What you describe feels like the ported vacuum change (Notice: this switch is only on 1999 and up cars). I’m not sure to the “Listening to anything managing†— what does it seem like?
so now I've a different transfer situation and in addition to a brand new encoder motor which i cant put on mainly because it will not likely occur away from nuetral on the trasfer case Unless of course i shift it manually. and because i have to depart the encoder off the front axle wont have interaction simply because its not receiving the rigth message.
PS – nope, no other name to the Encoder Motor, that I know of. It’s located over the facet in the transfer case and it what does the Bodily shifting in between “modes†(2Hi, 4Hi/4Lo).
If you discover that it IS your dilemma — a diode in addition to a capacitor must resolve the problem. What you are doing is have a diode (1N4148) and put it on the logic offer line of the TCCM (the polarity marker, a nasty, in the direction of the TCCM), and location a capacitor (100uF 36v need to do it) involving the diode as well as the TCCM. What this does is stops the battery from pulling electricity In the TCCM (by means of the diode) plus the capacitor will make positive you might have enough energy there to “quickly†run the TCCM even though the auto battery is currently being drawn from.
Doesn’t seem good. It sounds like what I just went by — and it turned out to become the gears/forks during the transfer scenario. I to start with recognized which i had difficulty coming out of 4WD, then I started off noticing 4Hi “slipping†out and in.
If I needed to guess — both your encoder motor is shot, or poor wires within the TCCM. If you’re genuinely into it, I’ll post the schematics for your wiring of your method — this will let you trace and exam factors alongside the procedure to pinpoint the issue. (I should scan them, so it may not be today!)
I believed I’d give it a try to see what I could do (the plastic bag the thing is during the 3rd image is made up of a pair additional spare connectors in the event it ever takes place once more… I’ll know proper where They may be!).
Certainly, I can’t assure this is your challenge, especially on the internet, and I hope it isn’t — but I would have it checked out skillfully.
The hyperlinks on the files have already been taken off as I didn't understand they had been uploaded into a file server to publish listed here. I ought to have backed them up to my server, but did not — I apologize for that.
That’s odd that the light will occur on immediately, with out flashing and devoid of partaking the 4WD. The reliable gentle coming on at 4Hi is usually an indication that the program is functional.
Per your aforementioned advice, I've checked the module to determine when there is any seen corrosion but there isnt any. have any thought regarding how to repair this??
Assumed I might Supply you with an update on my 4wd scenario. As I indicated in my authentic post, I had a vaccum line unfastened. I assumed it went to some canister in the fender, what’s a lot more, I believed it experienced a thing to accomplish with my 4wd not Doing the job. Effectively, which was the case. I found the attachment for that line about the canister. I acquired a brand new vaccum line (the a single I had was weathered), put in it and hooked it up to the canister. Then I went into a muddy space inside a sub-division next to mine, drove in to the mud in 2wd. I just sat the spinning the rear wheels. Then I pushed the 4HI button, the light flashed to get a second, then came on good.
It’s not easy to diagnose challenges such as this without the need of with the ability to take a look at things — nevertheless it looks like either the TC encoder motor sign traces are poor (a foul floor could be a difficulty too) or the “forks†in the transfer circumstance are worn, letting the gears to drift, during which scenario the gears for 4Hi is probably not moving into position.
I had been tempted to simply manually sign up for/unjoin the vacuum strains right up until Christmas personal debt is paid out off, but I Click Here come to feel obligated to let them complete the restore given that the pushbutton is in.
