Diagnostic Procedures
This section contains a set of diagnostic procedures that may be referenced directly or used in
conjunction with the Operational Problems first level diagnosis flow charts.
Each procedure starts with a description of the symptoms of the error class, followed by diagnostic
actions that allow the actual fault to be pinpointed more accurately. After this has been achieved, it
should be possible for the user to attempt to correct the fault.
