Service bulletin SB_686.1

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 U17F0 code only appears in DAVIE 4 after the engine has run after a software update. It does not activate a check engine light or cause any change to the engine performance. A Pierce module update is available that will ensure that this code will no longer appear.

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.
