Service bulletin TSB250225

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 Technical Service Bulletin describes the verification and resolution steps for the mobile generator control module calibration which may contain a defect, resulting in the Selective Catalytic Reduction (SCR) Inlet Temperature parameter value reading not being visible on the HMI display and a delay of approximately 49 minutes to display the correct DEF Tank level reading following a calibration download to the control module.

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.
