Yep, it's a 911! problem since I've got a front locker and it is staying engaged on hard pavement.... I did a search, got a gazillion hits, and couldn't find an answer. This is really strange.
When I engage 4wd, the tcase may or may not decide to engage for a minute or so, or maybe until I get up to a higher speed. Then once engaged, it will not turn off: the magnetic clutch stays locked. The 4wd lights do not start flashing and it doesn't show an error. Here's the strange thing.... I have the "Brown Wire Mod" and can turn off the switch (which should physically turn off power to the tcase clutch) and it still stays engaged even when no power via the brown wire is keeping the magnetic clutch turned on! At first I thought that I fried my switch but it's okay, and I have removed it and left the brown wire unconnected where I cut into it, so that confirms that the tcase stays engaged even when the brown wire is cut.
It gets stranger..... I can turn off my engine and restart and it is still engaged even with no power through the brown wire and after the engine had been turned off! The ONLY way for me to get it to let go is to unplug the wiring harness with all of the wires going into the side of the tcase (and then of course I get the flashing 4wd lights ) to remove all input into the tcase. Then if I replug it in again, reconnect the brown wire, and later on try to use 4wd, it will once again decide when it wants to engage - maybe right then, maybe sometime soon, maybe a little later on - and then once engaged it will again refuse to let go and stay engaged until I crawl under the vehicle and unplug the wiring harness.
What is going on? Bad GEM or TOD relay? How is it staying engaged even when the brown wire is not sending it power, even after turning the engine off?
