# 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 id: 10119984
- Published by NHTSA: 2017\-10\-21

## 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.
