Brake Pressure Applied Switch
Brake Pressure Applied Switch
NOTE: The Brake Pressure Applied Switch is present on vehicles equipped with speed control.
All vehicles have a single Brake Pressure Applied (BPA) switch. A BPA switch provides a backup for the Brake Pedal Position (BPP) switch.
Normally, a brakes-applied signal from the BPP switch will disengage the speed control. If the BPP switch signal is lost, the BPA switch will then
supply the brakes-applied signal to the speed control system.
