J1939 Code Description Effect and Action
4360-4
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : Voltage
Below Normal The ECM detects the following conditions:
The signal voltage from the SCR inlet temperature sensor
is less than 0.2 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 Below
Normal" will be displayed next to the status for “SCR Inlet
Temperature" on the electronic service tool.
Sensor Signal (Analog, Passive) - Test
4360-16
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : High -
moderate severity (2) The aftertreatment Selective Catalytic Reduction (SCR)
catalyst intake gas temperature sensor has detected that
the SCR intake temperature is above the normal operating
range.
SCR Catalyst Has Incorrect Inlet Temperature
4360-17
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : Low - least
severe (1) This diagnostic code is only applicable to engines that have
a Diesel Particulate Filter (DPF).
The Electronic Control Module (ECM) detects that the SCR
catalyst intake temperature is below the acceptable range.
The code is logged.
SCR Catalyst Has Incorrect Inlet Temperature
4360-18
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : Low -
moderate severity (2) The aftertreatment SCR catalyst intake gas temperature
sensor has detected that the SCR intake temperature is far
below the normal operating range.
SCR Catalyst Has Incorrect Inlet Temperature
4360-20
Aftertreatment #1 SCR Catalyst
Intake Gas Temperature : Data
Drifted High The ECM detects the following conditions:
The SCR inlet temperature sensor has probably failed in
range.
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 “Data Drifted High‘ will
be displayed next to the status for “SCR Inlet Temperature"
on the electronic service tool.
Sensor Signal (Analog, Passive) - Test
4364-2
Aftertreatment #1 SCR Catalyst
Conversion Effi ciency : Erratic,
Intermittent, or Incorrect The engine out NOx level is not responding as expected.
The code is logged.
NOx Sensor - Test
4364-18
Aftertreatment #1 SCR Catalyst
Conversion Effi ciency : Low -
moderate severity (2) The SCR System is not able to reduce NOx in the exhaust
system.
NOx Conversion Is Low
4374-5
Aftertreatment #1 DEF/AdBlue®
Pump #1 Motor Speed : Current
Below Normal This code indicates low current to the DEF pump motor.
The code is logged.
DEF/AdBlue® Pump - Test
4374-6
Aftertreatment #1 DEF/AdBlue®
Pump #1 Motor Speed : Current
Above Normal This code indicates high current to the DEF pump motor.
The code is logged.
DEF/AdBlue® Pump - Test
4377-12
Aftertreatment #1 Outlet NH3 :
Failure The data received from the ammonia (NH3) sensor is out
of range.
The code is logged.
The warning lamp is illuminated.
Sensor (Data Link Type) - Test
