Fault code
J1939 SPN
J1939 FMI
Aftertreatment diesel particulate filter outlet
temperature sensor circuit - Voltage below
3321
normal or shorted to low source. Low signal
3246
voltage detected at the aftertreatment diesel
4
particulate filter outlet temperature sensor
circuit.
Aftertreatment diesel particulate filter outlet
3322 temperature - Data erratic, intermittent, or
3246 incorrect. The aftertreatment diesel particulate
2 filter outlet temperature is not changing with
engine operating conditions.
SAE J1939 Multiplexed accelerator pedal or
lever sensor system - Abnormal update rate.
3326
The ECM expected infor mation from a
91
multiplexed accelerator pedal or lever sensor
9
but did not receive it soon enough or did not
receive it at all.
Transmission output shaft speed - Abnormal
3328 update rate. No communication or an invalid
191 data transfer rate has been detected on the
9 J1939 data link between the ECM and the
transmission output shaft speed sensor.
Engine exhaust gas recirculation cooler
3342 efficiency - Data valid but below normal
4752 operating range - Moderately severe level. The
18 EGR cooler is not cooling the recirculated
exhaust gas sufficiently.
Engine charge-air cooler efficiency - Data valid
3343
but below normal operating range - Moderately
5285
severe level. The engine charge air cooler is
18
not cooling the intake air flow sufficiently.
3361 Intake manifold 1 pressure - Abnormal rate of
102 change. The VGT position reading is stuck.
10
3366 Coolant level - Data valid but below normal
111 operating range - Moderately severe level. Very
18 low engine coolant level detected.
Roll over protection brake control active -
3374
Condition exists. The ECM received a message
1818
from the anti-lock braking (ABS) controller,
31
inhibiting cruise control operation.
After treatment diesel par ticulate filter
3375 regeneration too frequent - Condition exists.
5397 The system has detected the need for an active
31 regeneration has occurred too soon following
the last active regeneration.
After treatment diesel par ticulate filter
3376 incomplete regeneration - Condition exists. The
5319 system has detected that the aftertreatment
31 diesel particulate filter differential pressure is
too high following an active regeneration.
