BYTE BIT VALUE DESCRIPTION
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.
