Purpose

Executes the UDS InputOutputControlByIdentifier service. Modifies ECU I/O port behavior. Format

Input

data in defines application-specific data for this service.
diag 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.
ID defines the identifier of the I/O to be manipulated. The values are application specific.
mode defines the I/O control type. The values are application specific. The usual values are:
0:ReturnControlToECU
1:ResetToDefault
2:FreezeCurrentState
3:ShortTermAdjustment
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.
data out returns application-specific data for this service.
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 substitutes a value for an input signal or internal ECU function. It also controls an output (actuator) of an electronic system referenced by the local ID parameter.
