No, you cannot use an OBD scan tool. The DRB2 connection you are referring to can be used by a mechanic with the proper tools. You can read the codes by the key method. Turn the key on, then off, then on, then off, and finish with on. The codes will then flash the number of the first digit then it will pause and blink the number of the second digit.
