my slip abs lights are on and 4wd doesn't work there should be a way to wire 4wd to work. has anyone tried this, or heard of a way to fix it. It would suck to need 4wd and it not work because of a stupid abs sensor.

Well there could be a reason your 4wd doesn't work, hot wiring might only create more destruction. You try a ECU reset??

But if you want to engage the transfer case supply the actuator with 12 volts and stand back.

If you can find a way to wire your transfer case to shift using switches I'd kill to know.
My hangup for putting 4wd on my 2wd is wiring. I'm scared to sink the cash into a transfer case unless 007 ever sells me his lol... and I can't get it to work and cant pass it off to someone else with a 4wd who can use it.
Another member told me it's possible the same member who wrote the how to to run the e-locker in 2hi. I just havn't had the guts to do it yet.
Whitetitanse hats off to that guy who installed everything like it was factory wiring and all what a bear that must've been.

So let me get this straight, you wanna risk screwing up your actuators for your 4 wheel drive, or your electrical system and who knows what else to keep from replacing a $200 part?

My 2 cents, stay out of the mud, save up the cash, fix it right and be done with it

no i wouldn't want to screw my truck up! so you are saying that i would screw it up?
Or is it that you can't think outside the box.
Obviously i don't want to make things worse that doesn't mean they can't work a different way.
I should have bought a chevy but i didn't and now i have to deal with these issues. i want a reliable vehicle that isn't gonna become incapasitated because of a stupid sensor.
i never said i wasn't goning to replace the sensor, and i still don't know for sure that is my only issue or even my issue. I believe i would have to pay the dealer to read codes to tell me if that is the problem.
i don't like the idea that this would keep my 4wd from working, and i believe that there should be a better way.

I think Shane did answer the "hot wire" question... It is a matter of bypassing the so called "safety" sensing of our Titan's elctrical system, like the E-locker mod and Burn-out mod do... Once you find the direct route to power the transfer, you should be able to throw it in 4Hi or evn 4Lo without a problem. Of course, I have no idea where to even start tracking down wires or harnesses to bypass, but I imagine it is very possible. Good luck, and don't forget to do a "How To" thread and share with the rest of us...

If you are going to install another +12V line to the actuator, you may want to look at the wiring diagram and make sure that you are not going to be backfeeding something that doesn't like voltage spikes. This might be avoided by disconnecting the factory harness connections to the transfer case, I dunno. And of course you will probably have some dash lights.

What Cracks me up is the fact that you think a Chevy won't screw you or abandon you over one sensor. Thats funny dude. What year Chevy were you gonna buy, a '77 model? All the new 4x4's have sensors and actuators on every system that controls anything and everything anymore. I would bet my butt that they all would and could strand you over a bad sensor. Some may be more reliable than others i would agree but thats about it. I've had my share of Chevy trucks and their problems as well. My advice would be get the thing fixed right. Any shortcut will come back and bite you one way or another. Good luck whichever route you take.

I am not bull****ting anyone. Yes there are sensor for sensors and even more sensors and they are there to protect the truck and sometimes they can hose the driver, welcome to the modern age.

The actuator is a 12VDC motor. apply current and will move to lock in the T case. Now what I don't know is if the Titan actuator does a back and forth motion or if it rotates. When you will need to know is when to shut off the power once the T case is locked in. I have had to do this on a few trucks at the local mudholes in the past, Fords and Chevy's alike so they will all leave you stranded.

And I would love to see a stock Chevy go sideways out of the dealer parking lot...Normal options truck that is. Vette don't count.

this is some info i was looking for thanks

LOL Chebby's have had their own issues with 4X4 engagement at the hubs so I wouldn't go syaing they are any better.

i don't believe i said there were better and i don't know if the abs sensors went out on a chevy if the 4 wheel drive would still work? but on a titan it doesn't.

i know all vehicles can have problems, and i know sensors on any vehicle can go bad i just think its retarded that an abs sensor would cause the 4wd not to work. Why do they have to be related? It doesn't make any sense to me? I could care less if my abs worked , but my 4wd i do care about.

