Service bulletin AOS-13-14

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

We are aware that some dealers are installing online updates without completing saved diagnostic sessions first. This results in any saved diagnostic sessions becoming incompatible with the updated software version(s), and it is not possible to resume sessions and subsequently transmit GFF logs for warranty purposes.

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.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
