You counted the separator code, that last code is 34.
It goes: quick flash - KOEO codes - repeat once - separator code - CM codes - repeat once
If I remember correctly, the quick flash is all the codes flashed at like 100x speed.

Laughing gas - Okay, I'm going to re watch it when I get home. I understand the koeo codes and then they repeat once. After that I'm generally confused what I'm doing wrong haha..

Ohhh... so I just need to transfer everything 1 digit over to get the correct codes. 22, 41, 31, 32, 34 then it repeats twice.. okay now that makes sense! Thank you!
How've i have code 10 as an issue then too right?

Yes, it is separating the KOEO and CM codes.

Laughing gas - sense you've been assisting me so far. I looked to see how exactly you do a cm read. I found this post from someone else. Guessing i did it wrong?. I jumped the self test out to the self test in. If you have a minute can you tell me the proper way to jump to test both koeo & cm codes and how its done. I read elsewhere that one set the motor has to be cold & the next hot. I just did koeo on a cold motor with the jump i stated above to get the codes in the video. Thanks in advance!

CM codes are ones that the PCM picks up as they show up, as you can't check codes while driving.
When you turn the key, it runs KOEO - (separator code) - CM
It's best to run it in a warm motor, but it works either way.

This is why myself and a most others use a code reader like the Innova 3145. It displays the actual codes so you don’t have to try to count the flashes.

Self test-in jumpers to Sig-Rtn or ground to trigger the computer to enter the test. Self test-out is used to view the codes - it is tied to the check engine light. I think you have the digits sorted now.
