Recently, I reviewed the latest fault code information for the Detroit Diesel Electronic Control system (DDEC) and was astounded by the proliferation of fault codes in today’s modern diesel engines – so much so that I decided to do a little research to satisfy my curiosity.
I found some interesting facts about the DDEC system – the first electronic control system for an on-highway diesel engine. When it was released back in 1986, this system had only 43 fault codes and controlled only the engine timing and fuel injection.
Fast forward to today … the Detroit Diesel engine now has 943 fault codes and the system controls much more than timing and injection. With so many fault codes, it’s no wonder you may be a fault code overload sufferer. This is where Mitchell 1’s TruckSeries software suite can provide some relief.
