if you disconnect both battery cables for 5 minutes then touch the 2 battery cables together for 1 minute then reconnect both to the battery will it still show that message and will the 4WD switch from 2HI to 4HI and back to 2 HI ?
if it still will not work make sure fuse # 44 and # 69 are good in the under hood fuse box
if those 2 fuses are good the odds are that the encoder motor on the drivers side of the transfer case is bad
pull off the motor and if you can shift the transfer case by hand into the gears then replacing the encoder motor should correct this problem you are having
