Overview
| CODE | REASON | EFFECT |
| Fault Code: 3582 PID: SPN: 4364 FMI: 1/18 LAMP: Amber SRT: |
NOx conversion across the SCR catalyst is too low.
|
Possible reduced engine performance. |
Circuit Description
The engine control module (ECM) monitors the NOx concentration in the engine’s exhaust gases using an aftertreatment intake NOx sensor and an aftertreatment outlet NOx sensor. By comparing these two values, the ECM is able to determine the conversion efficiency of the SCR catalyst and dosing system.
Component Location
The SCR catalyst is located in the vehicle’s exhaust system, after the diesel particulate filter and decomposition tube.
Conditions for Running the Diagnostics
This diagnostic has to meet specific engine and aftertreatment conditions to run and complete.
Conditions for Setting the Fault Codes
The Engine Control Module (ECM) detected the NOx conversion across the SCR catalyst was less than expected.
Action Taken When the Fault Code is Active
- The ECM illuminates the amber CHECK ENGINE lamp and/or the malfunction indicator lamp (MIL) immediately when the diagnostic runs and fails.
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
- It is necessary to use the «Reset All Faults» command in the recommended Cummins® electronic service tool or equivalent to clear this fault and extinguish the amber CHECK ENGINE lamp and/or Malfunction Indicator Lamp (MIL).
