First things first, check to make sure the brake lights come on when you tap the brake pedal. Try numerous times.
Cruise control systems rely on a functioning brake pedal switch. If the signal is "implausible", then the cruise control system has no way to tell it when to deactivate.
If you have a way to interrogate the vehicle's various computers for DTCs, that would be the best way to go forward.
