From my experiences and the documentation I have, Honda put an LED on the
face of the ECU and TCM up to 1991. This LED was activated whenever the
ignition switch was turned to "II".

For 1992 Honda did an across-the-board revision of all their ECUs and of
error-reading procedures. From that point on, you had to jump the Service
Check connector to read codes from lights on the dashboard. Prior to that,
the Service Check connector was only jumped when you were setting base
ignition timing.

I could be wrong on the above, but I can't find evidence of that.
