We repair Caterpillar ADEM ECMs every day — 3406E, C7, C9, C10, C12, C13, C15, C16, and 3126. If your ECM is doing one of the things below, there's a good chance we fixed the same thing this week. Most of it is repairable.
These show up across every Cat ECM, week in and week out. If your symptom is on this list, that's good news — it means we've seen it before and it's fixable.
What you see: a dead hole or misfire, a cylinder that drops out, or a power/derate complaint that follows the ECM, not the injector.
What's happening: the driver circuit inside the ECM that fires the injector has failed, so the module stops driving one or more injectors.
What we do: we repair the driver circuitry and bench-test every injector channel before it ships back, so you're not chasing the same dead hole again.
What you see: the ECM won't run right, asks to be reprogrammed, or comes back with its settings blank after a fault.
What's happening: the module dropped the customer parameters that were programmed to your engine.
What we do: we recover and reload your parameters so the ECM goes back in programmed to your engine and ready to run.
What you see: the engine starts and runs fine, but Cat ET (or your diagnostic tool) won't connect to the ECM. You can't read it, can't program it.
What's happening: the communication side of the module has failed while the engine-control side still works.
What we do: we get communication back on the bench so the ECM can be read and programmed again.
Don't see your exact symptom? Send it in anyway. These are the common ones, but Cat ECMs fail in other ways too, and we test every unit before we tell you what's going on.
Self-ship free, or add a prepaid UPS label. Drop-offs in Princeton, MN by appointment.
