Default Blinking check engine light

My dad called me saying his bonne'* check engine light came on and was blinking at him. I've never seen mine do that before, does that mean anything in particular...

The official FSM terminology is "possible catalyst damaging condition"

Most likely he has a misfire from a bad coil, plug or plug wire.
