Official summary
The MIL is on. DTCs are stored in the ECM. No relevant component or electrical problems are found when Guided Fault Finding (GFF) is run on the stored fault codes. The current ECM software does not accurately model soot loading at idle, which may trigger a false DPF overload warning.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
