GM 12654884-U Used LML Duramax Engine Control Module
This is a used Genuine GM Duramax Diesel replacement electronic control module (ECM). All units have been checked and tested before shipment to guarantee integrity. ECMs are blank and will require re-flashing. Unfortunately the LML platform does not support bench flashing. Your truck would need to be present to flash. This service is generally available at any GM dealer for $100-$150. Please verify fitment with your dealer or match to original ECM.
