Diesel Laptops is excited to bring you the Truck Fault Code Android app which gives you access to over 40,000 diagnostic trouble codes found on commercial trucks. This app allows you to search by manufacturer, model, and code number. Each diagnostic fault code will give you as much information as possible on the components related to that diagnostic code, along with a list of probable causes so that you can isolate and repair your vehicle. This is the only app you will find that is dedicated towards the commercial trucks industry, and is the most complete library you will find.

For commercial truck diesel engines, every single major manufacturer is covered. This includes CAT, Cummins, Detroit, Mack, Volvo, International, HINO, Isuzu, MBE, PACCAR, Ford, Sprinter, GM, and many more.

All electronic transmissions that are used in the commercial truck industry are also included. The list includes Allison, Detroit, Eaton, Volvo IShift, and Mack mDrive.

We've also included repair information for all known cab controllers (Such as Freightliner, International, Kenworth, Peterbilt, Mack, and Volvo), ABS systems (Wabco, Bendix), and other sub systems as well.
