I had the same problem. I've even passed CA emissions but ODB2 data fail to read. The shop guy even said I had to drive 10K miles before the ODB2 data could be read.
Specialized ECU Repair video on youtube really saved the day:
It reads fine now. Try it.

Some have only had luck reading codes with the engine running. Also try cleaning the OBD socket with some spray electronic/electric motor cleaner. If the above doesn't help pull the socket and check the pin wires.
