Removal and Installation
WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to
depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its
components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage
components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious
personal injury or death.
1. Depower the High Voltage Traction Battery (HVTB). For additional information, refer to Hybrid Drive Systems.
2. Disconnect the 12-volt battery. For additional information, refer to Battery.
3. Remove the degas bottle. For additional information, refer to Cooling System.
4. Disconnect the 2 female pin-type retainers from the DC/DC converter bracket.
5. NOTE: Press the locking clip to release the connector.
Disconnect the DC/DC converter high voltage connector.
6. Clamp the Motor Electronics Cooling System (MECS) hoses to prevent coolant from leaking from the hoses during the repair.
7. Loosen the hose clamps and remove the MECS hoses from the DC/DC converter.
8. WARNING: Always tighten the DC/DC converter low-voltage battery cable fasteners to specification. Loose connections may result in
electrical arcing, which increases both the risk of fires and serious personal injury.
Remove the 2 DC/DC converter low voltage battery cable nuts and remove the low voltage battery cables.
