Service bulletin PIT6396
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
This PI communicates an issue with a SES MIL with DTC P2535, P12A6, P10DA and/or C111B maybe set after replacing the fuel pump driver module. Engineering is working on a fix, but in the meantime, dealers are to install a diode.
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.
