Service bulletin A011520 2040489-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
