That means that the 4 low has been selected but the shift motor is unable to complete the the command. On my rig it was a bad shift motor, it would do 4 HI but didn’t have the torque to make the 4 LO shift. A new motor and a relearn and it works. But you should have the entire system checked, you could have a underlying transfer case or wiring issue.
