hello everyone

[cdatj2]

my sister inlaw just came up from colorado to idaho and the all wheel disabled message appeared, the fluid in the trasfercase was changed and tranny topped off but light still comes on after being on the interstate for a bit and only at 65 or better, no noises or other drivabilty problems and no other lights or problems, is this a emergency or a nussance type problem
