Service bulletin LI91.10-P-049799

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 presence of a quiescent current can have several causes. These are not always recognized and lead to an increased number of OK components being removed. Possible Hall sensor faults or normalization faults can exist which can be eliminated without replacing the control unit.

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.
