How to tell In case the TCCM is lousy? Properly, that’s a bit far too involved for me to element listed here (essentially, it consists of systematic testing of the assorted wires). If you're able to study a schematic, Then you certainly’ll know what to do with it — all schematics which you’ll want are in post 1 of this thread.
When you are absolutely sure the signal with the button is achieving the TCCM, then either the TCCM is undesirable, or perhaps the encoder sign traces have already been broken. All over again, I’d need to exam wires being optimistic, nonetheless it seems (with the schematics) that the encoder signal lines are incredibly hot (pull-up resistors are increasingly being demonstrated on Every single signal line) and therefore are pulled minimal to activate a particular mode. Pins 26 as a result of 28, on the TCCM pinout, would be the encoder sign traces.
Commonly, that is telling you that there is a difficulty while in the transfer circumstance — problems codes needs to be set, so have your vehicle scanned by your mechanic. I haven't any knowledge Together with the 4WD support light-weight, so besides that, I have no more details.
That’s some very good data to obtain. Be sure to do allow me to know the way you make out Together with the encoder motor replacement.
They ended up choosing my vacuum switch was shot and After i went back again the new switch continue to didn’t do the trick, so they figure it have to be the actual pushbutton assembly about the sprint. ugh. No idea what that’s gonna Price tag, but I bet it’s spendy. On the intense side they showed me the place the switch was and how to manually allow/disable 4wd by splicing the vacuum traces along with a snippet of brake line Will work like a allure in hi and lo now in order that seemingly principles out the remainder of the system.
GM incorporates a style and design flaw Within this particular transfer case — the “forks” experienced plastic bushing that will use out and permit the gears of the TC float, and will not likely pull the gears into their good positions.
As for the vacuum switch you associated with earlier mentioned — could very very well be the problem. For $18.ninety five, it’s affordable to see! Nonetheless, for pennies you'll be able to examination it — NAPA (and possibly Other individuals, like PepBoys, etc.) could have vacuum hose connectors — male to male connectors will assist you to adhere two vacuum lines collectively.
No, I don’t have everything AFAIK — but I do Have a very buddy which has the All-Info program and can have it (he printed out some fantastic schematics for my TCCM yesterday) — I’ll request him currently and if so I will article it in this article for yourself.

Find your tie rod ends. The tie rods are definitely the relationship in between your steering system plus your wheels. The rod finishes are L-formed sections sometimes identified near The within in the wheel.
The examining around the micrometer suggests the camber angle from the wheel. The micrometer mechanism pivot is spaced such that 2mm of micrometer journey equals a person diploma (when kept near perpendicular). This gauge has an angle resolution of 1 thousandth of the diploma, nonetheless it's precision is most likely much more inside the community of 1 hundredth of the degree. The fixture can accommodate rims from twelve" to about 19". An image of It is maiden voyage is demonstrated below.
I’ve intended to think about the heating system considering the fact that like final winter — just never appear to get all over to it (probably ’induce I don’t utilize it in the summertime… After i sense like fixing it!
