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.
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 performs the UDS service WriteDataByIdentifier and writes RecordValues (data
values) to the ECU. data in identifies the data. The vehicle manufacturer must ensure the
ECU conditions are met when performing this service. Typical use cases are clearing
nonvolatile memory, resetting learned values, setting option content, setting the Vehicle
Identification Number, or changing calibration values.
