Purpose

Closes a diagnostic session.

Format

diagram

Input

numeric clusterdiag ref in specifies the diagnostic session handle, obtained from Open Diagnostic on CAN FD.vi and wired through subsequent diagnostic VIs. Normally, it is not necessary to manually manipulate the elements of this cluster.
cluster 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.
boolean status is TRUE if an error occurred. This VI is not executed when status is TRUE.
long signed integer 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.
string source identifies the VI where the error occurred.

Output

cluster 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.
boolean status is TRUE if an error occurred.
long signed integer 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.
string source identifies the VI where the error occurred.

Description

The diagnostic session specified by diag ref in is closed, and you can no longer use it for communication to an ECU. Note that this command does not communicate the closing to the ECU before terminating; if this is necessary, you must manually do so (for example, by calling StopDiagnosticSession.vi) before calling Close Diagnostic.vi.
