      DOT Inspection Note:

To demonstrate that the actuator and trailer brake system are functioning properly, adjust the up arrow on the in-cab controller until the system is set at its maximum gain setting (i.e. 6 green LED’s illuminated). Press and hold the red STOP button on the in-cab controller and attempt to drive through the trailer brakes. This will apply the maximum power to the trailer brake magnets and will demonstrate to DOT personnel that the trailer brakes are functioning properly.
