Common Cat ECM failures we repair
Cat ADEM ECMs tend to fail the same few ways. We fix all of these on the bench, every day:
- Injector driver failure. A dead hole or misfire when the ECM stops driving an injector. We repair the driver circuit and bench-test every channel.
- Lost customer parameters. The settings programmed to your engine drop out. We recover and reload them.
- Runs, but no communication. The engine runs but won't talk to Cat ET. We get communication back so it can be read and programmed.
