Errors stab sys, traction control, serve 4wd

Those 3 systems are intertwined, so a problem in one affects the others. Let the dealer look at it, it's most likely one of two issues:
1)xfer case encoder motor(moves the shift fork)
2)brake pedal switch misadjusted(there's two of them)
As long as the dealer follows diag charts correctly(always start with lowest trouble code numerically) they'll get it fixed fine.
