What repairman54 offers for a solution is only for the OBD port. But you also asked about the instrument panel lights. If the 2 questions are related, then the OBD 2 doesn't have a code for instrument panel lights. I'm guessing you already know that. But just in case you didn't. If you have only some instrument panel lights out, then it's most likely the bulbs or the sockets. Sockets rarely go bad. So I would have to say that it's the bulbs.
