The first thing I'd personally Check out may be the 4Hi light — (continue to keep it uncomplicated) — does the 4Hi mild at any time appear on?
In case you are positive that the sign through the button is reaching the TCCM, then possibly the TCCM is lousy, or maybe the encoder signal traces have been weakened. All over again, I’d need to take a look at wires to be positive, but it seems (through the schematics) that the encoder signal traces are very hot (pull-up resistors are increasingly being revealed on Every sign line) and so are pulled very low to activate a specific method. Pins 26 through 28, about the TCCM pinout, would be the encoder sign strains.
Sorry, can’t assist you with that one particular — the Silverado I don’t know. It looks like you might have AutoTrack while. As I claimed to a preceding poster, I don’t know A great deal in any way about AutoTrack, aside from it’s a “set and ignore” style technique.
You’ll figure out shortly adequate out of your mechanic. Meanwhile, there’s two web pages of Q&A previously mentioned you could read.
Do the identical on another aspect. If there isn't any spot on the tire where the tread is flat, you may have to suspend your marking Software which has a clamp or identical stabilizer.
If you select to start a new Discussion board topic, you may connect information for your article. If you decide on to upload an image, it is going to produce a new subject matter within just my blog site (which I'll then shift to get provided within your original publish).
I, myself, don’t know of any vacuum Positioned within the transfer case, but I will try to determine for you (I have a transmission shop inside the relatives — I just identified as, even so the knowledgable a person isn't nonetheless in). The TC is quite near the front with the vehicle — are you currently positive the vacuum is not really coming from the firewall region?
Wheel sensors have no job in a very wheel alignment. The sensors are there to easily depend the variety (and price of speed) of rotations of your respective wheel as you generate. Many thanks! Indeed No Not Practical 0 Beneficial 3
I previously changed the balljoint and the tie rods, but my Discover More Here front passenger wheel remains off. What else am i able to do to repair the alignment.
Doesn’t sound very good. It looks like what I just went by — and it turned out to get the gears/forks while in the transfer circumstance. I initially discovered that I experienced problems coming out of 4WD, then I begun noticing 4Hi “slipping” in and out.

If you find that it IS your problem — a diode and a capacitor should really take care of the condition. That which you do is obtain a diode (1N4148) and spot it around the logic offer line on the TCCM (the polarity marker, a foul, toward the TCCM), and location a capacitor (100uF 36v really should do it) involving the diode as well as the TCCM. What this does is stops the battery from pulling electricity From your TCCM (via the diode) plus the capacitor makes confident you might have more than enough ability there to “temporarily” run the TCCM even though the car battery is staying drawn from.
Now the place the heck that point is…I have not received that much. Hope this aids all of us broaden our expertise on these good high maintance vehicles!
three) the encoder motor/module is negative. This is actually the module/motor that may be mounted straight to the transfer circumstance, who’s occupation it is actually to bodily transfer the gears of the transfer situation To place the TC into the assorted modes (2Hi, 4Hi, 4Lo).
