Output
diag ref out is a copy of diag ref in. You can wire it to subsequent
diagnostic VIs.
data out returns the ECU memory data.
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.
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.
Description
This VI requests ECU memory data identified by the address and size parameters. The data
out format and definition are vehicle manufacturer specific. data out includes analog input
and output signals, digital input and output signals, internal data, and system status
information if the ECU supports them.
For further details about this service, refer to the ISO 15765-3 standard.
