Oh..
Well , I guess what I mean is ...if you used the built-in led/sw , you will get the codes from the DM..which would be a TN signal for a code 11.
But......
My question stems from the fact that you said you has built the code reader tool and used that..if that is the case , the tool is to go to the other modules on the Box [ pins 8 or 14] and if that is what you have done , then a code 11 is not a TN sig code.
Just making sure you realize this so you are not going in the wrong direction.

Here are the codes that correspond to both the Tool you made and the built-in led/sw ones ..as you can see , that is why I ask where you got that code from..
