Yup, I'm a liar. Perhaps you should tell us why this happens and what causes it?
You are a true asset to this community, whew.
bada44, on some trucks. if you adjust beyond what the ABS module is designed for, the cruise will not work or will work in a smaller range of speeds. The tire size adjustment is and can only be done one way. The way we do it, the same way our competitors do it. The fact that the speedo is correct indicates that it was changed properly.
Programming ABS controllers to accept a different range of inputs from the speed sensors is not something anyone wants to do, nor likely will ever offer. GM trucks have dealt with this issue for years on pre 07 models, and nobody ever bothered to try programming the ABS module to get around it as its a tricky subject with much liability concern. Hopefully this explains why this happens. The plan is not to leave you with no cruise control, but unfortunately if the speedo is corrected for tires taller than the ABS is capable of dealing with, the loss of cruise is possible.
Finally we agree on something....
Your explanation sounds reasonable with one problem. No one is engaging their cruise outside the parameters that are new too them using the truck. Cruise simply stops after installing a tune. My main issue with you is that you and diablo always fall back to the problem is the individual truck and not a diablo problem. That line of bs has really gotten old over the years...
