Procedure Hierarchy

Each procedure in this service information is presented as all inclusive, and by performing all of the steps listed, the technician can complete the intended service. Some of the steps of one procedure reference to other procedures, which are also all inclusive. This creates a hierarchy of top-level procedures with subordinate procedures, and is used to shorten lengthy processes into groupings of simpler and easy to remember tasks.

A side effect of the hierarchy is that the technician must actively recognize when certain steps in a subordinate procedure have already been performed  , either in the top-level procedure or in another subordinate procedure, and are therefore unnecessary to repeat  . The step duplication caused by the hierarchy is considered in the correction codes and flat rate times of the top-level procedures.
