E-disconnect Sway Bar code

I need some help figuring this out as it might be the caused by or the cause of some electrical gremlin in my jeep.

Sway bar light is flashing and i pulled the code :
U1159 code-- lost communication with sway bar

I have previously taken apart the sway bar connector and cleaned it as well as put di-electric grease on it to prevent any issue with water when this initially started happening.
after that the light continued to flash but the e-disconnect feature still worked as the motor would engage and disengage but now it doesnt.

also from time to time my 730n will loose power or the screen will act as if it was shorting out. I have removed and cleaned off the power lug to the TIPM to be sure that it was well connected.

I'm actually having troubles with starting since this started happening too. How did you go about fixing it?

i unplugged it. mine hasent worked in years. my RK lift came with disconnects anyway. i used my superchips trail dash to make the sway bar light stop blinking. now i have to get out of the jeep like a common jeeper and disconnect manually.

What caused the short? Who knows. Probably dirt and debris got inside the controller, plug or receptacle.

If you leave the smartbar unplugged do you have any problems starting? If not, leave the plug disconnected, wrap it well in self-sealing rubber tape. Is the smartbar locked or unlocked? If locked just throw on some quick disconnects and be done with it. Put a piece of electrical tape over the blinkie dash light if it bothers you.

If unplugging the connector doesn't solve the starting problems then the plug itself is shorted. One solution is to replace the wiring harness. Another solution is just to cut off the connector, dip the ends in liquid insulation a few times then, when dry, wrap with rubber tape.

My smartbar failed twice. After the second time I just said the hell with it, unplugged and taped-up the connector and let it be.

I believe when that when the bar fails it automatically locks. also i know its locked as i put one tire over a large rock and the whole jeep titled rather than just the one tire travel upwards.

how will cutting the connector and putting liquid insulation trick the tipm into thinking its working properly? if it shorted then wouldnt the wires be toast too?
