Hi, My name is***** will be glad to help. We can follow up as needed on here. Professionals are not employees of the site but users of the site and help on here as time allows depending on their daily schedule. This code occurs when a regulatory fault is ignored and a derate condition exists. It is normally the result of other fault codes. I would check the complete fault code history as there should be other fault codes. If there is not, it is very likely that you have a software calibration problem that would require having your software reprogrammed and updated to reset everything back to factory settings with the most current updates.

For 2011 models, this code sets when the vehicle has been driven for 30 miles while a code is present for the DEF tank level, DEF metering valve, DEF pump, NOx sensors, Blocked DEF line, DEF quality, NOx efficiency, SCR harness and/or SCR sensor.

For 2010 models, this code sets when the vehicle has been driven for 10 hours or 500 miles while a code is present for the DEF tank level, DEF metering valve, DEF pump, NOx sensors, Blocked DEF line, DEF quality, NOx efficiency, SCR harness and/or SCR sensor.

SPN 5246/FMI 15

Show/Hide Checkboxes

  1. Connect DiagnosticLink® . Go to step 2.
  2. Check for other emission-related fault codes. Are there any Selective Catalyst Reduction (SCR) or Diesel Particulate Filter (DPF) related fault codes present?
    1. Yes; diagnose and repair the emission-related fault codes first. Verify repair.
    2. No; perform the Selective Catalyst Reduction (SCR) efficiency test or high idle regeneration. Use DiagnosticLink to clear the code.

I hope you find this information helpful. Reply back with the results of these checks if any further help is needed. It is a pleasure to help anyway I can.
