Cummins ISB CM850 (2003-06) Fault Code: 2353 PID: SID 146 SPN: 2971 FMI: 6 Exhaust Gas Recirculation (EGR) valve control circuit – current above normal or grounded circuit. Excess current detected at the EGR valve motor output circuit.
The ECM monitors the current draw of this circuit. If the ECM detects excessive current for a calibrated period of time, it records this fault.
Possible causes:
1)EGR valve motor (+) or (-) leads shorted together in the engine harness, EGR valve motor, or ECM
2)Low EGR valve motor internal resistance.
Possible epairs:
1)Replace the EGR valve assembly.
2)Repair or replace the engine harness.
3)Replace the EGR valve assembly.
Cummins ISB CM850 (2003-06) Fault Code: 2352 PID: SID 146 SPN: 2791 FMI: 3 EGR Valve Control Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at the EGR valve motor circuit.
Cummins ISB CM850 (2003-06) Fault Code: 2351 PID: SID 146 SPN: 2791 FMI: 4 EGR Valve Control Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at the EGR valve motor circuit.
Cummins ISB CM850 (2003-06) Fault Code: 2349 PID: SID 146 SPN: 2791 FMI: 5 EGR Valve Control Circuit – Current Below Normal or Open Circuit. High voltage or open circuit detected at the EGR valve motor circuit.
Cummins ISB CM850 (2003-06) Fault Code: 2348 PID: 27 SPN: 27 FMI: 13 EGR valve failed automatic calibration procedure – out of calibration.
Cummins ISB CM850 (2003-06) Fault Code: 2347 (ISC) PID: SPN: 2790 FMI: 15 Turbocharger Compressor Outlet Air Temperature (Calculated) – Data Valid but Above Normal Range – least severe level.
Cummins ISB CM850 (2003-06) Fault Code: 2347 (ISB) PID: SID 151 SPN: 611 FMI: 15 Turbocharger compressor outlet temperature – data above normal. High turbocharger compressor outlet temperature has been calculated by the ECM.
