Hi my name is***** with me while I pull up your fault code.
Possible causes of this fault code include:
Fault Code: 3582PID:SPN: 4364FMI: 18LAMP: AmberSRT:
Aftertreatment SCR Catalyst Conversion Efficiency - Data Valid But Below Normal Operating Range - Moderately Severe Level. NOx conversion across the SCR catalyst is too low.
None on performance.
If none of the above are found as a cause have the software updated and check for the most current software updates. Let me know
Only Cummins authorized dealers will be allowed access to the updates so you will have to bring it to a dealer for the updates.
Should be a flat fee for reflash and updates.
Hi Steve, I posted the potential causes of this code. I have a shop and have yet to have anything get turned away unfixed. In cases where a module needs to get sent out for a reflash I do so. However before doing that I eliminate all other possible causes. So lets start with this list below. Let me know the status of your checks for one of the ten trucks since it may or may not be the same reason for this fault on all ten trucks. If the below potentials are 100% ruled out not the cause then go for the software update. This is all part of troubleshooting this fault. Let me know your test results for each of the below.
Thanks for the update. Excessive soot or carbon buildup, leaks/restrictions will cause the SCR to fail.
