You've got a civic CX? Nice man, Do you know what code might be coming up?. Like have you tried counting the long flashes. One long flash is 10 one short rapid flash is a single digit such as 1, 2, or 3. etc... So like If you see the light flashing long thats 10 with two short flashes 2. That's code 12 just as an example.
