Truck Fault Codes

Diagnostic fault codes, or DTCs, are the codes your commercial truck or diagnostic tool displays when your vehicle has an issue. Diesel Repair contains a library of all known diagnostic fault codes for commercial trucks from when electronic control modules (ECMs) were first introduced all the way up to current year and models. Our system contains both the OEM and the generic fault codes, so no matter how you retrieve those codes from your vehicle you are easily able to find repair information.

 

Endless Data just for you

For free users of Diesel Repair, you will be able to search and view the entire database. We’ll give you descriptions of each truck fault code, along with “quick repair” information that will summarize possible failed components that could cause the fault code to appear.

For paid users, you will also receive the added benefit of view the detailed step-by-step repair information for each fault code. These guides have been developed by the subject matter experts at Diesel Laptops, and you’ll find that the information, look, and feel is consistent across all manufacturers.
