I tried mine out today, but I think, MAYBE the candi module might be bad.

I tried running trans codes for my work van. Kept getting this.
I scanned 1st without the module between the tech 2 and obd. I did get engine codes, but no trans codes. Then with the candi module in between. Is the candi needed to get the trans codes? I tried getting the tech 2 to test things--wouldn't do it. Am I doing something wrong? And how are you supposed to know what designation to use for the vehicle?
