Purpose

Executes the ECUReset service. Resets the ECU. Format

Input

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.
mode indicates the reset mode:
HexDescription
01PowerOn This value identifies the PowerOn ResetMode, a simulated PowerOn reset that most ECUs perform after the ignition OFF/ON cycle. When the ECU performs the reset, the client (tester) re-establishes communication.
02PowerOnWhileMaintainingCommunication This value identifies the PowerOn ResetMode, a simulated PowerOn reset that most ECUs perform after the ignition OFF/ON cycle. When the ECU performs the reset, the server (ECU) maintains communication with the client (tester).
03–7FReserved
80–FFManufacturerSpecific This range of values is reserved for vehicle manufacturer-specific use.
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.
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 the ECU to perform an ECU reset effectively based on the mode parameter value content. The vehicle manufacturer determines when the positive response message is sent.
