Hello and welcome to just answer and allowing me to assist you. I may ask questions so I can get a better picture so I can help you . This happens when you have a problem with the 4wd system communicating with the ECU.First thing is to check the vacuum hoses going to the actuator for any leaks,check the connectors at the diff lock solenoid and transfer case. I will include a chart that may help as well. If you require further assistance let me know.
