Hello, I'm trying to get into engineering mode on my 24 so I can adjust my very inaccurate mpg readout. Been doing the procedure where you hold ok for 5 sec, turn key to run, and it should come up on screen. What I get is a brief flash of the engineering screen followed by the stupid seat belt status display. When I push ok for the seat belts, the engineering screen is gone.
I've tried to do this with my seat belt fastened, all belts fastened, me not even sitting in truck, etc, and it...
Can't get into engineering mode!
