Service bulletin LI27.19-P-056151

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.

With an unfavorable sensor position and high rpms, the sensor may deliver incorrect rpm values and the transmission control unit may detect overspeeding. Owing to the software application, the control unit is not reset in the case of implausible messages.
