4	0-7			The Routine in Error field contains the Routine ID of the failing routine. If this
				field contains 00h, no errors were detected during the last execution of a SEND
				DIAGNOSTIC command.
5	0-7			The Execute Count field contains the number of passes attempted before an error
				was detected. If an error is detected on the first pass, this field contains a 1. This
				field is reset each time a new (different) routine is started. For example: if the
				SEND DIAGNOSTIC command Parameter list contained a pass count of 4 for
				Routine 50, and a pass count of 7 for Routine 51, and an error was detected on
				the third attempt to execute Routine 51, this field would contain a 3.
6-11				This field contains the Fault Symptom Codes that indicate the cause of the error.
