Fair point. My 1984-1995 Civic Chilton's manual indicates
there is not a fast and slow ECU light code sequence for any
of these Civic years. In particular, for years 1988-1995, my
Chilton's manual says:
---
For all the conditions listed, the PGM-FI warning light on
the dashboard must be on (comes on and stays on). This
indicates a problem in the electrical portion of the fuel
injection system. At that time, check the LED display
(self-diagnosis system) in the ECU/ECM.
There is only one LED display. The LED will blink
consecutively to indicate the trouble code. The ECU/ECM is
located beneath the access panel, under the carpet on the
passengers side of the vehicle.
Sometimes the dash warning light and/or ECU/ECM LED will
come on, indicating a system problem, when, in fact, there
is only a bad or intermittent electrical connection.
... blah blah...
The memory for the PGM-FI warning light on the dashboard
will be erased when the ignition switch is turned OFF;
however, the memory for the LED display will not be
canceled. Thus, the warning light will not come on when the
ignition switch is again turned ON unless the trouble is
once more detected.
... blah blah...

Civic at www.autozone.com , too, under "emission controls."
