Before I can offer much assistance we will need to elaborate on some details in your post. Currently I assume that the only modification you are making to the LIN Master Send Full Frame and Receive.vi is to change the outgoing isRemote value:

The manual shows that a value of 17 is undefined on page 10-87:

I would like to better interpret your error code to help guide you so some clarification is needed. Are those the values of an error frame or an actual error code? Are they in hexidecimal? Can you attach a screenshot with more detail?

If you set IsRemote 17, then only header frame is sent with no data. If you set IsRemote 18 and select Self Reception, then full frame is sent. But if you do not select Self Reception, no data will be received.
