Common Cummins ECM failures we repair
We fix these on the bench every day. Wiring and connectors can mimic ECM failure, so we test first.
- Injector driver faults. The circuits that fire the injectors burn out or go weak, so the engine misfires, runs rough, or loses a cylinder. We rebuild these driver stages on the bench.
- No communication. The module stops talking to your scan tool over J1939, usually from a failed internal power supply. We track the dead spot and bring it back.
- Heat, vibration, and intrusion damage. Cracked solder joints, blown fuses, and oil or moisture in the board cause faults that come and go. We repair them at the component level and bench-test before it ships.
