J1939 FMI
EGR Valve control circuit - Current above
2353
normal or grounded circuit. A short circuit to
2791
ground has been detected in the EGR valve
6
motor circuit.
Fuel filter differential pressure - Data valid but
2372
above normal operational range - Moderately
95
severe level. Excessive fuel flow restriction to
16
the high pressure fuel pump has been detected.
Exhaust gas pressure sensor circuit - Voltage
2373
above normal or shorted to high source. High
1209
signal voltage detected at the exhaust gas
3
pressure circuit.
Exhaust gas pressure sensor circuit - Voltage
2374
below normal or shorted to low source. Low
1209
signal voltage detected at the exhaust gas
4
pressure circuit.
Exhaust gas recirculation temperature sensor
2375
circuit - Voltage above normal or shorted to high
412
source. High signal voltage detected at EGR
3
temperature circuit.
Exhaust gas recirculation temperature sensor
2376
circuit - Voltage below normal or shorted to low
412
source. Low signal voltage detected at EGR
4
temperature circuit.
2377 Fan control circuit - Voltage above normal, or
647 shorted to high source. Open circuit or high
3 voltage detected at the fan control circuit.
VGT Actuator driver circuit (motor) - Mechanical
2387 system not responding or out of adjustment.
641 The smar t VGT controller has detected
7 incorrect stop limits, or the VGT is unable to
move to the closed position.
2398 Ambient air temperature - Data erratic,
171 intermittent, or incorrect. The ambient air
2 temperature sensor is reading an erratic value.
2448 Coolant level - Data valid but below normal
111 operational range - Least severe level. Low
17 engine coolant level detected.
2449 Vgt actuator controller - Out of calibration.
641 The VGT actuator has been installed incorrectly.
13
Engine crankshaft speed/position - Data valid
2468
but above normal operating range - Moderately
102
severe level. The engine speed has exceeded a
3
critical limit.
2554 E x h a u s t g a s p r e s s u r e - D a t a e r ra t i c,
1209 intermittent or incorrect. The exhaust gas
2 pressure sensor is reading an erratic value.
