Error -301007 Using the ECU Measurement and Calibration Toolkit

Primary Software: Other NI Software>>ECU Measurement and Calibration Toolkit
Primary Software Version: 1.0
Primary Software Fixed Version: N/A
Secondary Software: Other NI Software>>ECU Measurement and Calibration Toolkit

Problem:
I am getting the following error when using the ECU Measurement and Calibration Toolkit. What is the cause of this error and what can I do to resolve this error?



Solution:
In the A2L file that is being used, there is usually an A2ML section at the top. This section is used to declare some parameters that inform the toolkit how to communicate with the ECU. An example parameter would be the baudrate to use.

An example of what this section looks like is below:

Note: This information is from the Example A2L file that is shipped with the toolkit. You can find it the following location: C:\Program Files\National Instruments\LabVIEW 8.6\examples\ECUMC\CCPECU.a2l

The specific struct that is required for the toolkit is the TP_BLOB.  This is where the baudrate and other important parameters are defined.

Below are the definitions that are used for the TP_BLOB:

Here is an example of how the baudrate is defined:

If the A2L file does not have this section then the ECU Toolkit won't know what these parameters will be and they will need to be set in the program. Therefore this error is thrown.

You will need to ensure that you set the following parameters for the ECU:

  • CRO Id
  • DTO Id
  • BaudRate
  • StationAddress 

Once, these are set to a known value the error should no longer occur.

If you are not sure if the parameters are valid in the A2L file, you can use the example from the Example Finder within LabVIEW » Hardware Input and Output » CAN » ECU Measurement and Calibration Toolkit » Advanced » Edit some Paramters.vi .

Wtihin the example select Change conn parameters? prior to starting the VI. A dialog box will pop up with the pre-populated parameters from read the A2L file. You can determine if they are valid or not, and if they are invalid you will know to manually set them in the program.
