Where to find the part number
The part number is printed on the label on the ECM itself. Caterpillar numbers look like 223-1235-00 or 10R4094 (the two digits after the second dash are a revision code), Cummins numbers have 7 digits (3408303) and Detroit Diesel numbers 8 digits (23519307). If the label is missing or unreadable, the engine serial number tells us which ECM you need.
Not sure which ECM you need?
Send us your engine model and serial number, or the part number on your ECM, and we'll tell you whether to repair or replace it, and what it costs.
