The "pedal dance" will not only reset the CEL, it will allow you to read the codes. Simply pause after step 4 in the procedure in the link above (when the CEL starts blinking). The blinking pattern shows the codes that are set. To clear them, continue with step 6 and subsequent.
Nice one, didn't know there is a hidden morse code generator there. Do you have a list of what those blinks are referring to? For example, P1051, what would be the blink sequence?
