Brake Release Switch

The powertrain 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 powertrain control module. The powertrain control module will then shut off all cruise control outputs to the electronic throttle system.
