pulled engine codes, need help on what they mean
Hey guys and gals, I pulled the codes today on my truck to see if there are any issues I need to address. It runs fine and no CEL on I just want to see if there is anything wrong w/ the truck. The first video is the KOEO test and the 2nd is the running test for stored codes. I'm hoping someone can tell me what these mean as I found it hard to tell what all the flashes meant. I did forget to do the brake test and the WOT test so I know those are in there. Any advice is MUCH appreciated. Links are below. Again the first is the KOEO test and the second is the running test. Truck was warm so I did know to do that.....Thoughts?

From what I can gather the stored codes are 538 536 632 538 536 632 in that order. I know it repeats but whats that mean.
I still can't figure out the key on engine off test. 112 is all I can get out of it

Engine off is 111 and memory is 111 (there is a single separator pulse in the middle) meaning no current issues and no stored codes. The first flash during the engine running test tells you to stab the throttle, step on the brake, and push the overdrive cancel button on the shifter. The three codes output during the engine running test just tell you that you forgot to do those three things.

You mean there is not anything in the stored codes? If so that is great but I can't believe there isn't something stored. BTW to anybody that watched the video, sorry about the door dinging. I forgot to shut it and didn't want to move the camera and miss a flash. Just turn the volume down

I'll go back through my notes when I last pulled codes and post what it gave me during KOER. After a second attempt (turning the wheels) it was not there.

I stand corrected. Evidently I missed the overdrive part when I ran my codes.

Engine codes, not sure what they mean
Pulled codes on my 93 f150 XLT 5.0 4eod 4x4
Pulled 3 times, same codes (used Innova code reader 3145)
turned OD switch to off after start and turned wheel with brake on 1/4 turn
KOEO
111 (Pass)
KOER
536 (Brake On/Off BOO circuit not activated) ??? what?
632 (OD cancel switch/no action during test) ??? is this a problem?
upon reading above further, during code 10 engine goose, do you switch off the OD then and turn the wheel?
Thank you
