4 wheel drive not engaging

[StephenF]

Tried my 4x4 the other day and got the service 4x4 as lights kept blinking. Had a buddy of mine check the plugs as we read the issues with oil getting in them for the actuator ….cleaned everything and put his computer to clear the codes to see if it changed anything and the system says it needs a user name and password to clear the codes…..is this mopars way of forcing you to go to the dealer ? Any help would be appreciative…
