Service bulletin T7276

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

This Temporary Repair Practice is being issued to recalibrate the engine control module (ECM) on certain B6.7, L9, X12 and X15 engines that have fault codes 3749 and/or 6463 that cannot be cleared with a service tool. This field action authorizes certified service locations to update the ECM calibration.

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.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
