can tow/haul be accidentally disabled?

[Superado]

went on a mountain cruise recently and wanted to use tow/haul to keep the tranny temps down...
button didn't work at all...light didn't even come on...
I was wondering if we could have accidentally disabled it while working on the idle tune...

anyone?
