I’m in a 2014 freighliner, and it has a samsara ELD.
My boss will take our trucks to local pickups and preload our trailers for us before we arrive to the yard.
It’s under the air miles for ELD requirement so he just unplugs them, and has for over a year, no issues, but suddenly my ELD is giving a power and engine synchronization malfunction.
I recently had my batteries replaced, and as far as I know that shouldn’t suddenly cause this. His other trucks do not give the malfunctions, but they’re all Volvos.
Any idea as to why this is happening now?
