Service 4WD Error

[Adrianp89]

Truck will not shift out of 2wd. I tried putting truck in neutral and going from Lo to Hi to Auto but no luck. Going to disconnect the battery overnight. Next step is to look at the actuator. Anyone have a good way to test the actuator? Should I just get a scan tool? Error doesn’t show unless I try to go into 4WD and then goes away

Try disconnecting the actuator and using brake cleaner to clean the contacts. A number of us have had this error due to used oil dripping down during an oil change and seeping down the harness into the connector.

Yeah that could definitely be an issue for me. I gotta do an oil change soon so I’ll try that after I’m done. Thanks!
