9.4.3.1 Programming Setup (Pre-Utility File) Process. 
The following steps (Table 229) are performed prior
to the execution of one or multiple utility file(s) to make sure that the GMLAN network (including all GMLAN
sub-networks) transitions to the programming state (vehicle oriented step). In addition the Pre-Utility File
process determines the CAN communication parameters (setup of the diagnostic configuration matrix). All
steps of the pre-utility file process are functionally addressed to all nodes on the GMLAN sub-networks (except
certain steps included in the verification process) and performed automatically.
