DieselCodes: a fault-code lookup with a drive-safety verdict
A truck fault-code decoder for J1939 SPN/FMI and factory codes, with lookup options across makes, systems, and symptoms.
- For
- Truck drivers and diesel technicians
- Worth noticing
- The input accepts a fault list separated by commas, spaces, or line breaks, not just a single code.
Field notes
The lookup accepts a single fault code or a pasted list separated by commas, spaces, or line breaks, and the page offers automatic make detection plus J1939 SPN/FMI and dealer/OBD modes. Its catalog is organized across vehicle makes, systems, and symptoms; the homepage says the fault names and factory tables are in Russian, while the interface and standard FMI meanings are translated. The drive-safety verdict is presented as a feature, but its reliability cannot be established from the extracted page.
