Applicable truck models
The extract identifies this fault procedure across Cummins CM2250 engine families including ISX11.9 CM2250, ISX15 CM2250, GX CM2250, QSL9 CM2250, and QSB6.7 CM2250. The document states that the aftertreatment diesel particulate filter mounting location is dependent on the OEM, so component location must be checked in the applicable OEM service manual. This file is relevant where Fault Code 3375, PID S115, SPN 5397, FMI 31 is active and the ECM has detected that active regeneration is being requested too soon after a successful regeneration. See the manufacturer’s official resources at Cummins official website.
