Engine injector metering rail 1 cranking
4691 pressure - Data valid but below normal
5585 operating range - Moderately severe level. The
18 fuel rail pressure during cranking is too low for
the engine to start.
4713 Engine fuel injection quantity error for multiple
5357 cylinders - Condition exists. A malfunction of all
31 fuel injectors has been detected.
Engine fuel leakage - Data valid but above
4726
normal operating range - Moderately severe
1239
level. Fuel rail pressure decay has been
16
detected.
Injector metering rail 1 pressure - Data valid but
4727
above normal operating range - Least severe
157
level. A self pumping condition has been
15
detected in the fuel system.
4731 Aftertreatment diesel exhaust fluid tank
3031 temperature sensor - Out of calibration.
13 The received datalink message was not valid.
4732 Aftertreatment diesel exhaust fluid tank level
1761 sensor - Out of calibration. The received
13 datalink message was not valid.
Aftertreatment 1 diesel exhaust fluid tank level
4739 sensor - Root cause not known.
1761 An unknown error has been detected with the
11 aftertreatment diesel exhaust fluid tank level
sensor.
Aftertreatment 1 diesel exhaust fluid tank level
4769
sensor - Abnormal rate of change.
1761
A valid diesel exhaust fluid tank level reading
10
has NOT been received.

4865
above normal, or shorted to high source. High
6303
signal voltage detected at the engine coolant
3
level 2 circuit.
Engine coolant level 2 sensor circuit - Voltage
4866
below normal, or shorted to low source. Low
6303
signal voltage detected at the engine coolant
4
level 2 circuit.
4956 Engine variable geometry turbo (VGT) software
520750 - Out of calibration. VGT software does not
13 match application.
4957 Engine variable geometry turbo (VGT) software
520750 - Condition exists. The VGT actuator and ECM
31 software is not compatible.
