Generally the codes are only blinked out if the check-engine light (CEL) is on.

The car is actually a Mitsubishi Mirage rebadged as an Eagle Summit, not a Honda. I was able to retrieve the trouble-codes with a voltmeter. Unfortunately the codes aren't concise enough and I still need to diagnose by hand (ugh!)

I used California98Civic's post as a rough guide and found it helpful.
