Service bulletin TSB 25-2119

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

Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to the software in the PCM.

The document
