Rudy suggests: March 24, 2008 at three:38 pm I'm possessing an issue with my 4WD not likely into 4HI, I push the button and almost nothing occurs. I set the truck in neutral and hit 4LO it goes in, then I push 2HI and it goes back again. Once i have it in neutral and press 4HI each 4HI and 4LO lights flash and after that goes back to 2HI. I read through that when you jumper pin 13 on the information backlink cable to floor, then change important into the ON place the lights on the 4WD buttons flash a code, so I attempted it and sure sufficient a code of 2 flashed meaning motor/encoder failure.
Here are some far more visuals on the TCCM. They aren't mine, but I honestly can’t remember who sent them to me presently (I just located them even though cleaning up the backend of the site and didn’t know they were there.). Should they be yours, allow me to know and I’ll article Picture credits. Thanks!
The TCCM is Functioning, the encoder motor is working, the front, suitable axle is engaging, and also your vacuum strains are Functioning (there are actually more, but these are definitely the essential ones). The trick in this article are going to be to discover what is 4Hi dependent, and why it gained’t kick into 4Hi.
You must do some more investigation to deliver more info — there’s a myriad of points to try posted higher than.
Secondly, your sprint buttons will pop out in the dash with little work — pop out the module and check the wiring harness around the back again of that. I’ve read of individuals encounter issues with the actual buttons.
Sadly, I can’t offer you a definitive response towards your trouble, but if I'd to state, I’d glance elsewhere, other than your TCCM (encoder or transfer case)… but then again, I’m not a mechanic either… so I'm just guessing!
It could be brings about the motor, or perhaps the motor itself — it’s not easy to say with out being able to test items. At best, it’s a corroded wire for the motor — Enable’s hope for that.
I’m not one hundred% on the 1995 product year, if the controls are in sprint or what (I'm sure They can be on 98-05). My in dash Handle has two, 4HI then 4LO, Each and every with their unique light to point which manner is engaged. If you have interaction four LO, if You aren't in neutral (or reverse, but underneath 5MPH), the 4HI and 4LO lights need to flash then 4HI will kick in in lieu of 4LO — This is often what I feel can be happening to you and why four Check Out HERE wheel generate is kicking in at 25MPH (4HI will kick in at Considerably higher speeds than 4LO). This might point out a module wiring challenge, it’s difficult to actually say, but a very good place to seem.
Still it shows in “four wheel very low†I experience my future transfer is eliminating the front push shaft , and pulling the servo change motor on the transmission , it appears to be as If your are around nine wires about to that servo motor, I’m I on the right tranck ?
You aren’t getting any flashing on the lights in any respect (if you consider to interact 4WD)? There must only be 1 mild on at a time (indicating which range that you are in) — many lights should flash after you test to have interaction 4WD (possibly Hello or Lo). If you are trying to have interaction 4WD as well as lights do not improve (ie. no flashing), I might suspect a problem with both the wiring to the TCCM or even the TCCM alone is poor.
I can right here the encoder motor activating and deactivating. I'm wondering If your mechanics did a thing to your transfer scenario for the duration of rebuilding of your transmission. In any case, what can be creating this hissing audio in or near this transfer case.
What you describe looks like the ported vacuum switch (NOTE: this change is only on 1999 and up motor vehicles). I’m undecided about the “Listening to some thing managing†— what does it audio like?
Ryan says: April two, 2008 at nine:24 pm Thanks for that response to my submit earlier, And that i had pep boys do a vacuum take a look at to the technique and so they stated each individual detail was appeared to be ok, so I purchased that four wheel drive swith from napa and set up it,(it went into the front axle suitable where the cable in the actuator attaches), however no luck. so i could see some type of sensor in addition to the transfer scenario with three vacuum lines connected to it, so i replaced i, and Yet again nonetheless very little, so i have a couple extra inquiries…their is yet another sensor around the tail pice of your transfer case, i was advised it's the speed Handle sensor, could that be the trouble?
The only issue you will have is because you have two wires disconnected, you will have to know which 1 goes to which hole (terminal). In the event you tell me the colors, I am able to try to Identify them for you personally (be particular with wire colors — ie. white with light inexperienced stripe, pink with dark blue stripe, etc.).
