PACCAR PX-9 CM2350 (2013-17) Fault Code:3558 PID: SPN:3361 FMI:3 Aftertreatment 1 Diesel Exhaust Fluid Dosing Unit – Voltage Above Normal or Shorted to High Source
Posted by Diezel Solutions on
Reason:Aftertreatment Diesel Exhaust Fluid Dosing Unit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at the aftertreatment diesel exhaust fluid dosing unit. 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,...

PACCAR PX-9 CM2350 (2013-17) Fault Code:3567 PID: SPN:5394 FMI:5 Aftertreatment 1 Diesel Exhaust Fluid Dosing Valve 1 Circuit – Current Below Normal or Open Circuit
Posted by Diezel Solutions on
Reason:Aftertreatment Diesel Exhaust Fluid Dosing Valve – Current Below Normal or Open Circuit. 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...
