It’s genuinely hard to notify with out having the ability to place my palms on it. Nevertheless, You may additionally want to examine the encoder motor sign strains (C26 via C28 over the pinout from the first publish) — they need to be higher (+5VDC) in the event the are usually not in use (resistors pull the traces substantial), and minimal when they are active (termed “Lively minimal”). All schematics are posted in the main submit of this thread.
The encoder motor may be negative. In any case, if worse comes to worst, you could unscrew the encoder module and manually shift the transfer case into any manner you wish. Sad to say, I can’t inform you which way is which — you’ll should figure that out with demo and mistake! Don’t get worried, you may’t harm nearly anything — you’ll both be in two wheel push, or one of several four wheel ranges. If it’s not two wheel, try out once again until eventually it can be! (There'll be metal “tab”, for deficiency of higher text to explain it, protruding from the transfer case — put a wrench on it and it should shift with negligible exertion. Under no circumstances Pressure Nearly anything! Consider it for any push and find out Everything you’re in. With any luck ,, you’ll get it on the main attempt!
The TCCM is Performing, the encoder motor is Doing work, the front, ideal axle is engaging, along with your vacuum lines are working (you will find far more, but they're the critical kinds). The trick in this article are going to be to see what is 4Hi dependent, and why it won’t kick into 4Hi.
We now have 4WD. My wife is impressed with me and my hat is off to you sir. You saved us huge time. Will gladly fund your retirement account for what you have got saved us. Allow me to understand how.
Sadly, I have not encountered what you're describing and might only present advise for things which I, Individually, have carried out as I'm not a mechanic. I don't know what this pin is, or how much it must transfer.
That’s awesome! Properly, I do think you’ll take the cake — I don’t Believe we’re going to see a mend for any lower than 75 cents! Fantastic function!

The primary problem it is possible to check oneself. Seize the schematics from the primary publish and exam pins 26 as a result of 29 for logic electric power (+5VDC), using pin sixteen as your ground. You might also need to get beneath the auto and test exactly the same wires for the encoder motor. Take a look at the bottom wire there as well.
Make your changes. With regards to the form of steering you may have, There are 2 other ways you can regulate your toe. In case you have rack and pinion steering, you'll want to transform the inner tie rod by itself. Spinning the rod will regulate the toe in or out. When you have a parallelogram linkage system, there'll be modifying sleeves which you could flip to regulate your toe.
As for your encoder motor being fried since the TCCM “got corroded and shorted it out” — yet again, it doesn’t seem more likely to me. You can find (off-the-prime of my head) seven wires amongst the TCCM as well as the encoder motor. two of these are electricity (+/-) and they are FUSE guarded. four of them are signal traces and the final one is signal floor. If the ground wire was corroded and shorted (to what?
com and even acdelco.com . Nobody is listing a module regarding four wheel push or transfer situation. If anyone can help with a supplier of the section, remember to e-mail me at WeinCellar1811@aol.com . Thankyou, Dale
Until you have got working experience doing suspension do the job, you will likely have to choose your vehicle to an experienced mechanic.
