Most new Chrysler platforms have started using a different style Data Buss communication system. With this new communication system, the control for most sub-systems will be different than what we have seen over the past years. These changes will be introduced as the new platforms are introduced. The Compact Wide Platform was the first of this completely new Buss system and was introduce in the in the 2013 Dart, Jeep Cherokee and then the Pacifica. Be aware the Ram trucks had a mid-year change in 2013, so there 2 different schematics and diagnostics.
