This is what is screwing up on my Rubi, the rear locker engaged by itself in 2WD last night.On a Rubicon, there is an electrical connection where the vehicle indicates to the lockers that the transfer case is in 4-wheel low., Limiting locker use to 4 low only.
It’s possible. @EBW, perform the instrument cluster self check. While it’s going through all the tests, make note of the last digits of the VIN that are displayed. Just to rule out a gauge cluster swap.Could something be haywire in this person's PCM?

With the key off, press and hold the trip meter while turning the key to the “on” position. Release the trip button. Self test will begin. Here’s a detailed description:I'm not familiar with that, is there a Youtube video or thread here that describes how to accomplish this ?
I’m not sure, but the little I’ve read there is programming that has to be done when new because the instrument cluster acts as the body control module also.Would a gauge cluster swap have anything to do with the transfer case acting wonky?

That actually makes sense due to the research I've done in regards to V8 swaps. I've heard that mentioned that the factory gauge cluster acts as a body control module.
I actually just found that out today when I was researching the gauge cluster/transfer case interface.
That's good info. I never would have even thought of this.
I thought you could just swap a gauge cluster straight in, but it sounds like you might have to program it after you plug the new one in.
Rubicon auto, lifted in June and worked fine until yesterday.Is it a manual and was it lifted recently ?
My Zone 4.25 lift came with a linkage relocation bracket and has been working fine for months. Just all of a sudden the 4wd indicator light is messed up. The Savoy cable mod is on my to do list, however. Savvy, stupid autocorrect!I don't know the details on the automatics but basically when you lift one and you have a stock linkage you're usually on the verge of not being able to get the vehicle into four wheel drive low... And by that I mean right on the verge.. because the lift has cocked the linkage and you're not getting the amount of throw that you need in order to engage the Rotator on the transfer case.
This is why it worked for a while but it only took a little bit of movement of the body or change in the way the suspension settled to cause you to lose what little throw you had... When the actuator goes into 4-wheel low it should go completely and solidly.
There is a rod with a 13 mm nut on the manual Jeeps on there transfer case linkage and it should be the same on the automatic... You want to loosen that nut and physically turn the actuator on the transfer case to get the Jeep into 4-wheel low and then tighten the nut all this needs to be done while the handle is in the very highest position.
This should give you four wheel low and it will work but if you will change to a Savvy shift cable you will never have any issues again pretty much.
Same issue, just fixed it last week. First problem was the 4wd position sensor on top of the transfer case. That also determines if you are in 4LO and allows shifting of the lockers. Do you have locker issues?2006 Rubicon, the 4 Wheel Dash Light
