Lead driver - I was able to successfully upload it to my YouTube. Please take a few minutes of your time to take a glance at it and give me your thoughts.

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..

​​​​​​Long pause, 1 flash (code 10) long pause

Your first CM code is 22, not 12, that "1" is the separator code.

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?

So I just re watched the video and that makes much better sense. I guess my question is that single flash (code 10) it always pops up as a single flash with a pause before and after it 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!

KOEO codes are hard faults that the computer can "see" (a voltage out of range, a solenoid not responding, etc)

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.

4wd High- As was mentioned, code 10 is not an actual code but is a separator between active codes and codes that are stored in the memory.

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.
