The vehicle has certain readiness codes that are part of the on-board diagnostics for the emissions systems. If the vehicle's battery has been disconnected or gone dead, if the DTCs have been cleared, or if the ECM has been reset, these codes are reset to incomplete. In some states, part of the emissions testing is to make sure these codes are set to complete. If all of them are not set to complete, the vehicle may fail the emission test, or the test cannot be finished.
To check if the readiness codes are complete, turn the ignition switch to ON (II), but do not start the engine. The MIL will come on for 15-20 seconds. If it then goes off, the readiness codes are complete. If it blinks several times, one or more readiness codes are not complete. To set readiness codes from incomplete to complete, do the procedure for the appropriate code

Glad you were able to find the solution.
Sorry my post irritated you when I'm trying to help you. Do you realize how many folks post in this forum and say that an issue is "absolutely" not "x, y or z" and when you finally help them get to the solution you find that they were dead wrong and it was 'x, y or z" after all?

But it's good to have it resolved. I've read a few other posts on s2ki where people were never able to get to the bottom of this phenomenon.

The Honda resetting procedure is in the manual, I think.
