Special Tool(s) / General Equipment

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.

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

1.   WARNING: Before beginning any service procedure in this manual, refer to health and safety warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.

   Refer to: High Voltage System Health and Safety Precautions - Overview (100-00 General Information, Description and Operation).
   

1. NOTE: If installing a new module, it is necessary to upload the module configuration information to the scan tool prior to removing the module. This information must be downloaded into the new module after installation.

   Upload the SOBDM configuration to the diagnostic scan tool by following the diagnostic scan tool on-screen instructions.
   

1. With the vehicle in NEUTRAL, position it on a hoist.
   Refer to: Jacking and Lifting - Overview (100-02 Jacking and Lifting, Description and Operation).
   

1. De-energize the high voltage system.
   Refer to: High Voltage System De-energizing (414-03A High Voltage Battery, Mounting and Cables, General Procedures).
   

1. Remove the pushpins, screws and the RH front underbody shield.
   

1. NOTICE: Before disconnecting the high voltage battery electrical connectors, the electrical connectors must be cleaned with a nylon brush and free of debris. Blow any dirt or debris from the electrical connectors with compressed air before disconnecting or component damage may occur.

   NOTICE: High voltage electrical connectors may require unique methods to be disconnected. If not properly disconnected, component damage may occur.

   1. Clean high voltage battery electrical connectors with a nylon brush. Blow any dirt or debris from the electrical connectors with compressed air.
      
   2. Disconnect the high voltage battery electrical connectors from the SOBDM .
      Refer to: High Voltage Connector Disconnect and Connect (414-03A High Voltage Battery, Mounting and Cables, General Procedures).
      
   3. Detach the retainers and position the wire harness aside.
      

1. Clamp the SOBDM coolant hoses. Disconnect the coolant hoses from the SOBDM and position aside.
   Use the General Equipment: Hose Clamp(s)

1. Remove the bolts and the SOBDM .
   Torque: 22 lb.ft (30 Nm)

Installation

1. To install, reverse the removal procedure.
   

1. If a new module is installed, download the SOBDM configuration information from the diagnostic scan tool to the new SOBDM following the diagnostic scan tool on-screen instructions.
   

1. Fill and bleed the electric powertrain cooling system.
   Refer to: Cooling System Filling and Bleeding (303-03D Electric Powertrain Cooling - Hybrid Electric Vehicle (HEV), General Procedures).
