Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 3389 PID: SPN: 3058 FMI: 10/10 Engine Exhaust Gas Recirculation (EGR) System – Abnormal Rate of Change
Posted by PerDiezel Solutions on
Lamp:Amber Reason:The measured EGR flow is not meeting the commanded EGR flow. Effect:Possible reduced engine performance. Circuit Description:The Exhaust Gas Recirculation (EGR) differential pressure sensor has two ports that sense exhaust pressure. The sensor outputs a voltage which represents the pressure difference between the two ports located across an orifice in the EGR tube. The Engine Control Module (ECM) uses this pressure to determine how much exhaust gas is flowing in the EGR connection tube to the intake manifold. This information is used to control the EGR valve for correct emission levels. The ECM provides a 5 volt supply to...
Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 3565 PID: SPN: 5394 FMI: 3/3 Aftertreatment 1 Diesel Exhaust Fluid Dosing Valve 1 Circuit – Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Lamp:Amber Reason:A circuit error has been detected in the aftertreatment diesel exhaust fluid dosing valve circuit. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment diesel exhaust fluid dosing valve is controlled by the ECM. When the Engine Control Module (ECM) commands DEF dosing, the ECM sends a Pulse-Width Modulated (PWM) signal to the dosing valve, which opens the dosing valve and allows DEF to be sprayed into the exhaust stream. Component Location:The aftertreatment diesel exhaust fluid dosing valve is installed in the exhaust system. It is mounted directly to the aftertreatment decomposition tube, before the Selective Catalytic Reduction (SCR) catalyst. Installation...
Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 3718 PID: SPN: 3216 FMI: 13/13 Aftertreatment 1 Intake NOx – Out of Calibration
Posted by PerDiezel Solutions on
Lamp:Amber Reason:A nominal system voltage mismatch has been detected by the aftertreatment intake NOx sensor. Effect:None on performance. Circuit Description:The aftertreatment intake NOx (Nitrogen Oxides) sensor is a smart device and communicates with the Engine Control Module (ECM) via the J1939 data link. The aftertreatment intake NOx sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J1939 data link. The NOx sensor is permanently attached to the NOx control module. They are serviced as a single component and can not be replaced individually. The aftertreatment intake NOx sensor is used to measure the NOx emissions...
Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 3838 PID: SPN: 2978 FMI: 9/9 Estimated Engine Parasitic Losses – Percent Torque – Abnormal Update Rate
Posted by PerDiezel Solutions on
Lamp:Amber Reason:A loss of communication has been detected. Effect:None on performance. Circuit Description:Normally, switches, accelerators, and other components are connected to the Engine Control Module (ECM) directly through individual wires. Multiplexing allows those same components to be hard wired to an Original Equipment Manufacturer (OEM) Vehicle Electronic Control Unit (VECU) or transmission Electronic Control Unit (ECU) in the cab. Then component values and states from components such as sensors, accelerators, and switches can be transmitted from the OEM VECU to the OEM ECM over the SAE J1939 data link. Messages sent from OEM VECUs or transmission ECUs are received by...
Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 3866 PID: SPN: 3364 FMI: 1/1 Aftertreatment Diesel Exhaust Fluid Quality – Data Valid But Below Normal Operating Range – Most Severe Level
Posted by PerDiezel Solutions on
Lamp:Amber Reason:The Diesel Exhaust Fluid (DEF) quality has been detected to be below a critical threshold. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment diesel exhaust fluid quality sensor is a smart device that communicates to the ECM via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor performs its own internal diagnostics and reports malfunctions back to the primary Engine Control Module via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor is used to measure the concentration of the aftertreatment diesel exhaust fluid in the tank. Component Location:The aftertreatment diesel exhaust fluid quality sensor is located in...
