OBD2 port issue?
Soooo was driving (2005 Excursion 6.0) along the interstate and I use my DASHDAQ for PID info. All was well but as I was almost at my destination I decided to check for codes. My normal glow plug 2 circuit code was the only thing that showed up. Sweet! Cleared it and went back to the gauges screen…and the only gauges that showed any values were coolant temp, trans temp, and battery voltage. EGT still showed but that’s not through the OBD port. No oil temp, no boost, FICM sync, crank sync, FICM power, anything else. Just blank on those PID’s. I’m guessing I blew a fuse somehow? But the DASHDAQ still powers up so I’m confused. The fuel gauge still works in the instrument cluster, so…I dunno 😊

Oh, also now the glow plug circuit 2 code isn’t showing up, so it’s not reading codes either

Have you rebooted? My Bluetooth adapter loses communication frequently while driving but comes back after un plugging/replugging.

Mine is a wired connection. I’ve unplugged it and plugged it back in with same result. It’s getting power and SOME signals from the port, so…🤷‍♂️

Just to confirm, have you plugged it into another truck?

I have had the SGII stall like that also.
what I found works was to unplug turn
the truck off. Then after a few minutes
Plug back in and restart.

Yep, both ways. I've also had TorquePro flip out and tell me my truck was 1000 degrees or some crazy number. That'll take your eyes off the road.

I too have had this issue at times. I found that unplugging the obd dongle, reinstalling it and rebooting the device solves my issue.

Well, hopefully I’m good. The batteries are out of the truck for a couple weeks while I’m on a trip
