C1405 Transfer case range sensor High
I also got this error code along with the flashing swaybar light. I live in Tucson and it turned out to be a pack rat that chewed the wire harness that connects to the transfer case range sensor located on the top of the transfer case. I pulled the connector and re-soldered the wires to fix it. Pretty easy fix since the sensor connector is just a 2 wire connection.
Hope that helps future readers
