INFINITI QX60 HYBRID 2017 Dismantling Guide

Powering Down the High-Voltage System
The
high-voltage system can be shut down with any 1 of the following procedures:• Turn OFF the ignition switch and disconnect the 12-volt battery. Refer to Primary Procedure
(DG–21) .
•

Remove the underhood 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–24) .
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. 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. Verify that the READY indicator is off
and then continue to the next steps to open the hood for
12-volt battery negative cable access.
If the READY indicator 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. AAYIA0191ZZ

5. Pull release handle (1) and pull up release lever (2) to open hood.
6.
Remove traction motor inverter cover (1) .
7. Disconnect negative (-) battery cable and cover it with insulated tape.
8. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the battery cable has been disconnected.
9. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–39). AAYIA0272ZZ

NO
TE:
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 not
operate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Release clips (A) and remove fuse box cover (1) . : Vehicle front
3.

Remove IGCT RLY fuse (F/L V IGCT RLY 50A) .
4. If you cannot identify the correct fuse, remove all the fuses. 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. AAYIA0272ZZ

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).
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 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

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.
If the READY indicator does not turn off, continue to
step 4.
4. If possible, keep the Infiniti Intelligent Key at least 5 meters (16 feet) away from the vehicle (except to
open the liftgate as noted below) .
5. Open the liftgate using any of the following: a. liftgate switch on the lower LH side of theinstrument panel. AAYIA0191ZZ

3-4.2 Cutting the Vehicle Body
• 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–20)], 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–29

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS. However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down.
1. Roof-mounted curtain side-
impact and rollover supplemental
air bag inflators 2. Air bag control unit (ACU) 3. Supplemental front-impact air
bag modules
4. Pressure sensors (driver’s side
