The following URL, although a VW site, has a good explanation of what OBD-II is, why it exists, and how it is used.

Among its information is that PCM stands for Power Control Module. This is the computer that monitors and controls the Powertrain.

Looking down the list, you will see:

P0602 Control Module Programming Error/Malfunction

This means that there is a problem with the computer. About the only thing you can do yourself is disconnect a battery lead for 15 min, which will reset it. If it comes back, you need professional help.
