High Voltage System Shut-Down Procedure
High Voltage System Shut-Down Procedure
Shut down the high voltage system according to vehicle damage level. Any of the following procedures can shut down the high voltage system. The first response operation should be done after shutting down the high voltage system.
If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken or cracked, appropriate PPE must be used and the Li-ion battery and high voltage components must not be touched.
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.
Refer to the above chart to determine which shut-down procedure should be used according to the vehicle damage.
Procedure A: Turning OFF the Ignition Switch
1. Check the READY indicator (1) 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 (2) once to turn OFF the high voltage system. Then verify whether the READY indicator (1) is off. If the READY indicator does not turn off, either of the below methods can shut off the high voltage system:
a. When the trunk can be opened, Procedure B or Procedure C.
b. When the trunk cannot be opened, Procedure D.
4. If possible, keep the INFINITI "lntelligent Key" at least 5 meters (16 feet) away from the vehicle.
5. Wait ten (10) minutes for complete discharge of the high voltage condenser after the ignition switch has been turned OFF.
6. Perform the first response action.
Procedure B: Disconnecting the 12V Battery Negative (-) Cable 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. Open the trunk (1). The trunk can be opened with the push-button switch on the lower LH side of the instrument panel or with the mechanical key (2) housed inside the INFINITI Intelligent Key.
2. Open service access cover-l (3).
3. Disconnect negative (-) battery cable (4) and cover it with insulated tape.
4. Wait ten (10) minutes for complete discharge of the high voltage condenser after the battery cable has been disconnected.
5. Perform the first response action.
Procedure C: Removing the Service Plug
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. Open the trunk (1). The trunk can be opened with the push button switch on the lower LH side of the instrument panel or with the mechanical key (2) housed inside the INFINITI Intelligent Key.
2. Open service access cover 1 (3).
3. Disconnect negative (-) battery cable (4) and cover it with insulated tape.
4. Open service access cover 2 (5).
5. Remove the service plug (6) by pressing the locking tab (a) and rotating the handle (b) fully outward (c). Using the handle, pull the service plug (d) completely out of its socket.
6. Wait ten (10) minutes for complete discharge of the high voltage condenser after the service plug has been removed.
7. Perform the first response action.
Procedure D: Removing Fusible Link from Engine Compartment Fuse Box
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 not operate.
1. If possible, push ignition switch OFF.
2. Pull release handle (1) to open the hood.
3. Remove fuse box cover (2).
4. Remove fusible link (3).
5. If you cannot identify the fusible link (3), remove all fuses and fusible links in the fuse box.
6. Wait ten (10) minutes for complete discharge of the high voltage condenser after the fuses are pulled.
7. Perform the first response action.
