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...

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. Each fuel injector has a specific barcode. The barcode data contains specific injector information. This barcode information needs to be entered into the ECM with INSITE™ electronic service tool. If an engine is found to have incorrect injector barcode values, the correct injector barcode values must be entered. The engine symptom of incorrect barcode values can include rough idle. The factory installed injector barcode values can be...

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 this fault code is active and there has been damage to the aftertreatment system, the permit switch may have prevented the aftertreatment system from performing a mobile (active) regeneration. Consult with the OEM if the aftertreatment system has failed due to the permit switch. Possible repairs: 1)If necessary, recalibrate the ECM.

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. If this fault code can be triggered when fuel dilution of the lubricating oil is possible. Change the engine lubricating oil and clear the fault code using INSITE™ electronic service tool to reset the Maintenance Monitor feature. Possible repairs: 1)Change the engine lubricating oil.

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. Fault Code 281 will most likely come active while operating at a steady state loaded condition. At this condition, commanded fuel pressures are highest and the pump’s pressure balance is affected the most. If a high pressure seal has failed, pump head drain flow will be excessive. If seal damage has progressed far enough, the engine may not start because of an inability to develop fuel rail...
