Yes, there's options. wire up CONSULT port, and use a consult program. Or CONSULT itself with the proper card. Solder in an led on the ecu, also wire up pin24 IIRC, run it through the dash connector for the check engine light. This way, your check engine light will flash the codes on the dash.
CONSULT programs:NDS, consult-free, and ECUtalk. All will read stored codes and allow you to clear them.
