group of DTC specifies the group of Diagnostic Trouble Codes to be
controlled. The following values have a special meaning, and you can
specify them through a ring control:

0x8000 All body DTCs
0xC000 All network-related DTCs
0xFF00 All DTCs
error in is a cluster that describes error conditions occurring before the VI
executes. If an error has already occurred, the VI returns the value of the
error in cluster to error out.
status is TRUE if an error occurred. This VI is not executed when
status is TRUE.
code is the error code number identifying an error. A value of 0
means success. A negative value means error: the VI did not
execute the intended operation. A positive value means warning:
the VI executed intended operation, but an informational warning
is returned. For a description of the code, wire the error cluster to
a LabVIEW error-handling VI, such as the Simple Error
Handler.
source identifies the VI where the error occurred.
Output
diag ref out is a copy of diag ref in. You can wire it to subsequent
diagnostic VIs.
success? indicates successful receipt of a positive response message for
this diagnostic service.
error out describes error conditions. If the error in cluster indicated an
error, the error out cluster contains the same information. Otherwise,
error out describes the error status of this VI.
status is TRUE if an error occurred.
