short circuit or damage and it may cause serious injuries.
• The 12V system will remain active even after the 12-volt battery negative (-) terminal is removed while the high voltage system is active. This is because the DC/DC converter
will not shut down and power will be supplied to the 12V system and high voltage
system continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.
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 12-volt battery. Refer to
Primary Procedure
(DG–21)
.
• Remove the fuse for the high voltage control system and disconnect the 12-volt battery. Refer to
Alternate Procedure 1 (Remove Fuses) (DG–23).
• Remove the service plug and disconnect the 12-volt battery. Refer to
Alternate Procedure 2
(Remove Service Plug) (DG–25)
.
DG–20

Primary Procedure
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.
1. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, refer to
Alternate Procedure 1 (Remove Fuses)
(DG–23)
4. If possible, keep the Infiniti Intelligent Key at least
5 meters (16 feet) away from the vehicle (except as
noted below) .
5. Open the trunk using any of the following: a. push-button switch (C) on the lower LH side of the instrument panel.
b. trunk button (D) on the Infiniti Intelligent Key [press for longer than one (1) second].
c. trunk open request switch (E) (located above license plate)*.
d. with the mechanical key (F) housed inside the Infiniti Intelligent Key.
Method Shift Selector Position Ignition Switch Status
a P or N Any
b P OFF
c* Any Any
d Any Any
* You must have the Infiniti Intelligent Key within approximately 1 meter (3 feet) range of trunk request switch
to use the trunk open request switch function.

Alternate Procedure 1 (Remove Fuses)
NOTE:Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will notoperate.
1. Pull release handle (A) to open the hood.
2. Remove fuse box cover (B) .
3. Remove 80A fuse (C) (black) .
4. If you cannot identify the fuse (C) , remove all fuses in the fuse box.
To avoid unintended reinstallation and risk of electrical shock and severe personal
injury or death, the dismantler should carry the fuse or fuses on his/her person and cover
the fuse box with insulated tape.

10. Cover the service plug socket with insulated tape.
11. Wait approximately ten (10) minutes for complete discharge of the high voltage capacitor afterthe service plug has been removed.
12. Perform the dismantling operation. Refer to
6. Dismantling Information (DG–38).
3-4.2 Cutting the Vehicle Body
DANGER
•Do not cut into high-voltage related areas to avoid severe personal injury or death.
•
Do not cut into the high-voltage battery to avoid severe personal injury or death.
•
When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components.
To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death, the dismantler should carry the fuses or service plug on his/her person while work
is in progress.
Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe personal injury or death.
If approximately (10) minutes have passed since the dismantler shut down the high voltage system [refer
to
3-4.1 High Voltage System Shut-Down Procedure (DG–19)], then the dismantler can cut the vehicle
except for the high voltage battery.
DO NOT cut the high voltage battery due to possible electrocution risk and electrolyte solution leakage. DG–28
