The Cummins M Series Engine is a very popular heavy-duty truck, but like all engines, its ECM, in the case of the Cummins M11 ECM, can experience problems from time to time.

Common Cummins M11 ECM Problems

Wiring Issues

The ECM relies on a complex network of wiring to receive input from various sensors and control the engine. Damaged, frayed and improperly connected wiring often causes ECM failure.

Battery Problems

A weak battery can cause the ECM to malfunction, so it is important to replace the battery if it is not providing sufficient power to the system.

Sensor Issues
