Overview — ECM 4954431D
4954431D is the engine control module used on CUMMINS engines for the CM558 control family, managing the fuel, air and emission functions of the engine from the sensor inputs and calibrations. We can supply this ECM as well as related CUMMINS electronic control parts, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The ECM is built to the original CM558 hardware specification, with the connector layout, mounting and voltage range matched to the engine harness. The module reads the sensor inputs and drives the actuators according to the original calibration, and the housing seals the electronics against the engine bay environment. The module is supplied with the correct software family for the application. As an OEM-spec ECM, it restores the original engine control and diagnostic behavior.
Applicable Models & Applications
This ECM is used on CUMMINS engines in the CM558 control family, including the engine series that use this control module for their fuel and emission systems. The family reference CM558 identifies the control architecture for the module. Typical applications include generator sets, industrial engines and construction equipment. Confirm the ECM part number, harness connector and calibration against the module removed from your engine before ordering.
Maintenance & Replacement
Diagnose the ECM with the correct service tool before replacement, checking for communication faults, sensor circuit faults and power supply problems. A failed ECM shows as no-start, shutdowns, fault codes and erratic engine behavior. When replacing, disconnect the batteries, swap the module, and confirm the connector pins are clean and seated. Verify the calibration matches the engine and perform the required programming and diagnostic checks after installation.
Price Reference (USD)
The reference price for this ECM (4954431D) is approximately USD 300 – 1,200 per unit depending on grade, core condition, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.

Value & Service
Electronic control modules must match the harness and calibration exactly, so we verify 4954431D against the CUMMINS CM558 specification and confirm the connector and software family before dispatch. We stock the ECM and the related sensor and harness parts and can ship them with the diagnostic support documentation in one tracked order. Our team will help you confirm the correct module for your engine serial range.
