Is this an OBDII reader?   Paul T.

There may be some codes the OBDII reader won't read, and I don't believe that an OBD reader will give you access to airbag or anti-lock functions. The Testbook is eesentially unobtainable to us mortals, but for the low, low sum of approx $10K, you can buy the home-use version, the Rovacom, or autologic testers.
