2014 GMC Sierra 1500 SLE Cruise Control Not Working

[2014gmcsierra1500]

Hey guys. I researched as much as I could before posting this. I recently purchased a 2014 GMC Sierra 1500 SLE (119k miles) and my cruise control doesn't work. I have a 10 hour round trip drive coming up and would really like to have my cruise control for then. I replaced my brake pedal switch which I read to be the common culprit, but that didn't work. There are no codes on the dash, no stored DTCs. Truck runs great/no issues except my cruise control just doesn't work. I can click the white button to activiate it, and then when I try to set it at a certain speed nothing happens. Any fuses to check, where should I go from here? Would really appreciate any help, don't want to have to take it to a shop and pay for a fix if it's relatively easy.

Do you have a scanner that can read all of the modules in the vehicle, not just engine and transmission codes?  Any lights on the dash at all like ABS, traction, brake warning, etc.?  

 

It could simply be the switch on the wheel is bad, but there is a big list of inhibits that can cause cruise not to work.  75 of them to be specific.

Thanks for the reply. No I just have a cheap scanner for basic codes. For a while I did have a stabilitrak and brake assist light pop up, but it was very intermittent. Sometimes it would go away on startup and then come back after 3-4 startups. I haven't had it pop up in about 2 weeks though.

I'd scan it with a reader that can see more.  If you are interested in buying one that can read more, Bluedriver is a great option, or Topdon.

Ok I might have to do that, instead of shooting in the dark repairing random things that may or may not work.

Hey yall. Got an update. Took truck to a local mechanic who had a very sophisticated code reader. He cleared some brake pedal position codes and did a "relearn/calibration" on it and now my cruise control works without issue. Took about 10 minutes and gave him $20 for his time. I don't know why I never knew you had to calibrate the switch if you installed a new one, but I'm glad I got it figured out. Thanks for y'alls input.

Thanks for the tip on these readers. I was just able to pick up a BlueDriver reader on Amazon on sale for $79.95. Definitely has more capabilities than my older BAFX reader.
