The manual covers medium-duty MaxxForce DT, 9 and 10 and heavy-duty MaxxForce 11, 13 and 15 engines. Symptom trees address frequent parked regens, no-start / starts-and-stalls, SPN 3719 and SPN 3936 faults, and black smoke, cross-referenced to DOC, DPF and sensor fault codes such as DPFIT, DPFOT and DPFDP. Parked-regen checks list expected DOCOT and DPFOT temperature ranges. Product and dealer support is available from the International Trucks website.
