Brake Switch (Cruise Control): Description and Operation
Brake Release Switch
The cruise control module uses an electronic brake switch which contains one normally open and one normally closed switch contact. These switch
contacts are part of the zero adjust brake switch.
When the brake pedal is depressed, the two brake switch contacts change their input state at the cruise control module. The cruise control module will
then shut off all cruise control outputs.
