Who needs this Cummins fault 3313 manual
Workshop technicians need this Cummins fault 3313 manual when active aftertreatment regeneration is disabled, DEF injection is disabled, EGR operation is affected, or engine torque reduction may follow extended operation with the fault active. It is useful for checking INSITE™ fault status, inspecting dirty or damaged pins, measuring resistance, checking for pin-to-pin or pin-to-ground shorts, evaluating the aftertreatment DPF temperature sensor interface module, and confirming ECM calibration.
