Service bulletin M1654

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

SERVICE BULLETIN M1654: DTII MODULE REPLACE MENU CHANGE. PURPOSE: This bulletin informs dealer technicians that there is a new menu item in Digital Technician II (DT II). DT II now has a stand alone Module Replace menu inside of Vehicle Setup. This will allow you to program the factory settings, for the connected vehicle, to the Electronic Control Module (ECM), Body Control Module (BCM) and Infotainment Control Unit (IFCU) (if equipped) in a single menu. Initial Release. 8/7/2024.
