We are excited to announce that we have added detailed troubleshooting trees for more Cummins engines. This includes the Cummins ISC CM554 (1998-2002), Cummins ISL CM554 (1998-2003), and Cummins ISM CM875 (2003-2006). These detailed, step-by-step directions will help any technician easily find the problem to their code and make a quick repair. These are all included with our premium membership package, which is $200 per year. We now have repair information on every diagnostic code from a class 6 to class 8 truck, along with over 6,700 step-by-step PDFs as well.
