First, I apologize with the hold off in responding — I had a nuts handful of months around the vacations and didn’t do A lot blogging.
Like I said, I'll attempt to make sure to get some extra pics — ideally this can help you uncover your module however! Regards;
the Orange plug wont Unplug. and all People minimal wires They are really speculated to linked ideal?.. i actually see one particular wire wholly from the leading plug. cant see where it belongs tho simply because i cant get the plug off. Idk any assist might be fantastic.. and people photographs you explained you ended up gonna choose would be brilliant.. Many thanks.. Jay
The TCCM is Performing, the encoder motor is Doing the job, the front, correct axle is partaking, and your vacuum strains are Functioning (you'll find additional, but these are the essential kinds). The trick listed here is going to be to understand what is 4Hi dependent, and why it gained’t kick into 4Hi.
Doesn’t audio fantastic. It seems like what I just went through — and it turned out to become the gears/forks inside the transfer scenario. I initially recognized which i experienced difficulty popping out of 4WD, then I started off noticing 4Hi “slipping†out and in.
Set that and nonetheless no 2hi. Once i try to change from 4hi to 2hi I can hear the encoder motor & vacuum solenoid about the firewall do their job and likewise the Manage module clicking so I presume it’s doing it’s job. I've two lights on sprint resulting in get worried, ‘Services 4wd’ & ‘ABS’. Would the abs system fault avoid it from going into 2hi? I understand your not a mechanic but have you any data for me?
OUCH! That hurts. Yeah, this is really The rationale which i set this facts up in the first place. I'd a absurd quote initially, they usually (the dealership) hadn’t even checked out it — they ended up just going to begin replacing elements.
I submit what I have encountered in the course of My very own REPAIRS — I put up this facts and point out that, but somehow men and women under no circumstances examine the posts, nonetheless they go away comments or remarks asking me how to fix something that I'm sure very little about.
I hope this data can help any individual with an identical difficulty. Also i have breakdowns of almost everything on these motor vehicles Be at liberty to e mail me for something else I really like your sight and believe that data like this should be shared to any one.
That’s odd that the light will occur on promptly, devoid of flashing and with no partaking the 4WD. The stable light coming on at 4Hi is often an indication the system is functional.
For anyone who is referring towards the TCCM (Transfer Case Regulate Module) — Certainly, it really should click on with Every single alter as a result of mechanical relays made use of in the module to perform the particular switching.
Place a test guide (volt meter) about the output of your 4Lo button… once you push 4 Lo, does the meter show that there is electricity leaving the button? (It should, if what I'm examining Here's right… And that i’m studying it correctly.) Now, do the identical for 4Hi (do both equally tests in park) — does it output the same as 4Lo? If not, you could desire to examine the harness at the buttons a little more diligently very first, and after that test implementing electricity to the output side from the 4Hi button (the same level since the output from 4Lo, no matter if it's +12VDC or +5VDC… I’m pondering it should be +12VDC while).
Jodie Perry suggests: November thirty, 2014 at 9:21 pm Focusing on a 2000 Blazer and obtaining precisely the same issue as many are While using the 4 wheel travel not partaking. I appeared on the internet and discovered that the commonest issue could be the transfer case vacuum switch. Following lots of hours crawling beneath the Blazer and watching numerous films over the location, I gave up and jumped again online to determine what I had skipped. Seemingly, I discovered, that In case you have the 4 button four wheel push selector, you don’t Use a vacuum switch on the transfer case…..you have got the TCCM, an actuator plus a vacuum actuator switch. I checked out the actuator to start with of the process as well as the cable was absolutely free and crystal clear. Went forward and lubed it up permanently evaluate too.
Another point I found was that you choose to claimed the lights around the sprint will You Can Check HERE flash any time you press 4Hi — this lets you know the button for 4Hi is Performing, as well as TCCM is accepting the sign from it. So, it boils right down to a problem somewhere between the TCCM and also the encoder motor — I'd suspect the TCCM — quite possibly wiring, or quite possibly a bad TCCM.
