Hey every one, check 4WD light came on about a week ago, tried resetting it by holding all 3 buttons on with it off then for 30 seconds on reds a few times. Nothing changed so I took it to a mechanic they said they couldn't scan it & to take it to an auto electrician so I took it to another mechanic it he sent me to 4wd shop who then told me only holden can fix this problem? Anyone had this problem before & know what I could be up for
