Fault code
J1939 SPN
J1939 FMI
Reason
Effect (only when fault code is active)
2963
110
15
Engine coolant temperature - Data valid but
above normal operational range - Least severe
level. Engine coolant temperature is above the
engine protection warning limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
Engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red STOP lamps starts flashing.
2964
105
15
Intake manifold 1 temperature - Data valid but
above normal operational range - Least severe
level. Intake manifold air temperature signal
indicates intake manifold air temperature is
above engine protection warning limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
Engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red STOP lamps starts flashing.
2973
102
2
Intake manifold 1 pressure - Data erratic,
intermittent, or incorrect. The intake manifold
pressure sensor is reading an erratic value.
Possible reduced engine performance.
2976
3361
2
Aftertreatment diesel exhaust fluid dosing unit
temperature - Data erratic, intermittent, or
incorrect. An internal error has been detected in
the aftertreatment diesel exhaust fluid dosing
unit.
Possible reduced engine performance.
3133
3610
3
Aftertreatment diesel particulate filter outlet
pressure sensor circuit - Voltage above normal,
or shorted to high source. High signal voltage
detected at the aftertreatment diesel particulate
filter outlet pressure sensor circuit.
Possible reduced engine performance.
3134
3610
4
Aftertreatment diesel particulate filter outlet
pressure sensor circuit - Voltage below normal,
or shorted to low source. Low signal voltage
detected at the aftertreatment diesel particulate
filter outlet pressure sensor circuit.
Possible reduced engine performance.
3135
3610
2
Aftertreatment diesel particulate filter outlet
pressure - Data erratic, intermittent or incorrect.
The aftertreatment diesel particulate filter outlet
pressure sensor is reading an erratic value at
initial key ON or during engine operation.
Possible reduced engine performance.
3146
4363
3
Aftertreatment SCR outlet temperature sensor
circuit - Voltage above normal or shorted to high
source. High signal voltage detected at the
SCR outlet temperature sensor circuit.
Possible reduced engine performance.
3147
4363
4
Aftertreatment SCR outlet temperature sensor
circuit - Voltage below normal or shorted to low
source. Low signal voltage detected at the
SCR outlet temperature sensor circuit.
Possible reduced engine performance.
3148
4363
2
Aftertreatment SCR outlet temperature sensor -
Data erratic, intermittent, or incorrect. The SCR
outlet temperature sensor is not changing with
engine operating conditions.
Possible reduced engine performance.
3151
4794
31
Aftertreatment SCR catalyst system missing -
Condition exists. The aftertreatment SCR
catalyst in the exhaust system is not present.
Possible reduced engine performance.
