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

Overview
NOTICE:
Do not use leaded fuel in a vehicle equipped with a
catalytic converter. In a vehicle that is continually misfueled, the
lead in the fuel will be deposited in the catalytic converter and
completely blanket the catalyst. Lead reacts with platinum to "poison"
the catalyst...
