As for the internal workings from the transfer circumstance, I depart that to the pros so I'm able to’t remedy that dilemma either.
Very well, that’s one which I haven’t listened to yet. The “ATS” fuse (that's marked “ATC” on this schematic) supplies 12VDC to 2 substantial orange wires with the TCCM (marked as pins C18 and C19 on the schematic). As I claimed, I haven’t seen this issue prior to, so I haven’t traced that A part of the technique. I can only presume (yeah, I do know!) the since these wires offer 12VDC, They may be accustomed to operate heavier things including the encoder motor (5VDC, and that is the light guage orange wire, is useful for logic — ie. to run the “chips” on the circuit board). Ideally, you are able to see where by I’m heading using this. I’m just trying to think about it logically — In case the fuse is blowing that provides 12VDC, what inside the 4WD process would use 12VDC?
I now feel self-confident to head to my garage with a fair plan of what's Mistaken with my aged still continue to sprightly Merc R170.
In summary, wheel alignment is a crucial purpose that needs to be finished not less than every year. In truth, it might count on the driving habits, street circumstances, and a number of other variables.
Unfortunately we prob designed the mistake of driving it the twelve minutes to your shop as opposed to towing it which might are actually free of charge with out on Star.
I've an ’02 Chev 2500 having a manuel 4X4 shifter. My problem is that 4hi received’t have interaction. 4lo appears to work just fantastic, axle engages, lights around the dash come on, I'm able to listen to entrance axle actuator partaking, but After i attempt Full Report 4hi nothing at all seems to happen.
I’m undecided why you would probably desire to pull the cable over the front diff — I assumed you mentioned the front axle turns when in 4WD but not 2WD? If that's the case, the axle is engaged (indicating the cable is staying pulled).
You might be welcome Ross and thank you for finding the time to go away a remark, I really recognize the suggestions :)
Replacing one particular is a bit high priced because of the labor associated. There are many of elements to get rid of and obtain from the way in which ahead of you can get towards the wheel bearing, Primarily over a four-wheel-drive or front-wheel-push motor vehicle.
Reading through your initially ideas on it, and I’d must say I agree along with you. Does the 4Hi gentle arrive on if you 1st switch the key into the ON position without having seeking to commence the auto?
Not surprisingly, I'm able to’t assurance This really is your difficulty, Specially via the internet, And that i hope it isn’t — but I would've it checked out skillfully.
I would recommend owning it looked at by a tranny shop. The key reason why I recommend This can be, whether it is the problem I explain, the gears are literally rubbing the side of your transfer situation — and they're going to dress in through, properly creating quite a bit more problems than in which you’re at now (ie. full replacement from the TC).

Place a examination lead (volt meter) on the output on the 4Lo button… once you push 4 Lo, does the meter reveal that there's electrical power leaving the button? (It ought to, if what I'm looking at here is right… And that i’m studying it the right way.) Now, do precisely the same for 4Hi (do each tests in park) — does it output similar to 4Lo? Otherwise, you could want to check the harness at the buttons a little bit more meticulously to start with, after which consider applying ability for the output aspect with the 4Hi button (the same amount because the output from 4Lo, regardless of whether it's +12VDC or +5VDC… I’m thinking it should be +12VDC even though).
