Jim claims: February 25, 2008 at four:07 am Maybe you may also help me. Today I left for get the job done and my truck was in 2HI. About 5 minutes in the future no lights had been on, in my 4×4 activate the dash. I pushed the 2HI button and it lit correct up. My truck does go into 4LO as I can hear and really feel it partaking. My truck also appears to go in and out of 4HI and 2HI.I discovered a ice place on the pavement and when its in 2HI it will spin , but when I hit 4HI I listen to a slight clunk and it'll acquire off like its in 4HI.
so now i have a fresh transfer situation and along with a fresh encoder motor that i cant put on since it will not likely come outside of nuetral to the trasfer case Except i change it manually. and because I've to go away the encoder from the front axle wont have interaction for the reason that its not getting the rigth concept.
Man, if it’s simply a button assembly, don’t be concerned — there isn't any electronics in the button assembly — They're just that — buttons (switches). Meaning, it shouldn’t cost everything Substantially. The costliest section will be the dealers labour amount.
My two wheel drive would have interaction but not my four. I examine the tccm as well as vaccum change and to my certain amazement the vaccum line experienced damaged off the change. I mounted this problem and now my 4 wheel travel is Performing yet again. The data you posted saved me a visit to some vendor!!!
As with the vacuum swap you linked to earlier mentioned — could incredibly very well be the condition. For $eighteen.ninety five, it’s cheap to understand! Nonetheless, for pennies you can test it — NAPA (and probably Other folks, like PepBoys, etc.) will have vacuum hose connectors — male to male connectors will assist you to stick 2 vacuum traces collectively.
The other wire I might Check out will be the A/T (Computerized Transmission) change lock switch — This is often wire #31 and is also light-weight inexperienced that has a black stripe (you will find much more web pages from the schematics over… the first is a hand -penned webpage of your TCCM connector pinout). This wire ought to have voltage placed on it at certain situations — regretably, I haven't had to diagnose that Element of the system, so I don’t know if it should be +5VDC or +12VDC (but It'll be one of these!
sure enough the vacume line was terrible by the valve protect. I very first transformed the vacume activate the transfer scenario but it was only $16 And that i by no means have to bother with it all over again. So for $26, and the broad information on this site, I invested about two hours to have it Doing the job. Can’t thank you adequate.
They ended up deciding my vacuum switch was shot and After i went again The brand new swap even now didn’t do the trick, so that they determine it needs to be the particular pushbutton assembly over the dash. ugh. No clue what that’s gonna cost, but I wager it’s spendy. On the bright facet they confirmed me where the switch was and how to manually enable/disable 4wd by splicing the vacuum lines along with a snippet of brake line Performs like a attraction in hi and lo now to ensure that seemingly procedures out the rest of the system.
I used to be pretty pleased whenever they held, that’s for sure! I mounted the module again around the body, reinstalled the kick panel and my four×4 wheel alignment near 90723 was back in business.
Oh, the click you hear is, most-likely, the relays in the TCCM seeking to change into 4Lo. In case you come to a quit As you listen to that, you’ll in all probability change into 4Lo (your velocity has to be less than 3MPH or 5KM/H to change into 4Lo which is why it retains clicking while you push — it attempts to change for 30 seconds, then gives up).
The vacuum switch shouldn’t make A great deal noise, not enough to become baffled with anything running. What I think is you will be hearing the encoder motor on the transfer situation attempting to shift it into 4wd.
I wouldn’t endorse driving it for long periods, especially on dry pavement if it IS in 4WD nevertheless — it is incredibly really hard to the drivetrain / 4WD technique.
It doesn’t sound like it’s the same kind of procedure, so I’m not really certain what to advocate to you. My process is usually a purely electronic a person (where you push a button, which activates a motor to change modes for yourself)… yours looks like a mechanical process where you engage the 4WD manually (flooring shifter) and the light comes on just as an indicator.
Now, I don’t know if I hurry suitable out for the seller as there could be a handful of compact problems that will induce this problem, according to what that individual model/yr has long been programmed to detect.
