Fault code
J1939 SPN
J1939 FMI
3714 Engine protection torque derate - Condition
1569 exists. Critical fault codes related to engine
31 operation are active.
Engine speed at idle - Data valid but below
3715
normal operating range - Moderately severe
188
level. The engine speed at idle has exceeded
16
the governed idle speed.
Engine speed at idle - Data valid but below
3716
normal operational range - Moderately severe
188
level. Engine is not maintaining the governed
18
idle speed.
Aftertreatment outlet NOx sensor - Out of
3717
calibration. A calibration mismatch between the
3226
aftertreatment outlet NOx sensor and the ECM
13
has been detected.
Aftertreatment intake NOx - Out of calibration. A
3718
c a l i b r a t i o n m i s m a t c h b e t w e e n t h e
3216
aftertreatment intake NOx sensor and the ECM
13
has been detected.
Battery 1 voltage - Data valid but below normal
3724
operating range - Least severe level.
168
Low voltage to the EGR valve device driver has
17
been detected.
3725 Aftertreatment Intake NOx sensor - Abnormal
3216 rate of change. The aftertreatment intake NOx
10 sensor reading is not valid.
High pressure common rail fuel pressure relief
3727 valve - Mechanical system not responding or
5571 out of adjustment. The fuel rail high-pressure
7 relief valve has opened at a lower than
expected pressure.
Engine starter mode overcrank protection -
3737
Condition exists. The starter motor has been
1675
temporarily disabled in order to prevent starter
31
damage.
High pressure common rail fuel pressure relief
3741 valve - Data valid but above normal operational
5571 range - Most severe level. The fuel rail pressure
0 relief valve has opened due to high fuel rail
pressure.
3749 Aftertreatment outlet NOx sensor - Data not
3226 rational - Drifted high. An offset in the outlet
20 NOx sensor reading has been detected.
3838 Estimated engine parasitic losses - Percent
2978 torque - Abnormal update rate. A loss of
9 communication has been detected.
Cruise control disable command - Abnormal
3843 update rate. No communication or an invalid
5603 data transfer rate has been detected on the
9 J1939 data link between the ECM and the
cruise control.
