97 road king MM intake engine code not making sense
The other day I was out riding and my check engine like comes on for 8 Seconds after I start the bike. Per the book I believe it's a stored code cuz it does turn back off. I went to pull the code by turning the ignition on and off and leaving it on the 3rd time. My problem is the codes it's displays aren't codes at all. I made a video take a look.
Also bike does seem to run just fine. I wouldn't know anything was wrong of it wasnt for the engine light.
Also I had to cut the begging of the video down to get it to fit the 20mb limit. So you don't see all 6 slow flashes on the begging.
All help is appreciated thank you

I do not download unknown stuff so i can not see.
But the MM system will give a rapid flash just before the code and then rapid flash after the code.
The actual code is a slow flash per number for first number and then a two second pause..
Then second number of code...then rapid flash
A code 56 crank/cam sensor.. will trigger with just about any bad start.
So a code 56 would be rapid flash...then slow flash, slow flash, slow flash, slow flash, slow flash...pause for about two seconds...then slow flash, slow flash, slow flash, slow flash, slow flash, slow flash...then a pause and back to rapid flash.
Removal of negative battery cable clears codes.

Yep all rapid flashes just repeating counts with slight pause, mean no codes.
Also, if you have a code in the first place, when you start the bike up, instead of the oil light going out quickly in about a second, it will stay on for about 20 seconds before it goes out to let you know that there is stored codes.
