Using my SGII I have it show fWT, EOT, FSS, and BSTm The problem I keep having is at times the XGuages aren't working, I check the settings and everything is correct but they don't show anything. Could there be a problem with my SGII. Most times everything is fine, but once in awhile they don't show anything.
I've always had the same issues. At times I have to turn the truck off, let the SGII go to sleep, restart the truck and let the SG come back on by itself. It also happens if I unplug the SGII while the truck is running. I can't tell you what it is but mine does the same thing.
on a pretty regular basis I will notice the sg is not displaying....
since I have it mounted right in front of the gear display on the dash, I just loosen the plug and reinsert and it always boots up then... (DO THIS WHEN AT RED LITE !)
Check the go to sleep settings in the menu scince I changed mine to RPMS the only problem Iv had is it not automatically turning on when I start the truck... for some reason I think Iv noticed it messes up when I plug or unplug stuff into the cig lighter adapter (not the upper one the lower one) its ran off the same fuse as the OBDII reader...
just a thought is your cell phone pluged in and charging?
I keep the GPS pluged up, a few hours after the problem, I let the truck sit and the SGII go to sleep, then do a KOEO, the SGII didn't automatically turn on, so I powered it on and the xguages worked, and since then it has been working fine.
