There should be a code in the OBC, go to a place like Autozone and have the code read free. Post the P# back here for more info.

The message could mean any number of faults.

From a malfunctioning 4x4 dash push button module to low fluid in the transfer case.

I wouldn’t ignore the message as this MAY be a trivial thing but it could also be serious. It’s your wallet.
