So I had the dreaded locker service light show up today. I remembered reading about it here as soon as I seen it. Sure s@#t I looked it up once I got to work. Just like I remembered full on axel swap for the fix.

I have a few problems with this.

#1. 1,754 out of warranty @37,754 miles on her. #2 I have the Rock Krawler Pro X cradle welded to my rear axle. I will be ordering the Z harness and hope to god that fixes the issue. Wish me luck.

Oh man I hope it doesn't come to that. I am not familiar with this. Is there a thread about it? Would like to understand the issue. Cheaper to just swap the locker itself if it is bad?

There are multiple threads about this issue. From what I gather there is a sensor that is known to go bad. Cant just buy the sensor, can't just buy the lockers. FCA has been swapping the axels out for people with this problem. Zautomotive in conjunction with Americas Most Wanted 4X4 has a plug in solution for $179. I'll start there and progress if needed.

Reminds me of the wifes $900 windshield Chrysler quoted. It has the $.01 light sensor bracket attached lol.
We opted for after market and made it work for ~$200.

The locker sensor issue struck today...3500 miles from home. What's the consensus on continuing to drive with it blinking? It seems like I can still lock and unlock in 4LO.

Ordered the z automotive solution and hoping they can get it to me this week before I head back across the country.

From what I gather the lockers will still work while just blinking. I never had blinking just service lockers. I would not worry about driving it home. God luck my friend.

Thanks. I tried using Jscan to hide the lockers so at least it wouldn't be stuck trying to unlock and potentially burn out something, but that triggered the Serv 4wd light. That seemed worse than just blinking locker light. I'm going to roll with it and hope the zlocker adapter gets here before I take off.

AMW 4x4 quickly shipped me the OEM locker correction cable. $179+shipping to bypass a $5 sensor.

I thought it was strange when I pulled the locker plug and there was diff fluid in it, but maybe that's normal??

Plugged everything in and works as expected. The plug into the diff doesn't lock in place so going to wrap it with some tape to keep it from coming out. Zip tie it up and we should be good.

Jeep Gladiator Service locker light came on PXL_20210630_220947075

Bummer.

Suggestion I am sure you have already tried...is it indicating front vs rear and is the adapter on the right one? Or maybe both sensors have failed? Clearing all codes with an OBD tool and seeing if it pops again? The correction adapter could always be bad too?

Good luck!

So now it sounds like my front locker is parshalay engaged or something. It is making quite the clunking noise. Not sure what is going on with it. I have not tried to lock in the lockers scene winter. I guess that explains why my Z harness did not do the trick of shutting the light off.

You are out of the bumper-to-bumper warranty. However, the powertrain warranty goes to 60,000 miles and I'm pretty sure the axles are part of the powertrain. Not sure if the powertrain warranty would be voided by your mods though.
