Pull back your passanger side carpet to reveal the ECU on the floor. Watch the LED as it flashes. It will flash x times quickly and then pause for a longer period of time, then start flashing x times again. Count how many times it flashes quickly, then jot that number down. Do it a couple times over, just to make sure it's the same code and not another (If you're blowing more than one code, it will flash all the codes, then stop, and start from the beginning).
Take those numbers you took down and compare them to a ECU diag chart. Search on
Google for honda ecu codes or something like to find the info on the codes.
Hope that helps! Let me know.
