That’s a fantastic story! Thanks for sharing that with me… that is all I want! I’m not requesting nearly anything, but Listening to stuff such as this makes me experience superior. Fantastic which i was in the position to assist another person out… and conserve you some cash in the process.
Additionally you want to examine the wires at the encoder motor as These are subjected to the elements and *could* be harmed by something flying up below your auto (unlikely, but feasible).
Now, if you DO hear the “click on-click onâ€, then your TCCM is Doing the job and endeavoring to change into 4WD — the problem, IMO, would then be Using the module that is actually on the transfer situation (I overlook the expression for it at this time) — it is a straightforward “motor†setup that basically moves the transfer scenario gears to the appropriate manner.
I'd the front diff rplaced along with the cv axles checked for injury nonetheless it nevertheless does it. Pondering if you might assist me out? Thanks
The vacuum for that 4WD procedure commences to the drivers side, goes towards the vacuum actuator in the course of the firewall (but below the distributor and hard to see — This really is what I believe you hear — there is a picture up about 10 posts or so) then goes for the diaphram beneath the battery.
One thing you could Verify rapidly is to lay down beside the automobile and possess someone Bit by bit generate ahead (though in 4WD)… you’re aiming to see In case the driveshaft within the TC for the front diff is in fact turning. Whether it is, the challenge is forward of that (ie. front diff), Otherwise, the condition is while in the TC.
) it wouldn't trigger the encoder to fry. If any from the sign traces are shorted, yet again, it would not lead to the encoder to fry since the signal strains are pulled large which has a “pullup resistor†— and so are Meant to short out to floor to drag the road reduced. At worst, Should the sign strains ended up shorting out, you’d go into the wrong mode, or none in the least — but it will fry the encoder — I’d be prepared to certainly be a months paycheck on that.
Replaced the fuse and quickly blew once more, I used to be trapped in four-hi. Came household that evening, tapped within the transfer case and encoder motor using a rubber mallet, changed the fuse and 4wd labored. Set truck in 2-hi and no noise. Started the truck yesterday as well as fuse was blown all over again. Eventually went and acquired an encoder motor and replaced it this early morning. Now almost nothing seems to operate but TCCM(which seemed to get the job done fantastic prior to). Press 4-Hello button, and TCCM clicks about five periods, then defaults back to two-Hello. Exact same detail in four-lo. Following seeking this about five situations, it gained’t even attempt to go in 4wd, just clicks and stays in 2-hi. Pull battery and it resets but goes back to exactly the same difficulty. Remeoved the Encoder motor and reinstalled, no luck. Any Suggestions?? Do you believe I got a foul encoder motor from sections retailer? I don’ty have ample hair as it really is, I don’t want to pull extra out. Thanks.
In addition to that, it’s doable that you choose to received a bum encoder in the components retail outlet, but how web link very likely could it be genuinely? Try what I have claimed above and publish back right here if matters continue to aren’t Doing the job as they should and we’ll see what else we can easily visualize then.
She couldn’t get it to work thereafter. I found that four-Lo labored when in neutral, but when I picked 4-Hi I’d hear the relay simply click during the TCCM, the LED to the swap would flash on, but then it might check out 2WD.
Now we have checked fuses,(all Okay) the TCCM experienced slightly corrosion but all indications are that it's working. 1 vacuum line was broken and we repaired it. We're not confident with regard to the vacuum change working properly or not. I'm able to’t go into a mechanic for numerous days. What we want to know is: Can we unplug the TCCM and push the vehicle safely and securely right until I could get it to your mechanic? Thanks for your personal enable
Same factor as Pablo higher than. Your web site helped me a lot I cant thank you sufficient. Just a little suggestion, I couldn’t discover any terminals in the electronics retailers that might in good shape this connector, so I rigged some Laptop terminal wires and they in shape just great, no glue desired either. You saved me a “bunch of cash†and I didn’t even have to switch to Geico.
If that's so, and it returns to 2Hi just after you start the car or truck, your assumptions are most likely accurate. Do you hear the TCCM click at all right after starting the car?
Greg suggests: December 19, 2007 at one:22 pm Many thanks for the additional ideas. I wound up just having it in towards the shop simply because I was in about my head after I obtained further than seeing the shaft turning and the necessity was urgent (truck doesn’t travel worth a darn in ANY volume of snow w/o 4wd).