As far as me perfering to have a chevy, a couple of reasons i can think of easier to fit bigger tires, better gas mileage, better rear axles

now i don't hate my titan i do like it, but

for me to sell my titan and buy a chevy well that would wind up costing me money and effort that i don't want to spend. just because i want something else doesn't mean that i can just go out and get it.

i'm surprised that so many of you object to the idea that there could be a different way for the 4wd to be engaged, and think that abs sensors, working or not should control the engagement of your 4wd.

I was hoping that there was an easy way to bypass the abs or engage the 4wd.

As far as clearing tires you can clear a 33x12.5 on a stock 4x4 Titan that's about as much as your gonna get out of any half ton truck. The newest chevy has good mileage when cruising at or below 60. Anything above 60 mph and when accelerating it's not getting any better mileage than a Titan. Better axles yea probably. And as far as the abs sensor controlling 4x4 I'm pretty sure it doesn't allow it to engage as a failsafe to keep you from causing damage somehow, otherwise there would be no reason for the two to be connected. The abs sensors are not that big of a deal I've had to replace 3 all at once, but that was because of a bad jumpstart that burnt them up. I'm sure there are some that have just failed for no reason, but most I've heard of were damaged when installing lifts and what not
 
#25 ·
It was a battery charger with a jumpstart setting that I have used several times on different vehicles before and after using on the t with no other problems, but when we hooked it up to the Titan something went wrong the interior lights got really bright and started buzzing, and then lights started popping up on the dash. It blew 3 abs sensors and 4 or 5 lightbulbs

yes you can bypass all that crap. the 12v dc actuator answer is correct. get 2 3pole switches, a hot to engage, neutral once it is engaged, then to release it. you will need 2 switches or 3. 1-4hi, 1-4lo, 1-2hi. you can do this with ANY electronic transfer case.

someone was talking about making their "t" a 4wd, best bet is to buy the atlas transfer case, cut you cent floor board out, mount it up. cutting the floor board is for the levers for the t-case.

I have a center console though was my only issue and I can get an oem t-case cheaper.

I did look hard at the atlass II and the remote levers with like 6" cable but where to put them and retain the floor shifter is a doozie.
I made this billet panel to fit in the console cubby area and wanted to mount my switches there if I cold get some help wiring. I have a friend who is a guru with electrical his thoughts were he probably could but he'd need to see the t-case then go after it with his meter.

it sits flush I just left it popped up so I could get it back out since theres no holes drilled for switches or anything. I also considered some guages but If wiring would work 4wd is on my horizon.
 
#29 · (Edited)
bout how far is the throw on the levers? Or would I have to turn them sideways? I pictured that in my head but it seemed funky lol two levers poking up sideways. maybe I will keep the billet peice as a cover or mount some actuators to the atlas and use pnuematics to shift it lol

hey sahara ever considered an atlas II?
 
#31 ·
the throw isnt very long at all. it would fit upright in that console.

I want to make a suggestion here , go buy the CD on ebay for your truck , It has all the information on the whole titan with all the scamatics for the complete trans from 4 wheel drive to complete engine and everything else when it comes to wire with all wireing diagrams , it is great , and whenever I have a problem I goto it and it is very easy to use , or if you want a copy of mine I will send it to your for $6 shipped , this is the best thing for any vechile ,one more thing I notice that their alot of people who do not even know what is going on is ready to say some neg comment because the think they know what they are talking about , this and all forumn sites are there to help with support or sugestions not to judge and be negitive with therir remarks ,

I wish there was, my abs sensors have gone out 3 different times.

So let me get this straight, you wanna risk screwing up your actuators for your 4 wheel drive, or your electrical system and who knows what else to keep from replacing a $200 part?

My 2 cents, stay out of the mud, save up the cash, fix it right and be done with it
sometimes you have to go in the mud for something, its what some of us bought 4x4s for, not just playing. its a real big disability having a 4x4 that just dont work.

no i wouldn't want to screw my truck up! so you are saying that i would screw it up?
Or is it that you can't think outside the box.
Obviously i don't want to make things worse that doesn't mean they can't work a different way.
I should have bought a chevy but i didn't and now i have to deal with these issues. i want a reliable vehicle that isn't gonna become incapasitated because of a stupid sensor.

i don't like the idea that this would keep my 4wd from working, and i believe that there should be a better way.
go to tire and brake shops they do the read for like 35 bucks.
