7-6-1 Diagnostic Procedure Summary
7-6-1-1 Purpose of this Sub-Section These software based diagnostics tools are available on Vivid 7:
•Common Service Diagnostic Interface (GSUI)  and
• Vivid 7’s Front-End System Test
To be able to use these Service Tools, the Back-End  Processor must be up and running to some extent. 
If the Back-End Processor doesn’t  starts, it’s not possible to use the software service tools!
