Ford Escape: High Voltage Battery, Mounting and Cables / Removal and Installation - Battery Energy Control Module (BECM) - Hybrid Electric Vehicle (HEV)

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.

NOTICE: BECM (battery energy control module) should be carefully handled, if dropped must be scrapped.

NOTE: All gaskets and sealing surfaces must be clean and free of all foreign matter prior to assembly.

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.

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