Removal

  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 system utilizes approximately 450 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.   WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.

    NOTE: Removal steps in this procedure may contain installation details.

    Refer to: High Voltage System Health and Safety Precautions - Overview (100-00 General Information, Description and Operation).
  1. With the vehicle in NEUTRAL, position it on a hoist.
    Refer to: Jacking and Lifting (100-02 Jacking and Lifting, Description and Operation).
