Transfer Case Principles introduces learners to the main types of vehicle architectures, concepts on how a transfer case functions within a four-wheel vehicle, and how human interactions can influence how a transfer case operates.

Learning Objectives
  • Differentiate the various types of vehicle architectures.
  • Recognize mechanical components with the drivetrain of a four-wheel drive vehicle.
  • Recall electrical hardware and software used within a four-wheel drive vehicle.
  • Outline the supporting physics that allow four-wheel drive vehicles to operate.
  • Name the different transfer case subsystems.
  • Define driver-selectable modes and how an operator can directly or indirectly communicate with the transfer case.
