What are the Tier 4 fault codes for Cummins?
Cummins Tier 4 Fault Codes Fault Code J1939 SPN J1939 FMI Lamp J1939 SPN Description Cummins Description QSB 6.7 QSL 9 QSX 15 QSB 4.5 QSF 3.8 QSG12 111 629 12 Red Controller #1 Engine Control Module Critical Internal Failure – Bad intelligent device or component XXXXXX 115 612 2 Red System Diagnostic Code #2
What does Cummins Engine code 4364.18 mean?
They are what Cummins calls “intelligent devices”, which basically means they they are there own little ECM and transmit information to the main ECU over the data link. It’s possible that a NOx sensor could fail in a way that wont set a code for the NOx sensor, but I have yet to see that happen.
Is there a charge for SPN 4364.18?
Yes, let employers and TruckersReport text me with new opportunities, job alerts and other career information to the number I provided. There is no charge for this service, but standard message and data rates may apply. SPN 4364, FMI 18 is SCR conversion efficiency low.
What’s the code on my Cummins ISX 15 check engine light?
I got a 2013 Peterbilt with a Cummins isx 15. For the last two weeks I’ve been getting a check engine light with code spn 157 FMI18 Fuel rail pressure, code reads fuel rail pressure valid but below average. Truck sat for two weeks over holidays and I replaced both fuel filters and the fuel rail pressure sensor.
What is the SPN code for the fuel filter?
SPN Code: SPN Name: SPN Description: 16: Engine Fuel Filter Differential Pressure (see also SPN 1382) Differential pressure measured across the fuel filter located between the fuel tank and the supply pump. See SPN 1382 and Figures SPN16_A & SPN16_B. 18: Engine Fuel Pressure (Extended Range) 19: Engine Oil Pressure (Extended Range) 20
Where to find SPN code for 16 engine?
SPN codes description SPN Code SPN Name SPN Description 16 Engine Fuel Filter Differential Pressure (see also SPN 1382) Differential pressure measured across the fuel filter located between the fuel tank and the supply pump. See SPN 1382 and Figures SPN16_A & SPN16_B.
What is the fault code for SPN 639?
SPN 639 – FMI 9 (Fault Code 285) SPN639 FMI9 ISB, ISC and ISL with CM2150 – SAE J1939 Multiplexing Circuit
When does a Cummins fault code go inactive?
3712 – Aftertreatment SCR Operator Inducement- Data Valid but Above Normal Operational Range- Most Severe Level Conditions for Clearing the Fault Code This fault code will go inactive once all other active fault codes have been addressed. Refer to the appropriate fault code troubleshooting tree.
What are the ISL codes for Cummins ECM?
122 Intake Manifold Pressure Sensor Circuit – Voltage Above Normal or Shorted to High Source 123 Intake Manifold Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source 124 Intake Manifold One Pressure – Data Valid but Above Normal Operational Range – Moderately Severe Level
What are the fault codes for Cummins oil pressure sensor?
A low signal voltage or an open circuit is detected in the oil pressure sensor circuit. The ECM determines that the oil pressure sensor signal voltage is less than 0.25 VDC for more than 16 seconds. ISF 2.8, ISF 3.8, ISB, ISC, ISL, ISLe , ISDe , QSB 3.3 A high signal voltage or an open circuit is detected in the coolant temperature sensor circuit.
How does a fault code work on a Cummins Engine?
Fault codes are Cummins way of letting you know that your engine has a problem. Every sensor and circuit on your engine has a certain expected reading and voltage signal. These signals are monitored constantly by the Cummins ECM.
What does the FMI number on a SPN mean?
The SPN is usually accompanied by a FMI number, which is “failure mode indicator”, or basically how it is faulty. The ECM can detect the sensor circuit shorted, open, temp too high or temp not changing at all. So you are still down to either a sensor problem or a problem with the wiring.
What is the SPN for exhaust gas temp 3?
I find SPN 3245 which is “suspect parameter number”. 3245 is for the #3 exhaust temp sensor. There are about 5 or 6 different faults though. The SPN is usually accompanied by a FMI number, which is “failure mode indicator”, or basically how it is faulty.
