Just received a 10+ inch snowfall. Took the TB out for some fun. Turned the 4WD Switch and nothing. Noticed no lights, no noise activating. Checked the #8 fuse which appeared good and reinserted. Worried it may be the TCCM. Did a quick "Search" found an update to pull the #8 fuse and wait 30 sec to get out of "Sleep Mode". Followed steps, Started the TB, Lights are on, everything works as expected !! Nice easy no $$ fix !!!
