The information center for my T-Case reads "Full-Time", "Part-Time", & "Lo" to let me know what mode my T-Case is in. However, when I'm in 4Lo the information center reads "Part-Time"? I am sure that 4Lo is engaged & I understand that 4Lo is Part-Time, but when should "Lo" be highlighted?

No matter what gear my T-Case is engaged in, the info. center never higlights "Lo", could the bulb be blown or am I confused on something here?

do you have the 242 transfer case - 2HI, 4HI (part-time) 4HI (full-time), Neutral, 4LO.

the reason I ask is because I do not know of a transfer case on jeeps with just 4HI PT, 4HI FT, and 4LO

231 - 2HI, 4HI PT, N, 4LO

249 - 4HI (fulltime), N, 4LO

ok, explain to us how you are trying to engage 4lo. a lot of people think it is in 4lo when it's not.

93 JGC - manual says to place stick all the way down to 4LO while jeep in motion at about 5mph, and tranny gear in neutral. No mention to engage it afterwards. If this is wrong what is the right procedure?

are you from a foreign country?

OK try this, come to a complete stop, place tranny in neutral, then pull straight back on the TC Lever without pausing in Neutral. then place tranny back into gear

are you from a foreign country?

WTF do you mean?

I do have the 242 T-Case & when I engage 4Lo I do the following:

1. Place the tranny in neutral
2. Pull the T-Case lever all the way back to 4Lo without pausing
3. Place the tranny back into gear (just like dksob81 states above)

Once I let off the brake, the Jeep begins to move forward slowly (telling me that 4Lo is engaged). However, the diagram will read "Part-Time" but "LO" never illuminates!

If anyone is confused, my question is about the electronic T-Case diagram, the one that highlights "Part-Time", "Full-Time", & "LO" in the color green!

....telling me that 4Lo is engaged).

This was my problem before, since you'll never know that fact without putting the jeep up the hoist, which I did and saw all four wheels moving.

For some reason, my 4LO light doesn't illuminate. Only the part time light comes on. I first thought it was the lightbulb, but replaced it with a good one.

Well Joed, now I know that I'm not the only one with this minor issue!

It's funny because just to the right of my Jeep diagram (the one that highlights the wheels green) there is an image of what I describe as a "battery with an X in the middle". The image looks like it should illuminate as well, but I have no idea when it should illuminate.

I posted something on here before to see if anyone knew what this image was for, because it's not even mentioned in the manual?

I have a 94 GC and here's what the lights mean:
"2 wheel" is normal (reer wheel drive)
"Part time" means 4wd, and it says "Part Time" to remind you that you shouldn't use this on dry pavement because the wheels all spin together, so the car will shake a bit while going slowly around corners.
I don't know if I have a "part time Lo" light - I just know it's in part time low because it takes a real conscious effort to pull the shifter all the way into 4WD low.
As far as the battery light with an "x" through it, I think that means someone stole your battery! (just kidding - I don't think this is really a light - just part of the cover template for the 4WD lights).

Thanks for the input Jeepforever. I understand what the lights mean, I was just curious as to why "LO" never illuminates!

The manual states that "LO" will illuminate when engaged on Quadra-Trac systems, but I guess it's not suppose to illuminate for Selec-Trac.

I seem tp have the same prob. I checked mine once before and illuminated "lo" now it is not, I was wondering if anyone else was haveing this problem.
even though it is not illuminated is it still in "4lo"

I believe that the diagram of the jeep your talking about is also used as an information center (light bulb status that type of thing) on some models.
part time locks diffs to spin wheels at same speed and just low does not lock diffs and can be driven (slowly) on dry roads when extra torque is needed. (again your model my differ)
I had a dodge ramcharger years ago that had 4 hi 4 hi-loc 4 low 4 low-loc.

"Lo" never highlights on my system, no matter what gear my transfer case is in.

"Part-Time" illuminates when I'm in 4Lo.

If your T-Case is in 4Lo, & your Jeep is stopped, the Jeep should begin moving forward once you let off the brake. That is how I judge if 4Lo is engaged!

Don't drive too fast in 4Lo (just in case you didn't know)!

to my understanding on the 231/242 transfer cases, the 4LO is LOCKED (axles locked together), it is only the 249 (quadra-trac I) that does not have a LO lock, on the NV247 (Quadra-Trac II) there is a 4LO Lock.

NOTE: on the quadra-trac I, it might only be the first couple years of the Quadra-Trac I (NP249) that does not have the LO Lock. I think I remember reading that they did put LO lock on the Quadra-Trac I (NV249), then again it may have been the Quadra-Trac II that I am thinking of.
