Useful Information

Description and Purpose:

This New Genuine Cummins (ECM) Engine Control Module with Part number: 5677631, manages critical engine functions in Ram 2500 and Ram 3500 trucks (2019–2022) with the 6.7L L6 diesel. Acting as the engine’s central processor, it coordinates fuel injection, turbocharger response, and exhaust management while interpreting sensor data to maintain optimal performance. 

Why Replacement is Important:

A faulty ECM can trigger engine warning lights, reduce power output, or cause erratic performance. Installing the correct Cummins module restores accurate engine management, preventing drivability issues and potential damage to other engine components.

Impact on Vehicle Performance:

With the ECM properly installed, the 6.7L Ram trucks maintain consistent power delivery, smooth acceleration, and efficient fuel usage. It supports reliable operation under heavy loads and ensures the engine performs safely and efficiently across all driving conditions.

Manufacturer Information:

Cummins® delivers durable engines and powertrain solutions trusted worldwide in commercial, industrial, and off-highway applications.
