The Engine Control Module (ECM)  plays a vital role in the proper functioning of modern diesel engines. It monitors and controls various engine parameters, such as fuel injection timing, air-fuel mixture, and ignition timing. However, like any electronic component, ECMs can fail, leading to engine performance issues and potential breakdowns. Cummins is one of the most popular diesel engine and ECM manufacturers in the world , but even their ECMs tend to malfunction after a certain time. In this article, let’s look at common reasons why Cummins ECMs fail.   1.   Electrical Overload or Surge One of the primary causes of ECM failure is electrical overload or surges. A sudden increase in voltage, such as from a faulty alternator or a power surge in the electrical system, can damage the ECM's delicate circuitry. Over time, repeated exposure to electrical overload can lead to component failure and ECM malfunction. 2.   Heat and Environmental Factors ECMs are usually located in the engine
