Ultimate Guide to the Mitsubishi 4M51 ECU Pinout The Mitsubishi 4M51 is a 5.2-liter, 4-cylinder overhead camshaft (OHC) diesel engine. It is widely used in commercial medium-duty trucks, most notably the Mitsubishi Fuso Canter. Because these vehicles operate under heavy loads and harsh conditions, electrical diagnostics often require a deep understanding of the Engine Control Unit (UMEC/ECU) pinout configuration.
