You will have to provide me some more info — like what, precisely, ended up you executing any time you obtained the company light to head out? Exactly what is the process undertaking now, if just about anything? Have you checked Your fuses (even those under the hood?). Did you look for corrosion on at the TCCM?
You realize, it sounds an awefull great deal like what mine was performing — which turned out to generally be the “plastic” bushings between the forks In the transfer circumstance.
Greg claims: November 27, 2007 at twelve:fifty one am Thanks for The good tips. I used to be equipped to figure out a number of your additional simple tips and confirm that my front travel shaft is popping even though in 4wd but not in 2wd. Thus far so very good (It appears to me), so I’m investigating utilizing my newfound knowledge re.
The one thing I can propose, which may be of no price for you, will be to attempt to swap out the TCCM. You could possibly check out a applied one particular through the scrap yard, but you in no way definitely determine what you’re acquiring there (you could be in worse condition). You will find firms that rebuild them (the final one I read my buddy for the garage get was like $150, his Price tag, for just a rebuilt unit), or, ideally, your mechanic can have an excellent a single all over that you can use to check out if which is the situation (naturally, with the latter system, you will have to have an awesome connection with all your mechanic!
As for the rest of your difficulty with the TC becoming in neutral — I don’t know The solution to the query — so far as I am aware, 2WD is neutral so far as the TC is concerned.
The only real other thing which i can counsel is really a “home maintenance”. Clearly, I don't know what kind of difficulty you're obtaining, but Permit’s presume that you've got sprint lights and The sunshine DOES go to the 4×four superior (or low) position — at this point, hear see whether you listen to a definitive “click-click on” coming in the TCCM.
PS – I have modified the configurations to permit registered associates to add pictures/documents. If you want to upload, you must sign-up. Sorry, however the spam along with other crap is simply ridiculous any longer.
In case you listen to the click from the TCCM, that lets you know which the relays are working and are trying To place the encoder motor in gear. There are various motives for this to happen, broken/leaking vacuum strains to start out. The encoder motor wires could possibly be bad. You will find a “plastic bushing” that keeps a “fork” inside the transfer circumstance while in the placement (nicely, the fork keeps the gears in the right posture)… In case the plastic bushing is worn, it can cause the transfer scenario to not change (this happened to me, but the indicators had been which the procedure would swap to 4Hi/4Lo, having a big clunk, and it was quite challenging to have it back again from 4WD.)
Greg claims: December 19, 2007 at 1:22 pm Many thanks for the extra tips. I wound up just taking it in to the shop because I had been in above my head once I bought over and above viewing the shaft turning and the need was urgent (truck doesn’t push worth a darn in ANY degree of snow w/o 4wd).
You already know, besides what I’ve posted over in regards to the forks/gears, I don’t actually know Considerably about them — I had the challenge stated to me although I used to be driving house on the freeway in rush hour targeted visitors. I never really questioned any issues even further than that — ’cause my 4WD worked!
Rudy suggests: March 24, 2008 at 3:38 pm I am owning a problem with my 4WD not going into 4HI, I press the button and absolutely nothing transpires. I put the truck in neutral and strike 4LO it goes in, then I push 2HI and it goes back again. When I have it in neutral Hop Over To This Website and press 4HI each 4HI and 4LO lights flash and after that goes again to 2HI. I examine that should you jumper pin thirteen on the data url cable to ground, then switch crucial on the ON placement the lights to the 4WD buttons flash a code, so I attempted it and confident ample a code of two flashed indicating motor/encoder failure.
There's a schematic (on site one) from the front axle swap — it appears to become tied to ground by way of a “pull-down” resistor. When engaged, it should be pulled higher (+5VDC or +12VDC, I don’t determine what it’s applying to the switch).
Hello Les — I’m planning to really have to say no as Raymond now not has them — yet again, I apologize for not backing them up.
