You need an OBD-II scantool to reset the Check Engine light. Places like Autozone will read your codes for you but most will not reset the Check Engine light because of liability issues. You need to either purchase a code reader with reset capability or find someone who has one to do it for you.
Even if you reset it you will still fail the test because the emissions monitor testing will not be complete. Once the monitors are complete the check engine light will turn on because the cat is bad. Its a catch 22.
If its just a safety inspection you may be able to get away with resetting the light. You can try disconnecting the battery for about a minute. or you can remove the back-up radio(clock) fuse from the under hood fuse block for about 30 seconds.
If you live in the continental US and your catalytic converter is bad your vehicle is not eligible to be licensed for on road use per Federal Emissions Laws.
The only thing I can think of checking would be the EGR valve, a faulty cat converter or faulty o2 sensor. Converter shouldn't set off check engine light though unless it is clogged causing too much back pressure, most likely EGR Valve.
YOU HAVE A TORQUE CONVERTER PROBLEM. TORQUE CONVERTER CONTROL CIRCUIT MALFUNCTION CODES CAN COME FROM ELECTRICLE TO INTERNAL MALFUNCTION. IF YOU START EXPERIENCING A HARD SHIFT OR FREE SPIN TO HARD SHIFT DON'T BE SURPRISED. TRY CHANGING FLUID. THIS MAY HELP. HONDA WOULD HAVE REPLACED TRANS IF UNDER 105 k FOR FREE. IF YOU HAVE TO REPLACE TRANS. BUY ONE FROM HONDA, 3 YR WARRANTY AND AS CHEAP AS A REBUILT TRANS. HAVE A QUALIFIED PERSON INSTALL, YOU WILL SAVE ABOUT $500 DOING IT THIS WAY. GOOD LUCK
