Purpose

Executes the StopDiagnosticSession service. Returns the ECU to normal mode.

Format

diagram

Input

numeric clusterdiag ref in specifies the diagnostic session handle, obtained from Open Diagnostic on CAN FD.vi or Open Diagnostic on IP.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

numeric clusterdiag ref out is a copy of diag ref in. You can wire it to subsequent diagnostic VIs.
booleansuccess? indicates successful receipt of a positive response message for this diagnostic service.
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

This VI disables the current ECU diagnostic mode. A diagnostic session stops only if communication is established with the ECU and a diagnostic session is running. If no diagnostic session is running, the default session is active. StopDiagnosticSession.vi cannot disable the default session. If the ECU has stopped the current diagnostic session, it performs the necessary action to restore its normal operating conditions. Restoring the normal operating conditions of the ECU may include resetting all controlled actuators if they were activated during the diagnostic session being stopped, and resuming all normal ECU algorithms. You should call StopDiagnosticSession.vi before disabling communication with Close Diagnostic.vi, but only if you previously used StartDiagnosticSession.vi.
