Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. This fault becomes active when the ECM detects an open in the fuel pump actuator circuit. Causes of this fault code are a short circuit to a positive voltage or an open circuit in the fuel pump actuator circuit. If there is high harness resistance or an intermittent open circuit, Fault Code 2311 can have high inactive counts. If the fault code is intermittent, look for causes...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. The aftertreatment system will try to meet target temperatures at the outlet of the diesel oxidation catalyst during a regeneration event. This fault code is activated when the control system detects that excessive fuel is entering the exhaust system, in an attempt to meet the target temperatures at the diesel oxidation catalyst outlet temperature sensor. Possible causes: 1)Soot plugging the front face of the aftertreatment diesel oxidation...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. The aftertreatment system will try to meet target temperatures at the inlet of the diesel oxidation catalyst prior to beginning a stationary regeneration event. This fault code is activated if the engine is not able to meet the commanded minimum exhaust temperature required at the inlet of the aftertreatment system. This is prior to any aftertreatment fuel injection into the exhaust system. Possible caused: 1)A leaking exhaust...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM. Possible causes: 1)Boost leaks in the charge air cooler plumbing2)A malfunction of the variable geometry turbocharger (VGT)3)A malfunction of the exhaust gas recirculation (EGR) valve4)A faulty in-range EGR differential pressure sensor5)A faulty in-range boost pressure sensor6)A faulty in-range barometric pressure sensor7)A cylinder misfire or overfueling. Possible repairs: 1)Repair or replace the leaking component.2)Clean or replace the charge air cooler3)Replace the intake manifold pressure sensor.4)Replace the barometric pressure...
