Reason:Aftertreatment Diesel Particulate Filter Differential Pressure – Data Valid But Above Normal Operating Range – Moderately Severe Level. The soot load of the aftertreatment diesel particulate filter has exceeded the recommended limits. Effect:Possible reduced engine performance Circuit Description:The engine aftertreatment system monitors the soot load in the aftertreatment diesel particulate filter. Under normal operating conditions, the aftertreatment diesel particulate filter is self-cleaning, where soot is converted to carbon dioxide, nitrogen, and water. Under light load operating conditions, it can be necessary to perform a stationary regeneration of the aftertreatment diesel particulate filter. The soot load in the aftertreatment diesel particulate...

Reason:Aftertreatment Fuel Shutoff Valve 1 Circuit – Voltage Above Normal, or Shorted to High Source. High signal voltage detected at the aftertreatment fuel shutoff valve circuit. Effect:Possible reduced engine performance Circuit Description:The aftertreatment fuel shutoff valve is used to disable the fuel supply to the aftertreatment system. Component Location:The aftertreatment fuel injector is installed in the exhaust system in the turbocharger adapter pipe. The aftertreatment fuel pressure sensor and aftertreatment fuel shutoff valve are installed in the shutoff valve manifold. Conditions for Running the Diagnostics:This diagnostic runs when the aftertreatment fuel shutoff valve is commanded on. Conditions for Setting the...
