Hey Guys,

Here is the formal Dodge T21 recall doc ( 5 pages) issued and updated this past June 2018. On page 3,...It does state that in some instances, after the recall is done,...there will be an ongoing issue with the van not completely powering down (instrument back light and EGR valve?) and that in those instances, replacing the instrument panel is the remedy.

Anyone have the Freightliner or Mercedes Equivalent of this document. I would like to forward a copy of it to my Local Freightliner dealer who so far is telling me that I need an ECU and It will be at my expense.

Vic, wondering if this doc should be posted at the beginning of the thread with your update notes?

In the PDF there is a nice outline/description of the ECM orderly shutdown timing circuit operation. It again reinforces that the FB#1 is not just a Fuse Box, it is a module.

Feel free to add any similar descriptions for ECM operation or other clarifying information to this thread.
