This diagnostic function starts monitoring the DEF dosing pressure when the DEF pump is set to ?Running? mode. The aftertreatment control module (ACM) keeps track of the time when the pump is not in the ?Running? mode. When the time that the pump is not in “Running” mode accumulates to more than 25 % of a predetermined amount of time a DTC will set. Conditions for diagnostic trouble code (DTC):1) Dosing failure Observable symptoms1) Leakage, pressure side Probable cause1) Low fluid level in the tank2) Leakage from hoses or connections3) Aftertreatment Diesel Exhaust Fluid (DEF) Return Valve4) Aftertreatment line connections...

This Diagnostic Trouble Code (DTC) monitors and evaluates malfunctions in the (EGR) Exhaust Gas Recirculation Diff Pressure. A faulty (EGR) Exhaust Gas Recirculation differential Pressure can lead to uneven running and response problems. Conditions for diagnostic trouble code (DTC):1) Abnormal system response, most likely high flow Observable symptoms1) Possible engine de-rate2) Exhaust leakage Probable cause1) Connector2) Wiring harness3) Clogged ports4) EGR Cooler5) EGR system pipe and connections6) EGR differential pressure sensor Detailed information Activation1) The diagnostic trouble code (DTC) is first set after 30?min when driving with varying engine loads2) At idle the diagnostic trouble code (DTC) is normally not...
