Service bulletin V261401 2036531

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

Technical Bulletin (Ad Blue Warning Light XXX Miles to No Restart Displayed): Selective Catalytic Reduction (SCR) system diagnostic too sensitive. The product solution for this issue was a software update. After updating the ECM software, the Ad Blue warning lamp may still be illuminated. If the Ad Blue warning lamp is still illuminated with the message ?No engine start possible in XXX mi.?, a Selective Catalytic Reduction (SCR) efficiency test must be run in order to clear the message. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.
