Your problem sounds the same as 10 Other people above you — when you haven’t uncovered The solution in what I have posted To date I, sadly, will not be ready that can assist you and advise having your automobile to a mechanic.
I'm able to in this article the encoder motor activating and deactivating. I wonder If your mechanics did a little something for the transfer case all through rebuilding from the transmission. Anyway, what can be creating this hissing sound in or near this transfer scenario.
I, myself, don’t know of any vacuum Situated with the transfer circumstance, but I'll test to learn for you personally (I've a transmission store while in the relatives — I just termed, though the knowledgable a person is not however in). The TC is very near the front of your motor vehicle — are you positive the vacuum is not coming with the firewall area?
Seems like a entrance diff dilemma. I’m undecided of your decades, though the tranny shop that I experienced mine in the beginning checked for this issue as it is, apparently, popular.
Anyway, skip ahead… all went properly previous weekend, but I nonetheless experienced a broken 4×4 to deal with. And, just as if Murphy hasn’t presently accomplished enough, it’s the vacation time and many sites are only open several odd times. That manufactured issues difficult when I learned what I required to search for!
Should you don’t intellect, I might very much want to publish your responses — if you want, I can depart your identify out — obviously, the selection is yours and I will regard any choice you make, just allow me to know.
PS – the flashing change lights point out the process is trying to communicate with the remainder of the method. When it stops, it means it could not talk to A part of the technique.
No, I don’t have something AFAIK — but I do Use a buddy that has the All-Data method and may have it (he printed out some terrific schematics for my TCCM yesterday) — I’ll question him nowadays and when so I will publish it here in your case.
The primary dilemma you could exam you. Seize the schematics from the very first write-up and exam pins 26 by way of 29 for logic electric power (+5VDC), making use of pin 16 as your floor. You may also wish to get beneath the auto and check a similar wires on the encoder motor. Examination the bottom wire there likewise.
It appears like the gears are partaking while in the transfer situation but I don’t listen to the actuator partaking as well as the lights to the dash don’t appear on. Any suggestions?
As to the encoder motor getting fried because the TCCM “bought corroded and shorted it out” — once again, it doesn’t seem more likely to me. You will find (off-the-major of my head) seven wires between the TCCM along with the encoder motor. 2 of them are power (+/-) and they are FUSE shielded. 4 of them are signal lines and the final one is signal ground. If the bottom wire was corroded and shorted (to what?
Decreased the car. When you reduced the car to the bottom, drive down on the vehicle previously mentioned Every single wheel several periods to allow the automobile to settle.
UPDATED 12/12/07 – I just needed to increase to this article which the TCCM has two relays inside of that Command the particular switching on the encoder motor — you that may be Whatever you hear “clicking” whenever you try out to interact the 4WD technique.
Chris suggests: February nine, 2008 at four:00 pm To start with I really need to say that this blog rocks!! I believe you might be undertaking an great services. I've browse several of these issues but haven't identified one which matches mine exactly. A while back had the traditional encoder motor dilemma where by the truck would go into four-lo or 2-Hello, but would flash and default to 2-hi when 4-Hello switch frustrated. Nicely Check out vacuum actuator less than battery, Tccm, encoder motor plug,etcetera and all was fantastic. Due to the fact my battery was disconnected the DTCs ended up reset and lo and behold my 4WD was Functioning yet again. When 4wd was disengaged I might have a whirring sounds out from the front finish, like 4wd wasn’t completely disengaging the front diff. I might end the auto for a Visit THIS Site few minutes and it appeared to disappear. The other working day, on how to operate the sounds wouldn’t go away, so I attempted putting it out and in of four-Hello a number of situations, until finally it blew the fuse.
