Service bulletin VVT-12-27

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

Service Information (VAS-PC & ODIS Service ? Uninstall and Reinstall Overview): When ODIS Service is installed on VAS diagnostic devices with VAS-PC diagnostic software, a number of application and diagnostic database files are shared. As a result, whenever ODIS Service or VAS-PC diagnostic software requires uninstallation and reinstallation to resolve software malfunctions, or the diagnostic device?s Windows XP® operating system requires a full recovery, a specific sequence must be followed in each case. This document informs of the specific sequence.
