5-49
J1939 Code
Description
Effect and Action
4334-3
Aftertreatment #1 DEF/AdBlue® #1
Pressure (absolute) : Voltage Above
Normal
There is excessive voltage on the signal wire between the
Diesel Exhaust Fluid Controller (DCU) and the DEF pump.
or
There is an open circuit on the supply, signal, or return wire.
The code is logged.
DEF/AdBlue® Pump Pressure Sensor - Test
4334-4
Aftertreatment #1 DEF/AdBlue® #1
Pressure (absolute) : Voltage Below
Normal
There is low voltage on the signal wire between the DCU
and the DEF pump pressure sensor.
The code is logged.
DEF/AdBlue® Pump Pressure Sensor - Test
4334-16
Aftertreatment #1 DEF/AdBlue® #1
Pressure (absolute) : High - moderate
severity (2)
The DCIU detects that the DEF pump pressure is above
the acceptable range.
The code is logged.
DEF/AdBlue® Pressure Is High
4334-18
Aftertreatment #1 DEF/AdBlue® #1
Pressure (absolute) : Low - moderate
severity (2)
Diesel Exhaust Fluid (DEF) system pressure dropped
below the acceptable threshold during dosing.
DEF/AdBlue® Pressure Is Low
4334-21
Aftertreatment #1 DEF/AdBlue® #1
Pressure (absolute) : Data Drifted
Low
The signal from the DEF pump pressure sensor is below -
10 kPa (- 1.5 psi) when the DEF system is not primed.
Sensor Supply - Test
4354-5
Aftertreatment #1 DEF/AdBlue® Line
Heater #1 : Current Below Normal
This code indicates that there is a fault in the #1 (suction)
line heater circuit that is probably an open circuit.
DEF/AdBlue® Line Heater - Test
4354-6
Aftertreatment #1 DEF/AdBlue® Line
Heater #1 : Current Above Normal
This code indicates that there is a fault in the #1 (suction)
line heater circuit that is probably a short circuit.
DEF/AdBlue® Line Heater - Test
4355-5
Aftertreatment #1 DEF/AdBlue® Line
Heater #2 : Current Below Normal
This code indicates that there is a fault in the #2 (delivery)
line heater circuit that is probably an open circuit.
DEF/AdBlue® Line Heater - Test
4355-6
Aftertreatment #1 DEF/AdBlue® Line
Heater #2 : Current Above Normal
This code indicates that there is a fault in the #2 (delivery)
line heater circuit that is probably a short circuit.
DEF/AdBlue® Line Heater - Test
4356-5
Aftertreatment #1 DEF/AdBlue® Line
Heater #3 : Current Below Normal
This code indicates that there is a fault in the #3 (return)
line heater circuit that is probably an open circuit.
DEF/AdBlue® Line Heater - Test
4356-6
Aftertreatment #1 DEF/AdBlue® Line
Heater #3 : Current Above Normal
This code indicates that there is a fault in the #3 (return)
line heater circuit that is probably a short circuit.
DEF/AdBlue® Line Heater - Test
4360-3
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : Voltage
Above Normal
The ECM detects the following conditions:
The signal voltage from the SCR inlet temperature sensor
is greater than 4.95 VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds.
The diagnostic code will be logged if the engine has been
operating for more than 7 minutes.
“Voltage Above Normal" will be displayed next to the status
for “SCR Inlet Temperature" on the electronic service tool.
Sensor Signal (Analog, Passive) - Test
侍#
Some fault codes are not applied to this machine.
