Abstract: An apparatus, system and method for checking brake operation suitable to be executed by a single person is disclosed. A trigger is received from a trigger device. In response to the trigger, it is determined whether the vehicle is in motion. If the vehicle is determined to be substantially not in motion entering the test mode. In the test mode, sending a waveform to a brake actuator and causing the brake actuator to generate a sound audible to the person performing the test if a brake circuit is operational.
