You should only hear the brake release when steping on the brake pedal and attempting to move. If it displays gate when trying to move, id recommend checking the gate switches as even if the gates are down if a switch is bad, it can make the lift think the gates are up.

Event code 208 is a due to a steering self test failure. When starting up the lift, it should move the steer wheel, which will make a noise and move the lift slightly. The code pops up either because the steering motor is wired wrong, there is a bad ecr2 (steering encoder), or a bad steering module. This code disables all travel functions but still allows lift and lower functions. With these older lifts sometimes when codes disable functions they will throw other messages on the screen that mean nothing. I recommend looking into the steering motor to solve event code 208.
