This file applies to Cummins ISB6.7 CM2250 fault diagnostics for SPN 4765 FMI 2, with the associated procedure table also referencing ISC8.3 and ISL9 CM2250, ISX15 CM2250, GX CM2250, ISX11.9 CM2250, QSL9 CM2250, and QSB6.7 CM2250 engines. The fault concerns the aftertreatment diesel oxidation catalyst intake temperature sensor, located in the aftertreatment system between the turbocharger outlet and the intake of the exhaust aftertreatment, with OEM service manual location details required. See the manufacturer website at Cummins official site.
Who needs this Cummins 3315 troubleshooting manual
Workshop owners, diesel mechanics, and diagnostic technicians need this manual when Fault Code 3315 is active, regeneration is disabled, diesel exhaust fluid injection is disabled, or the ECM uses a default aftertreatment diesel oxidation catalyst intake temperature value. The procedure supports checks with INSITE™ electronic service tool, sensor and connector inspection, resistance checks for open circuits and shorts, aftertreatment DPF temperature sensor interface module diagnosis, OEM harness testing, DOC soot and crack inspection, ECM calibration review, and fault clearing.
