This is something weird. I reset the Maint. by with holding the Trip A down, turning the ignition key to on and waiting for the dashes to go to out. But now every time I turn off the truck both Trip A and Trip B odo's get reset to zero! What have I done? Anybody have any idea how to go back to normal? Thanks P.S., had this over in the Electrical forum with no takers. Boo.
