Applicable truck models
The document applies to Cummins CM2250 engines where Fault Code 3245 is used for an aftertreatment diesel particulate filter mechanical system not responding or out of adjustment condition. The file identifies ISB6.7 CM2250 and lists associated procedure coverage for ISC8.3 and ISL9 CM2250, ISX15 CM2250, GX CM2250, ISX11.9 CM2250, QSL9 CM2250, and QSB6.7 CM2250. The DPF is installed in the exhaust system by the OEM, so vehicle-specific component access may require the OEM service manual. See the official manufacturer website at Cummins official website.
