Cummins Guidanz

Reviews are 2yrs old

Mobile mechanic for a Cummins powered bus fleet. The app gives you translation of J1939 codes with brief explanations. It will not clear codes, so it is back to the shop for more complicated jobs. I’m finding it good for sensor swap outs or disconnects. Avoid calibration updates as Bluetooth is not as reliable as a cable connection(a shop job for sure). I hope to see more development of the app. For those whom can afford the telematics subscription, good luck. For the poor man, go with QuickServe online or hard copy manuals.

So the idiots at Cummins decided to ditch quickserve app and use this guidance trash that doesn’t even work. This has become a money making for them. Also, while you are it Cummins needs to put better product on the road besides these machines that keep breaking down. It’s time for CAT to come out of retirement and show these vampires at Cummins how to make a real engine that last more than a million miles.
