Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 5656 PID: SPN: 3227 FMI: 10/10 Aftertreatment Outlet Oxygen – Abnormal Rate of Change
Posted by PerDiezel Solutions on
Lamp:Amber Reason:The outlet NOx sensor oxygen reading is not valid. Effect:None on performance. Circuit Description:The aftertreatment outlet NOx (Nitrogen Oxides) sensor is a smart device and communicates with the Engine Control Module (ECM) via the J1939 data link. The aftertreatment outlet NOx sensor performs its own 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 outlet NOx sensor is used to measure the NOx emissions at the outlet...

Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 5864 PID: SPN: 5864 FMI: 3/3 Aftertreatment 1 Diesel Exhaust Fluid Pump Command Circuit – Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Lamp:Amber Reason:A short circuit to battery has been detected in the diesel exhaust fluid pump command circuit. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment diesel exhaust fluid dosing unit performs many functions, one of which is to generate adequate diesel exhaust fluid pressure in the lines, using a pump, to allow for dosing. The ECM provides a battery voltage supply and a ground to the diesel exhaust fluid dosing unit. The ECM also supplies a signal to the dosing unit to control the diesel exhaust fluid output. This signal changes, based on the diesel exhaust fluid pressure being commanded. Component...
Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 5865 PID: SPN: 4375 FMI: 4/4 Aftertreatment 1 Diesel Exhaust Fluid Pump Command Circuit – Voltage Below Normal or Shorted to Low Source
Posted by PerDiezel Solutions on
Lamp:Amber Reason:A short circuit to ground has been detected in the diesel exhaust fluid pump command circuit. Effect:Possible reduced engine performance. Circuit Description:The dosing unit relay provides a battery voltage supply to the diesel exhaust fluid dosing unit. The ECM supplies a signal to the dosing unit to control the diesel exhaust fluid output. This signal changes, based on the diesel exhaust fluid pressure being commanded. Component Location:The aftertreatment diesel exhaust fluid dosing unit location is original equipment manufacturer (OEM) dependent. Conditions for Running the Diagnostics:This diagnostic runs when the aftertreatment diesel exhaust fluid dosing unit is commanded OFF. Conditions...
