ECM Dataplate
The electronic control module (ECM) dataplate shows
information about the ECM and how the ECM was
programmed. The dataplate is located on the ECM.
The following information is available on the ECM
dataplate:
• ECM part number (PN)
• ECM serial number (SN)
• ECM date code (DC)
• Engine serial number (ESN)
• ECM code: Identifies the software in the ECM.
NOTE: Have the ECM code for the engine available when
communicating with a Cummins® Authorized Repair
Location.
NOTE: The presence of an ECM dataplate depends on
the manufacturing plant and the date the engine was
manufactured. If an ECM dataplate was not installed by
the manufacturing plant, calibraton data can be found on
the engine dataplate.
