 Autochanger Error Codes
60 FRU Isolation Test Assumes that something has physically failed, 
either electronic or mechanical. A series of 
special low-level tests are executed to select the 
three (or fewer) FRUs which are most likely to 
be at fault. Tests 30, 31, 33, 35, 36, 40, and 50 
are executed as a part of the isolation process.
