Description

Cummins ISB6.7 CM2350 (2013-17) Fault Code: 4151 PID: SPN: 5742 FMI: 9 Aftertreatment Diesel Particulate Filter Temperature Sensor Module- Abnormal Update Rate

Circuit Description
The aftertreatment diesel particulate filter temperature sensor module is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment diesel partculate filter temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the J1939 data link. The aftertreatment diesel particulate filter temperature sensor module is used to measure the aftertreatment diesel oxidation catalyst intake temperature, aftertreatment diesel particulate filter intake temperature, and aftertreatment diesel particulate filter outlet temperature. The temperature probes are permanently attached to the aftertreatment diesel particulate filter temperature sensor module and can not be replaced individually.

Component Location
The aftertreatment diesel particulate filter temperature sensor module is mounted on the aftertreatment diesel particulate filter.

Conditions for Running the Diagnostics
This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running.

Conditions for Setting the Fault Codes
The Engine Control Module (ECM) detected a loss of communication with the aftertreatment diesel particulate filter temperature sensor module.

Action Taken When the Fault Code is Active
1)The ECM illuminates the amber CHECK ENGINE lamp and/or the Malfunction Indicator Lamp (MIL) immediately when the diagnostic runs and fails.
2)Active and stationary regeneration of the diesel particulate filter will be disabled.
3)Diesel exhaust fluid injection into the aftertreatment system is disabled.
4)Engine torque will be reduced if the engine is operated for an extended period of time with this fault active.

Conditions for Clearing the Fault Code
1)To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute.
2)The fault code status displayed by INSITE? electronic service tool will change to INACTIVE immediately after the diagnostic runs and passes.
3)The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.
4)For On-Board Diagnostics (OBD) engines, the ECM will extinguish the Malfunction Indicator Lamp (MIL) after three consecutive trips where the diagnostic runs and passes.
5)The Reset All Faults command in INSITE? electronic service tool can be used to clear active and inactive faults, as well as extinguish the MIL for OBD applications.

Possible causes:
1) Low battery voltage supply
2) Incorrect terminating resistance of the SAE J1939 datalink circuit
3) Incorrect Battery System Voltage setting in INSITE
4) Incorrect sensor for the application (12 VDC versus 24 VDC)
