•

Remove the fuses for the high voltage control system and disconnect the 12V battery. Refer to
3-3.5 Alternate Procedure 1 (Remove Fuses) (DG–21) .
•

Remove the service plug and disconnect the 12V battery. Refer to 3-3.6 Alternate Procedure 2
(Remove

Service Plug) (DG–24) .
3-4.4

Primary Procedure
1. Check the READY indicator status. If it is ON, the high voltage system is active.
2.

Place the selector lever in the Park (P) position.
3. Press the power switch once to turn OFF the high voltage system. Then verify whether the READY indicator is OFF and continue to the next steps to
open

the hood for 12V battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (DG–21)
4. If possible, keep the Nissan Intelligent Key® at least 5 meters
(16 feet) away from the vehicle. AAYIA0155ZZ

5. Open the hood.
6.
Disconnect the negative (-) 12V battery cable (1) .
Insulate the negative (-) battery cable terminal with
insulated tape.
NOTE: : Arrow in illustration depicts vehicle front
direction.
7. Wait

at least ten (10) minutes for complete discharge of the high voltage capacitor after
the power switch has been turned OFF.
8. Perform the dismantling operation.

insulated tape.
NOTE: : Arrow in illustration depicts vehicle front
direction.
7. Wait

at least ten (10) minutes for complete discharge of the high voltage capacitor after
the fuses are pulled.
8. Perform the dismantling operation. To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or

death, the dismantler should carry the fuses on his/her person and cover the fuse box
with insulated tape. 20A VCM (Yellow)

3-5 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, NEVER touch the high voltage parts or the insides of the
exposed orange-colored high voltage cables to avoid severe personal injury or death.
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 at least ten (10) minutes have passed since the dismantler shut down the high voltage system (refer to
3-3 High Voltage System Shut-Down Procedures (DG–16)) , 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.
DG–26

12. If necessary, connect the vehicle to a charging station or EVSE (Electric Vehicle Supply
Equipment) to charge the Li-ion battery. The vehicle cannot be driven unless the Li-ion battery is
charged.
NOTE:
If it is not possible to turn the LEAF system ON by following this procedure, contact a
NISSAN certified LEAF dealer immediately.
4-2 P (Park) Position Release Procedure
If you need to release the vehicle from the P (Park) position, proceed as follows. When power switch is
turned OFF or 12V battery is low, LEAF automatically shifts to P position.
NOTE: This procedure requires two (2) people.
1. To start the EV system with a booster battery, refer to 4. Jump Starting (DG–31).
2.

Turn power switch ON by pushing the power switch 2 times without pressing brake pedal.
3. Confirm parking brake is applied.
4. Close all doors and press and hold the brake pedal.
5. Place the selector lever in the N (Neutral) position.
6. Remove the following 2 fuses:
• F/L 40A PBW MTR (under hood fuse and relay box)
