Cummins ISB4.5 CM2150 Fault Code: 3566 PID: SPN: 5394 FMI: 4 Aftertreatment Diesel Exhaust Fluid Dosing Valve – Voltage Below Normal or Shorted to Low Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid (DEF) dosing valve is controlled by the aftertreatment DEF controller. When the engine electronic control module (ECM) commands DEF dosing, the DEF controller 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 LocationThe 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 position will vary, based on the aftertreatment architecture and the original equipment manufacturer (OEM)....

Cummins ISB4.5 CM2150 Fault Code: 3569 (Airless) PID: SPN: 3362 FMI: 7 Aftertreatment Diesel Exhaust Fluid Dosing Unit Input Lines – Mechanical System Not Responding or Out of Adjustment.
Posted by PerDiezel Solutions on
Circuit DescriptionThe diesel exhaust fluid dosing unit lines are responsible for transporting diesel exhaust fluid between the dosing unit, dosing valve, and diesel exhaust fluid tank. Component LocationThere are three diesel exhaust fluid lines. One line is between the dosing unit and dosing valve, and the other two lines are between the dosing unit and diesel exhaust fluid tank. These lines can be partially hidden from view by the Selective Catalytic Reduction (SCR) system and other vehicle components. Line routing will vary, based on the aftertreatment architecture and OEM. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch...

Circuit DescriptionThe DEF dosing unit supplies DEF to the aftertreatment nozzle through the nozzle supply line. Component LocationThere are three DEF lines. One line is between the dosing unit and aftertreatment nozzle, and the other two lines are between the dosing unit and DEF tank. These lines can be partially hidden from view by the selective catalytic reduction (SCR) system and other vehicle components. Line routing will vary, based on aftertreatment architecture and the original equipment manufacturer (OEM). Conditions for Running the DiagnosticsThis diagnostic runs continuously while the SCR system is dosing DEF into the aftertreatment system. Conditions for Setting...
