Abstract
An apparatus for controlling a trailer parking brake status indicator in a tractor is provided that allow an operator to deactivate the indicator when the tractor is operating without a trailer using a pre-existing operator interface. The apparatus includes means for determining whether a trailer is coupled to the tractor and a controller configured to execute, when a determination whether the trailer is coupled to the tractor cannot be made, a process for controlling activation and deactivation of the indicator. The process includes determining whether a speed of the tractor meets a predetermined condition relative to a predetermined speed. The process further includes monitoring, after determining that the speed of the tractor meets the predetermined condition relative to the predetermined speed, for an activation command to activate a parking brake on the trailer. The process further includes deactivating the trailer parking brake status indicator responsive to the activation command.
