OBJECTIVES
At the end of this training course, you should be able to:
identify the main components of a 2010 electrical architecture.
to explain the main functions and give the characteristics of the
electrical power supplies protection and management module.
to explain the main functions and give the characteristics of the
engine ancillaries ECU.
to explain the main functions and give the characteristics of the
built-in systems interface.
to identify the different networks used on the 2010 electrical
architecture.
to identify the different 2010 electrical architecture power supplies
to explain the future lines of the 2010 electrical architecture.
