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 DIAG-

 

 

 

 

 

 

NOSTIC command.

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.

This field contains the Fault Symptom Codes that indicate the cause of the error.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4-3.19.4 RECEIVE DIAGNOSTIC RESULTS CHECK CONDITION Status

If the initiator does not send a SEND DIAGNOSTIC command first, the command is terminated with GOOD status and the target does not transfer any result data.

All reserved bits must be zero. If these bits are set to one, the command is terminated with CHECK CONDITION status and the sense key is set to ILLEGAL REQUEST.
