Vehicle Specific Wiring

 A growing number of vehicles built since 2003 contain communications
 systems within the wiring to enable certain modules to talk to one another.  
 This system is known as CAN (Contorller Area Network), which was first introduced
 in 1992 for many Mercedes-Benz vehicles and now can be found in many other
 manufacturers. The CAN bus system controls relevant information being transferred
 around the vehicle, allowing for displays to be activated either in the instrument or
 display panel. The trailer stability programme carried within the CAN network is
 being introduced into many new vehicles, including the new Volkswagon range.
 Once a vehicle specific wiring loom has been fitted, a simple programming change
 will be arranged with the dealer to enable the TSP to be activated.
