Help - 06 Rubi Front Locker Light Flashing

[Jeepin335]

So, there I was sitting in my driveway, had not even touched the 4x4 shifter and my Front Locker light starts flashing...and will not go out? Has anyone run into this problem before? I've played with it a little...it will go into 4 low and both front and rear will lock and both lights go solid... however, once disengaged, the front light continues to flash...even with the ignition off the light continues flashing, but more rapidly and I get the warning tone (like if you have left your headlights on). Help please....suggestions???? Thanks

Sounds like it thinks its locked when it shouldn't be.

There's a plug down by the front diff for the sensor (not the vac line looking hose).

unplug that and see if the flashing goes away.

Fairly sure there are 2 signals to the rubi that the front diff is locked. One is from the locker pumps, it either grounds or VCCs one of the wires when its done pumping and at pressure. The other is the switch that's in the diff.

If that switch is messed up in the diff, the diff won't spin right and it won't lock at all, so I doubt that's it.
