Troubleshooting ECU Programmed by Bodybuilders

Abstract

Having an Electronic Control Unit (ECU) which is programmable by external parties puts new requirements on troubleshooting. In this paper we describe how one could solve the problems of both troubleshooting additional equipment added by bodybuilders and facilitating their need to use signals from vehicles in an easy way in order to interact with their additional equipment. In this paper we look at bodybuilder's additional equipment for heavy trucks, but our technique for troubleshooting should be equally relevant for other applications with similar conditions.
