Intermittent Cruise Control Issue

If you can tell from my threads I have quite a few small electrical issues I’m trying to fix. The last one being my cruise control. Couple weeks ago it began only working part of the time. I’ll click it 50 times without a minute and it won’t turn on, and then 15 minutes later I’ll click it once and it is working fine. It’s like this all the time. The only function that doesn’t work is the on/off on the lever. All the other functions work when it is turned on. Anyone else have a similar issue? Did you end up having to replace the entire cruise control stem? I’d like to not have to do that if possible, since it is only the one button not functioning correctly. Thanks for the help!

 

@Drewb5 Do you still have other CEL codes as shown on other thread? Maybe ABS problem/code is affecting the CC?

 

These are the codes I have remaining from my repair spree.

 

C1201 looks like it could be ECM related. This could be many things. Fortunately, it may be a simple zero point calibration. https://www.tundras.com/posts/1641559/ (ABS VSC Codes) https://ricksfreeautorepairadvice.com/c1201-toyota/ (C1201). Also, the U0129 could certainly affect the cruise control since it is brake related.
