2005 LLY, no tune installed. With the truck running, when I plug my code reader scanner into the OBDII port, many of the dash lights start flashing/blinking/”service 4wd”/fuel gauge goes to E, but the truck will drive fine. I unplug the scanner and everything returns to normal.
If the scanner is plugged into the truck first, then I try to start the truck, the truck starts and dies immediately.
This same scanner used to work fine in this truck, and it still works fine in my dad’s 2005 LLY and in various other vehicles.
I’ve checked various fuses, harnesses, etc.
Any ideas?
