The Freightliner ServiceLink software communicates directly with the Freightliner proprietary control modules on vehicles. When you specify a vehicle, we use the software to program its SmartPlex Electrical System. If you want to add additional functionality to SmartPlex, ServiceLink allows you to download new programming to the truck at your facility. You now have the flexibility to add whatever combination of features a customer needs at any time. And Freightliner does all the programming for you. We have a full suite of features from our SmartPlex Parameter Database for you to choose from as well as the ability to create custom parameters for your unique needs. If you ever need to modify or expand the system for a vehicle, Freightliner will make new parameters conveniently available for you to download from our network.
