I was pulling into a parking lot today and as I pulled into a parking spot a light on the dash appeared stating ''service fwd'. Im assuming it means four wheel drive but nothing appears wrong. After I started the truck when I left the light was off and didnt appear on the 15 mile trip home. Anyone else experience this as far as I know the only thing it could be related to is the electronic shift controller. I will see if it comes back on during this weeks commute.
