Which one of the following describes a vehicle's foot brake wire as tested for connection to a remote start?

A vehicle's foot brake wire is designed to send a voltage signal when the brake pedal is engaged. When tested for connection to a remote start system, the correct description would be that the foot brake wire outputs +12 volts with the brake pedal pressed. This positive voltage signal indicates that the brake system is activated, which is a safety feature preventing the remote start system from engaging while the vehicle is in gear or moving.

This mechanism ensures that the vehicle cannot accidentally start when the driver is not ready or aware, providing an essential safety function in remote start systems. The other options do not correctly reflect the behavior of a foot brake wire when engaged. The expectation is to see a positive voltage, confirming that the system recognizes the brake has been applied.
