Applicable truck models
This document covers Cummins engines equipped with the CM2250 electronic control module across multiple displacement families: the ISB6.7 (Bulletin 4022254), ISC8.3 and ISL9 (Bulletin 4022257), ISX15 (Bulletin 4022250), and ISX11.9 (Bulletin 2883445). These engines are found in medium- and heavy-duty trucks manufactured between 2010 and 2012. Fault Code 3714 is an information-only code triggered when other critical engine performance fault codes remain active; it causes an immediate engine power derate and illuminates the amber CHECK ENGINE lamp. The ECM monitors this condition continuously during engine operation. For official Cummins technical resources, visit the Cummins corporate website.
