Swaybar Disconnect Not Available

[Rubycon50]

2018 Jeep JLU Rubicon 3.6L AT, Electronic SwayBar

Having issues with an error code on my dash which says Swaybar Disconnect Not Available. I have done some troubleshooting:

1. Put it in 4 high and pressed the pressed the sawy bar button.
2. Made sure the jeep was level and tried again, also stretched out the suspension to see if it would work.
3. Checked the fuse called 'Smartbar', It's intact and seated properly
4. Removed the sway bar and the gearing and sliders inside are clean and well lubricated, looks new inside
5. Separated the electronic module and hooked it back up to the wiring, pressed the sway bar button, nothing changes. Also depressed the electronic sensor on the motor while pressing the sway bar button.

I do have an aftermarket bumper and i noticed when I flex the sway bar the wiring that runs to it rubs up against the edge of the bumper. The wiring looks intact and I don't see any obvious damage. I tried wiggling the wire and still nothing. The motor looks well sealed so hopefully no water intrusion.

Any ideas? I'm not much of a electrical trouble shooter but I do have a bit of diagnostic equipment, multimeter, circuit tester and power probe.

Any help much appreciated. Don't want to go down a rabbit hole of replacing expensive unavailable parts for no reason if possible.

Sway bar only disconnects in 4wd low. You stated you were trying while in 4wd high. Try in 4low

Thanks, tried that too.

Thanks, tried that too.

And you are getting signal to the motor? I assume you’ve checked the connector on the wire harness to see if it’s getting signal? That would help narrow down if it’s the motor or the jeeps wiring or computer.

I have not tested the connector on the wiring harness yet. Not sure if I know how to do that.

What ended up happening? Mine is doing the same thing from the factory.

Adam, I think you need a Jeep. The VW and the Tesla don't have the disconnect.

2019 did this today. Anyone have luck?

There can be a lot of reasons for this to happen. You need a decent scan tool to work on these things properly.
