Ok, so I decided to hook up an OBD2 reader to my car to see if any codes were present, after reading it displays "U3LLL" and that's all. I deleted the codes and read again, same code reads in. I've searched on Google with 0 results, and the forums have zero results.. just my luck.

What is "U3LLL" code mean on OBD2 reader? I understand the "U" stands for undefined, but the rest, I have no clue.

I got a different OBD2 reader and didn't have any codes, I'm thinking the OBD2 reader I initially used was for the wrong protocol because it was a CAN OBD reader..
