Service bulletin SF637

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

Field Service Campaign for FCCC Viper Low Voltage Display. In a low voltage condition, the instrument panel (IP) display may not come on when turning on ignition leaving drivers without a functioning instrument panel. This would only occur at startup and the IP would function again if the key is cycled with normal voltage.

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.
