no power at datalink port

....

 

Not sure where my post went lol.

Anyway youre busting my chops that sucks. I just want to turn off the bendix its dangerous as hell and terrible to use if anyone is actually on the freeway. Would unplugging the radar just kill the cruise altogether?

On the alaram I've tried checking it. Im getting and error that says this program.has errors that need to be corrected before it saves"programs" its at the bottom.of the screen in like a blue footer. also this error too. they may be related.

 

Got it squared

 

I had the same problem with my 2020 Freightliner SD 122 after Safelite auto glass sliced through my ELD cable and I got a replacement there was no power, finally found the fuse it’s located in the panel behind the driver seat in the B post you open the door and lift the cover off of the fuse box that controls the rear of the truck there is a 10 fuse labeled DIAG/SP5 That fuse was blown as soon as I replaced it with another 10 amp fuse problem fixed.

 

FYI: For those with this issue Western Star and Freightliner have a 10A fuse labeled Dataport, BAT. Likely at F25 in the fuse box in the dash.
