In my 09 Titan Pro 4x today I notice the Diff light in the bottom right of the dash flashing today. It was randomly flashing to no pattern to it whatsoever like it was a short in the light. After awhile it went off and the ABS and SLIP light came on. I have a OBF reader and no codes came back. My 4H drive does seem to work. I used it today while the lights where on. Does anyone have any insight on this issue?
