Circuit DescriptionThe aftertreatment diesel particulate filter temperature sensor module is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment diesel partculate filter temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the J1939 data link. The aftertreatment diesel particulate filter temperature sensor module is used to measure the aftertreatment diesel oxidation catalyst intake temperature, aftertreatment diesel particulate filter intake temperature, and aftertreatment diesel particulate filter outlet temperature. The temperature probes are permanently attached to the aftertreatment diesel particulate filter temperature sensor module and...

Circuit DescriptionThe 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 of the aftertreatment system. Component LocationThe aftertreatment outlet NOx sensor location can vary...

Circuit DescriptionThe sensor supply 5 circuit of the engine control module (ECM) provides a 5 volt supply for the aftertreatment diesel particulate filter differential pressure sensor, remote accelerator, engine coolant level sensor, fan speed sensor, and the accelerator position sensor 2. Component LocationSensor Supply 5 is dedicated for the secondary accelerator pedal position sensor in the OEM wiring harness. Sensor supply 5 can also be used for other sensors in the OEM wiring harness. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running. Conditions for Setting the...

Circuit DescriptionThe aftertreatment diesel exhaust fluid tank heater keeps the diesel exhaust fluid from freezing in the diesel exhaust fluid tank. The tank heater consists of an electrically powered tank heater control valve which controls the flow of engine coolant to a heating coil inside the diesel exhaust fluid tank. The tank heater control valve opens to allow coolant to flow to the heating coil when heating is commanded, and closes when heating is no longer required. Component LocationThe diesel exhaust fluid tank heater control valve is located near the diesel exhaust fluid tank. Specific location will vary depending on...
