Have Truck Repair Questions? Ask an Expert
Hello! Thank you for choosing Just Answer! My name is ***** ***** I will gladly assist you with your question today. So fault code 2777:
2777PID: S390SPN: 3703FMI: 11/31LAMP: NoneSRT:
Particulate Trap Active Regeneration Inhibited Due to Inhibit Switch - Condition Exists. Regeneration of the diesel particulate filter has been prevented due to the permit switch being disabled.
None on performance.
Is the issue you are currently experiencing? Do you have Cummins Insight? If you do have Insight you can connect to the truck, go to Features and Parameters, under the Inhibit Switch option you should be able to "disable" or "enable" the inhibit switch. Please let me know if this option applies to your situation, if not I will assist further as needed. If this does answer your question, please take a moment to rate my service as we are not paid for our answers unless a rating is made. Thank you! I look forward to your response.
To add, under the inhibit switch enable/disable option you will want to disable the switch
Just wanting to touch base to see if you needed any further assistance with the current issue, please let me know, thank you!
Thank you for that information, are there any other fault codes present other than the 2777?
Ok, codes 3714 and 2777 are usually accompanied by other aftertreatment related codes, if no other codes are present and these two are active then I recommend the following to get to the bottom of this issue:
1. Has the aftertreatment been serviced recently? If so, perhaps the "reset all" procedure in insight was not performed, that is a good place to begin
2. Check the ECM calibration, if the calibration is not current then an update may be available with a revision to either code or to the scr or aftertreatment system, perform an ecm recal
If all of the above do not work to resolve the codes, verify that all sensors are connected properly to the aftertreatment system, usually this issue would throw other codes but you never know and it is worth it to not overlook it. The inhibit switch on the dash should not be engaged either, if you disable the switch in insight but press it physically then that could be an issue also. Sometimes it is the simple things! Please let me know how I can further assist if needed. Also please do not forget to rate my service for today. Thank you
