The HV disconnect (Figure D-92) is a manual plug that interrupts the traction battery
current path. It is useful for service personnel and emergency rescue teams when an HV
system power down is required. A one hundred (100) amp fuse is housed inside the HV
disconnect.

D.8.2 Electrical Distribution and Electronic Control Cost Impact
The electrical distribution and electronic control system contains both low and high
voltage wiring and controls subsystems for the entire vehicle. For this analysis, when
new HEV devices were added to the vehicle, which drove the need for additional wiring
and/or controls, the cost of the wiring and/or controls was captured in the added device
subsystem or system as opposed to grouping together in a wiring and controls system. The
same methodology held true for the deletion of conventional devices.
Therefore, the only direct manufacturing costs captured in the electrical distribution and
electronic controls system are for the high voltage wire harness found in the Traction and
High Voltage Power Distribution Subsystem. As shown in Table D-12, the net
incremental, direct manufacturing cost impact of the adding the high voltage wire harness
is $201.50. Additional details on the high voltage wire harness can be found in Section
H, Appendix A.
