Front Locker Coil/Solenoid Actuator Dead - Sources?

[THAW]

My front locker sensor is the issue, not rear. I've had a couple JLs with tazers, back in 2020 it wasn't an option either. Put one in my 2018, no front only option back then, or now for that matter.

Can you verify the button you programmed? Interest to see if it actually works.

Sorry about confusing your front/rear (though it didn't make any appreciable difference in my statement).

Here are some screenshots of the Tazer JL Mini instructions I have saved on my phone:

I've verified the mapped button "works", I'll try to physically verify the state of the lockers.

Yeah it says it's a mode but I've never had that option work in either JL I've owned. I should have been more clear...Mode....Option, patato.....tomato..lol. sorry bout that.

If it says it's a mode and it doesn't work, that option isn't available is how I interpreted that in my brain...lol

All good info! Cheers!

If you're going to isolate the locker wiring from the DTCM, remove/bypass the sensors in the axle housing and run the locker coil actuator directly to the pass-through connector. Then run your own wiring to your switches. No signal fooling resistors, etc..

I saw your Bronco actuator solution...so what you're suggesting is basically the same as using one of theirs. Broncos done have the sensor...that's smart! I knew they had m210s but didn't even think about if their lockers were different. Or figured they were too different really due to IFS.

Good write up by the way!

Thinking about it some more, the JL coil connector just plugs into the sensor lead that then plugs into the pass-through connector. The 2 power wires for the coil just pass-through the sensor lead. So, there's not a benefit to removing the sensor that I can see. The pass-through connector on the outside of the axle has 4 pins. 2 of them are for the coil power (don't ask me which 2, it's been too long) and essentially go directly to the coil.

I jacked up the axles and confirmed the Tazer feature works, front locker only.

The only question remaining is why "front/" is no longer included with "rear/front+rear" in the current Tazer button mapping instructions. Was the feature removed from the latest firmware or is it just a typo?

After I get my sensor bypassed, I will give it another try. When ever I pushed up both lockers locked.

Also just got a Lasfit red switch replacement that has some interesting potential. connects to the CANBUS, replaces factory red switches with theirs. redistributes current to isolate each locker with out having to run the two MOPAR harnesses and rewire switches on the dash.....the cost is about the same and way less crap getting rewired.

Latest tazer manual.....attached. no mention of 'front only" mode/option. only to disable one or the other or both for axle swaps which would remove all of the components front the truck anyway. When I disabled my front to to see if I could still use it, it did not work either.

I hope this is helping or helps someone in the future. As JLs age out, my 2020 is out of warranty, I think a lot more people will start doing self mods land not just pay $200 for $10 in parts and a little math. I just want my Jeep to do what I want it to with out every dash light blinking....LOL

Oh, now I finally understand what you meant by "not with the Rubicon switches". You're correct, with the Tazer the front locker button is mapped to the steering wheel (the dash locker switches can't be used to engage it). The dash locker indicator light ("FRONT+REAR") illuminates and the dash locker "OFF" button disables it though.

Can you provide a link to the switches you mentioned? Are they "Aux" switches or replacement locker switches?

According to this post, the Lasfit locker switches with CAN bus connector use the same logic as the factory switches; that is, the front locker can only be engaged with the rear.

[The next post in the same thread has a video showing how it works.]

The hope is the Tazer will take care of that. Gunna contact them and see.

Jeep JL/JT locker sensor bypass solved. I also found them on ALIbaba but I had to buy 50 and shipping was stupid.

Doesn’t Tazer have a “lock front” shortcut through button mapping that allows the front locker only to be locked?

Never mind…I skipped your post already covering this

Just read through the LasFit manual and you can isolate F/R lockers by:
- turning the ignition to run, do not start truck
- immediately press and hold the R locker button.
- you will hear a beep then the switch es are independent.

This setting stays until changed from how it reads.

(LO-JPS03, LO-JPS04) The Front and Rear locker switch can work in two different modes. Default = Locker mode. When in locker mode, the F & R locker switch only operates when the Jeep is in 4L. This safety feature prevents drivers from accidentally engaging the differential and causes mechanical damage to the Jeep. Standalone mode.
- I think I can handle not engaging lockers when I shouldn't. Used to have to get out and lock hubs, I can handle not pushing a switch. I will only be using the red switches for lockers and swaybar (for now). wont be accidentally engaging lockers to turn on my RGB blinky light display...LOL

When in standalone mode, the F & R locker switch work independently as a normal on/off switch.
- We shall see if this function works the way I think it will.

Also ordered a Z-LCK-OEM bypass deal for $17.99. Worth taking apart and seeing how it works. I'll probably do a write up for each one separately so people can save some money. If they have the skills to solder a couple wires together, seal, and wrap back into the harness with some auto tape, its a win.

Goal at the end:
No dash light warnings
Use factory harness
Bypass locker sensors
have independent F/R locker switches
Oh and install my 4.56s, RCVs and Chromo rears, build 2.5 ton steering, beef up the cage, but thats a different thread!

The way I read this functionality, the two locker buttons operate the factory lockers "Locker Mode" OR operate as auxiliary switches (not connected to the factory lockers) "Standalone Mode". I could be wrong, but...

"The two buttons on the left of the red switch can not only control the front and rear differential locks like the factory one. It can be also set as switches to control other lights and devices. Amazingly, with our full kit you can control up to 8 devices."

I would think a steering wheel button mapped to the Tazer "Front Locker" function would still work (for factory lockers) with the Lasfit panel, though.
