....but you are. You are getting an indicator Icon. Why not just turn on the Parking Brake Icon when you put in Park and be done with the programing. Why go to the trouble of programing a Hold for Parking Brake feature in the code that is redundant and doesn't really do anything? And why would it activate the actuator again if it is already done?....You're not getting anything additional by holding the button in, but there's of course no harm in doing so either!
