circuit frequency - Abnormal frequency or pulse
2623
width or period. The accelerator pedal position
8
sensor reading is out of range.
After treatment diesel par ticulate filter
4151 temperature sensor module - Abnormal update
5742 rate. No communications on the J1939 data link
9 between the ECM and the aftertreatment diesel
particulate filter temperature sensor module.
Aftertreatment selective catalytic reduction

5743 rate. No communications on the J1939 data link
9 between the ECM and the aftertreatment SCR
temperature sensor module.
Aftertreatment 1 diesel exhaust fluid dosing unit
4155 heater relay - Voltage above normal, or shorted
5746 to high source. High signal voltage detected at
3 the aftertreatment diesel exhaust fluid dosing
unit heater relay circuit.
Aftertreatment 1 diesel exhaust fluid dosing unit
4156 heater relay - Voltage below normal, or shorted
5746 to low source. Low signal voltage detected at
4 the aftertreatment diesel exhaust fluid dosing
unit heater relay circuit.
Aftertreatment diesel exhaust fluid return valve -
4157
Mechanical system not responding or out of
4376
adjustment. A stuck aftertreatment diesel
7
exhaust fluid return valve has been detected.
