10. Wait 5 minutes after the service disconnect has been removed before continuing service. This allows any residual voltage in the high-
voltage system to dissipate.
11. To repower the system, reverse the depowering procedure.
DC/DC Converter
The DC/DC converter is an air-cooled component that converts high-voltage DC power to low-voltage DC power. It is part of the high-voltage
battery pack and maintains an electrical isolation between the 2 DC power systems. This system converts the high-voltage (approximately 300
volts) to low-voltage (12 volts) that provides power to the vehicle low-voltage battery systems. The PCM controls the operation of the DC/DC
converter through an enabled input from the PCM to the DC/DC converter.
Auxiliary Power Point — 12V
WARNING:
The nominal high-voltage traction battery (HVTB) voltage is 300 volts DC.
WARNING:
The high-voltage traction battery (HVTB) and charging system contains high-voltage components and wiring. High-voltage cables
and wiring are orange in color.
