Cummins X15 CM2350 X116B Performance Series (2018 & Newer) Fault Code: 4282 PID: SPN: 5298 FMI: 11/31 Aftertreatment Diesel Oxidation Catalyst Conversion Efficiency – Condition Exists

Lamp:
Amber

Reason:
The temperature increase across the aftertreatment diesel oxidation catalyst is lower than expected.

Effect:
1. None on performance.
2. Active and stationary regeneration of the diesel particulate filter will be disabled.

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

Component Location:
The aftertreatment diesel oxidation catalyst is located in the exhaust system. The location of the catalyst can vary, depending on the Original Equipment Manufacturer (OEM).

Conditions for Running the Diagnostics:
This diagnostic has to meet specific engine and aftertreatment conditions to run and complete.

Conditions for Setting the Fault Code:
The Engine Control Module (ECM) calculated the DOC efficiency was less than a calibratable value.

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.

Conditions for Clearing the Fault Code:
It is necessary to use the “reset all faults” command in the recommended diagnostic tool or equivalent to clear this fault and extinguish the amber check engine lamp and/or Malfunction Indicator Lamp (MIL).

Shop Talk:
Possible causes of this fault code include:
1. A malfunctioning diesel oxidation catalyst.
2. Malfunctioning fuel injectors.
