Had to disconnect the PCM to check a few things, after that, all is reconnected. Key on engine off I was checking a few things on scanner, and noticed that the CEL slowly flashes a few times. It goes out upon engine start. It did this for a few drive cycles. This got my curiosity up, and eventually found that if there are monitors that are not yet run, the CEL would do this. After all monitors are run, CEL remained solid with KOEO. Thought to share this, nice feature before trip to annanul inspection without involving scanner. Cheers.
