INFINITI M HYBRID 2013 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 the vehicle.
• 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 ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
NOTE:
The high voltage full discharge takes ten (10) minutes, but after five (5) minutes the voltage
has dropped below 60V.
• Remove the 12V battery negative (-) terminal and wait for 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 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 12V 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 12V 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 12V 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 12V battery. Refer to Primary Procedure.
•

Remove the fuse for the high voltage control system and disconnect the 12V battery. Refer to Alter-
nate

Procedure 1 .
•

Remove the service plug and disconnect the 12V battery. Refer to Alternate Procedure 2. 21

Primary Procedure
NO
TE:
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. 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, continue to the next steps to open the trunk for 12V
battery negative cable access.
4. If possible, keep the INFINITI Intelligent Key™ at least 5 meters (16 feet) away from the vehicle (except as noted
below) . AAYIA0062ZZ

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

6. Open the 12V battery service access cover (G) .
7.
Disconnect negative (-) battery cable (H) and cover it with insulated tape.
8. Wait 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. AAYIA0034ZZ

Alternate Procedure 1
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 (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. AAYIA0004GB

5. Open the trunk. The trunk can be opened with the push-button switch (D) on the lower LH side of
the instrument panel or with the mechanical key (E) housed inside the INFINITI Intelligent Key™.
6. Open the 12V battery service access cover (F) .
7. Disconnect negative (-) battery cable (G) and cover it with insulated tape.
8. Wait ten (10) minutes for complete discharge of the high voltage capacitor after the fuse is pulled and battery cable has been disconnected.
9. Perform the dismantling operation. Refer to 6. Dismantling Information. AAYIA0011GB

Alternate Procedure 2
• Do not remove the service plug without always wearing appropriate PPE to help
protect the dismantler from serious injury or death by electrical shock.
• Immediately cover the service plug socket with insulated tape. To avoid electric shock, DO NOT 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. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.

3-3.2

Cutting the Vehicle Body • Do not cut into high voltage related areas to avoid severe personal injury or death.
• Do not cut into the Li-ion battery to avoid severe personal injury or death.
• When removing parts, DO NOT touch the high voltage parts or the insides of the
exposed
orange-colored high voltage cables to avoid severe personal injury or death. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe

personal injury or death.
If ten (10) minutes have passed since the rescuer shut down the high voltage system (refer to 3-3.1 High
V

oltage System Shut-Down Procedure ) , then the dismantler can cut the vehicle except for the Li-ion battery.DO NOT cut the Li-ion battery due to possible electrocution risk and electrolyte solution
leakage.
