    My service 4wd just popped up on my driver information center yesterday. Anyone else had this before or know what the possibilities are that are setting this off? thanks

    Normally it's either the (if you have it) push-button module that needs fixing/replacing or the actuator on the transfer case. Seems to be the general things wrong with the S4WD light.

    Do a quick search on the forums and you will find a plethora of matches to that same problem. I'm sure others will chime in with a little more help than this. :)

    Good luck with your 4WD issue!
