16. Remove the bus bar mounting nut which connects the current

sensor and left front module stack  .

DANGER:

•

 There is the danger of electric shock caused by

contact with the terminals. Be sure to wear insulated pro-

tective gear and use insulated tools.

•

Because of the danger of electric shock, be sure to

close the bus bar cover after removing the bus bar.

17. Remove the service plug switch bracket   mounting bolts  .

WARNING:

To prevent electric shock, wear insulated protective

gear and use insulated tools.

18. Invert the service plug switch bracket and remove the high-volt-

age harness mounting bolt  , current sensor mounting bolt  ,
and the connector  , then remove the service plug switch
bracket .

DANGER:

•

 There is the danger of electric shock caused by

contact with the terminals. Be sure to wear insulated pro-

tective gear and use insulated tools.

•

Because there is a risk of electric shock, immediately protect the terminals of the discon-

nected high-voltage harness connector (high-voltage terminals) with insulating tape so that they

are not exposed.

19. Remove the mounting nuts  , then remove high-voltage harness   and  .

ASSEMBLY

Note the following items, and disassembly in the reverse order of disassembly.

DANGER:

•

 There is the danger of electric shock caused by contact with the terminals. Be sure to wear

insulated protective gear and use insulated tools.

•

Because there is a danger of electric shock and fire, never allow bus bar to contact a wrong ter-

minal.

- If bus bar contacts a wrong terminal, the circuit becomes energized and a short may occur.

- Always keep the bus bar cover closed until immediately before the installation of bus bar.

- Since the correct installation position for the bus bar connected to both front module stacks is com-

monly-confused with the wrong position  , install the bus bar to the correct position   with extreme

caution.

WARNING:

Install the Li-ion battery controller immediately before installing the battery pack upper case. Refer to

EVB-201, "LI-ION BATTERY CONTROLLER : Removal and Installation"

.

CAUTION:

• Perform the “LI-ION BATTERY JUNCTION BOX DATA CLEAR” when battery junction box is replaced.

Refer to 

EVC-135, "Work Procedure"

.

• Be sure to reinstall the high voltage harness clips in their original positions. If a clip is damaged,

replace it with a new clip before installing.

• Check the following items after installing battery pack: Refer to 

EVB-256, "Inspection"

.
