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 diesel exhaust fluid line heaters are used to defrost and/or prevent freezing of the diesel exhaust fluid lines. Component LocationThe aftertreatment diesel exhaust fluid line heater 1 is located on the supply line between the diesel exhaust fluid dosing unit and the diesel exhaust fluid dosing valve. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and line heating is commanded ON. Conditions for Setting the Fault CodesThe Engine Control Module (ECM) detected an open in the line heater circuit. Action Taken When the Fault Code is ActiveThe ECM illuminates the...

Circuit DescriptionThe aftertreatment diesel exhaust fluid line heaters are used to defrost and/or prevent freezing of the diesel exhaust fluid lines. Component LocationThe aftertreatment diesel exhaust fluid line heater 2 is located on the return line between the diesel exhaust fluid dosing unit and diesel exhaust fluid tank. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and line heating is commanded ON. Conditions for Setting the Fault CodesThe Engine Control Module (ECM) detected an open in the line heater circuit. Action Taken When the Fault Code is ActiveThe ECM illuminates the amber CHECK...

Circuit DescriptionThe injector solenoid valves control fueling quantity and injection timing. The engine control module (ECM) energizes the solenoid by closing a high-side and a low-side switch. Each injector circuit has a dedicated low-side switch that completes the circuit path to ground inside the ECM. Component LocationThe engine harness connects the ECM to the pass-through connector(s) that are located in the rocker housing. Internal injector harnesses are located under the valve cover and connect the injectors to the engine harness at the pass-through connector(s). Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting...
