Rear E-Locker
 

I've searched thru a few threads but with no luck. Has anyone successfully bypassed the lo-4wd control of the rear locker?

Re: Rear E-Locker
 

I'm no mechanic, so I am not sure why you want to by pass this, but I have a switch above the radio, where the 4hi lock, 4Low Lock etc buttons are. One is to engage/disengage the rear locker. And as far as I know, the rear locker is only available in the 5speed manual trans.

Re: Rear E-Locker
 

The locker is availabe with either transmission and the bypass he's referring to is so that it can be engaged in 4Hi-Lock. From the factory, you can only engage the rear locker when in 4Lo and it automatically disengages if you go over 20mph, IIRC.

There was some talk about this on here before. But I haven't seen anyone post that they have successfully bypassed it in the H3 yet.

Re: Rear E-Locker
 

Right on, there are plenty of times that I'd like the rear locker locked in 4-HI, dune riding, mud running, snow.... Anyone had any success?

Re: Rear E-Locker
 

I have not done this but the whole car runs on a 12-Vdc system. Just find the wire that goes to the e-locker and tap with a volt meter and turn it off and on and then hook up a switch. that should do it. give it a try and then let me know if it works.

Re: Rear E-Locker
 

What's 12V DC have to do with it. If it was a 6 volt system it would work the same, or a new 42 Volt system?

Yes, there is a way to bypass it and it requires more than one wire, or you will light up the DIC and set codes.

Re: Rear E-Locker
 

f5fstop, do you have more info than that? I sure would like to work around this limitation.

Re: Rear E-Locker
 

Don't really want to interject here, but...

With the full time 4WD, and the traction control system, in the situations you describe, I just don't understand why you would need it?

Re: Rear E-Locker
 

Don't believe you would need it at speeds above 20 mph. The locker is supposed to be used for low speed applications; thus the 20 mph unlock. It might cause damage to the rear locker, which from my experience reading forums, means the person will remove the bypass and hit GM for the warranty.

We already have enough legitimate hits on warranty for the front axle...:clapping: and that is GM's fault.


So, even though I know how, I won't say how.

Re: Rear E-Locker
 

Too bad. The guys with a Jeep Rubicon figured it out and gladly share the info on how to. Seems like a valid reason for wanting to be locked in 4Hi IMHO.

Re: Rear E-Locker
 

Are they Jeep / DC employees?

Re: Rear E-Locker
 

The e-locker is controlled by the transfer case shift control module. This module monitors both the control and return voltages from the e-locker actuator and if they are incorrect DTC-C0388 is set and SERVICE 4WD is displayed. The control module also has a free wheeling diode to accomodate the e-locker's actuator coil's inductance. The e-locker's coil normal resistance is between 2.2 and 4.3 ohms.

Re: Rear E-Locker
 

I'm sure some were in the beginning. But now it is so common that aftermarket companies are offering kits. DC stated that they did not want to offer it as an option due to liability reasons (i.e. soccer mom munching rear diff in mall parking lot because she hit button accidentally) just like f5fstop stated above.

My point is that it (should) be an easy fix for somebody to figure out and the reasons stated for wanting to do it are sound. I completely understand why f5fstop doesn't want to publisize how to do it and I wasn't giving him crap. I just said it was too bad that there wasn't a quick fix out there as the original poster's reasons for wanting to do it seemed logical to me. I'm sure somebody will eventually post how to do it. If you're stupid enough to do the fix and then munch your locker, then I agree you shouldn't claim it under warranty. But, just because GM (or Jeep) doesn't offer it that way from stock is no reason to discourage somebody from doing it IMHO.

Geez, you guys are sure quick to jump somebody's ass if they don't follow the norm like sheep around here!:popcorn:

Re: Rear E-Locker
 

Ya think???

I simply stated that there are two other systems that would cover the needed traction in the situations you described.

How is that jumping your ass?

Hummers are more sophisticated vehicles. Comparing them to an outdated redneck system the likes of which Jeep uses is just well.....dumb. They are different. Period.

:popcorn::popcorn:

Re: Rear E-Locker
 

Yeah, I think.

Actually, I wasn't refering to your reply. But, you jumping in kinda proves my point.

It is funny in that I wasn't comparing apples to oranges. I agreed with the original poster that you should be able to bypass the system and that his reasons for wanting to seem valid. The fact remains that even though "Hummers are more sophisticated vehicles", there should be a way to do it. And if the guy wants to, he'll find way. I bought a Lux/Adventure over the Rubi. I'm one of you guys. I just don't share in the elitist attitudes that stock vehicles (no matter how "sophisticated" they are) should remain stock because thats how our lord god Hummer wanted them to be. If there are improvements to be had by tinkering under the hood in the effort of better off-roading, I'm all for it. But, as stated, I was not giving f5 attitude for not giving it up. He is a valuable asset to this board and has helped me out. I would not want him to jeopordize his job over a questionable mod. (Least of all for somebody else instead of me :D.)

You guys are a trip. I suppose that if I wanted to crank on my torsion bars a couple of turns to run bigger than stock tires, you'd poo-poo it because it isn't how it came from the factory? Give me a break.

You need to see how some of you long timers come across sometimes. Holy crap!

Re: Rear E-Locker
 

Just because you can ...doesn't mean you should:p

Re: Rear E-Locker
 

Oh and I run 35's with 5 turns, kicks ass on the Rubicon:excited:

Re: Rear E-Locker
 

My next mod. Going with 35" BFG/MT's. Was going to try 2.5 turns first. And, Moab is a couple hours from me.:jump:

Re: Rear E-Locker
 

So does that mean the Jeep guys are "cooler" than we are??

And you still have not address the need. Why when you have Traction Control and Stabilitrac?
