Drive train control module.. same as Transfer case control module?

[XtremeRetard]

So.. long story, short.
You can't turn off lockers in a Rubicon because the drive train control module has lockers built in as part of its config.

However.. If you match your transfer case with another platform that does not have lockers by default. EG. Sahara, which you can option with fulltime rocktrack and no lockers..
Then you can swap the DTCM which if I am correct, is the Transfer case control module and thereby disable the lockers..

This is needed because I have swapped axles in my Rubicon..

Anyway, bottom line.. Who knows the part number for a Sahara control module with full time rocktrack awd with no lockers?

Looks like the control modules are under $100 used off Ebay. Im hoping to find the right one and give it a go..

Sahara has Selec-Trac, not the Rock-Trac.
Rock-Trac is Rubicon only - it's the lower geared version of the Selec-Trac.
Lockers are controlled by a switch on the dash - what do you mean you can't turn them off?
I put our Rubicon in Full time 4 wheel drive and it doesn't engage lockers.

1st, From what I know about how our Jeep computer systems work... this may or may not work as intended.... until your jeep goes in for updates. Then your original VIN configuration will be reapplied and your new module will go back the way your last one was.

2nd, yes you can disable the lockers on the Rubicon... With either the JScan app or the JL Tazer. Both have ways of disabling this feature from the computers so you can change axles or just differentials to something else.

Sorry, wrong. Both Tazer and JScan will say they have disabled the lockers, but you will still get DTC and check lights on the dash from codes.

I know because I've just done it and spoken to the JScan dude.. He told me it's because of the DTCM hard coding for the platform.. Unless you wish to prove me wrong, which I'm happy for you to do. Let me know what settings to set. Ive tried both JScan and Tazer. Neither work on the rubicon.

Also yeah, maybe I mean the Selec Track fulltime 4wd from the sahara, not the rocktrack.

I’m pretty sure 100s of people on this forum have done axle swaps in their rubicons successfully with a tazer or something similar.

I am researching DTCMs for another reason and I don’t think there is a DTCM configuration that suits your needs. There are no JL with a 4:1 t-case 241 without lockers.

But I am not sure that matters. Yes you could by a Dtcm for a vehicle without lockers. But the ratio would not be correct. But I think you can change the ratio with JScan?

That would work I think.

Very interested in the solution. I had always thought there was a solution, that would appease the idiot lights, for either a non-OEM E-locker or mechanical differential.

I had thought that the z-automotive jumper harness did this. I think the BCM is looking for the load from the locker sensor, which I believe is a coil.

Ok update.

While both devices still leave dtc codes logged. Tazer seems to change the severity of the codes, so as not to light the dash.

Unlike jscan which leaves the dash lit.

Just finalizing what I did and will confirm after extended testing. But initial results are not to use jscan and use tazer instead to disable lockers.

That's a bit sad as unmarried tazer will restore the errors.

Did you ever figure this out. I’m in the same boat. I have disconnected both front and rear lockers because the stupid sensors just kept failing and I couldn’t ever use my lockers.
The dealers won’t repair them because I regeared so I’m SOL.
I have hardwired the Mopar harness to my aux switches. I have used JScan to delete the lockers with no luck so I tried the taser to delete the lockers and had no luck. I just get the service four-wheel-drive error on the dash because of the DTCM mismatch error. I can delete the DTCM and then I don’t have any codes. But I’m not sure what happens and don’t want to drive the Jeep with it turned off until I figure out what it actually does. Thanks.

I think a phone call to Wranglerfix.com might yield some insight.

Yep. JSCAN does not work. Mr JSCAN himself told it would not work directly.

Tazer will do this because it is permanently connected so addresses the issues in realtime.

So back out all the JSCAN changes. Then using Tazer do the same disable process. Initially on key on you will see the same dash lights come up briefly, then go away as Tazer takes them out.

I prefer JSCAN for stuff likel FAD and Gear changes as its permanent and does not need to be connected. But for the Lockers on a Rubicon your only solution is Tazer I believe.
