Jeep JLUR 2020
Hello, I have a Jeep JLUR 2020, I changed the gears to 4.88 around 4 months ago and my Jeep is running perfectly without any issues. Today while driving on the highway the rear diff locker got engaged automatically, I thought I pressed it by mistake so I turned it off and luckily it did, after few minutes the rear diff locker got engaged again and this time when I turned it off, the diff lock light keeps on blinking on the switch and on the dashboard and its not unlocking, has it happened to anyone before and is there a solution for it?

The computer shouldn’t allow Lock unless in 4L - even if there’s a short somewhere calling for it. Did you remove that safety feature, flash the ECU, using a piggyback unit, etc?

No I didn’t, it was showing that its engaged on 2H while driving 100km/h approx 60mph, and when I turned it off it kept on blinking but didn’t disengage.

Or a false signal caused by that infamous sensor, made out of unobtainium, located in the diff?

I read a lot about this sensor, does the Z Locker OEM fix this problem? Or there are other solutions? As the axles is regeared so warranty will not cover this fault I presume.

Currently, the sensor isn't available without the rest of the axle assembly attached to it. And yes, I'd imagine most dealers would use the regearing as an excuse to void your warranty or at least refuse to do the work. Even if they did it, it would be the same part destined to bring you back to where you are now.

The zautomotive harness is your best bet, if it is in fact the sensor that is causing your issue.

The problem is deeper. If the dealer does support the claim under warranty, the solution as someone mentioned is a complete axle swap. He’d lose the regearing. That wiring harness from Z automotive is cheap enough it’s worth attempting.

What I'm curious about, is whether or not its actually physically locking or just a false read by an oil shorted position sensor.

If it isn't actually locking, I'd feel confident in the Z harness sorting it out. If it is, than it is indeed a deeper issue.

I guess the other two threads with hundreds of comments didn't cover this issue. FFS.
