To me it sounds like the RAD is throwing the codes. I believe those are the two mine throw when I run the RAD. One of the things RAD's usually do is interupt the VSS and Torque managment, interupting the signal between the PCM and ECM, hense the No CCD Messages Recieved from PCM. And it always throws the p1693, because you are interupting the signal. You must have them cleared, you can't do it yourself. But everytime you use the RAD that p1693 will come back and stay until it gets cleared again.
