The first thing I would Test could be the 4Hi gentle — (maintain it basic) — does the 4Hi mild ever occur on?
numerous folks told me that it had been most deffinetely the encoder motor. so i tried to change it and After i did it place the transfer circumstance into nuetral and the automobile goes nowhere and in addition to the 4wd mistake ligth on my sprint will not head out.
Chris claims: February 12, 2008 at 10:48 pm Thanks to the reply Kyle. Because of the time as well as the temperature outside the house in sunny Buffalo NY, I won’t be seeking nearly anything tonight. I am seeking to do every thing at work on lunch where its heat. To crystal clear up some matters, I've checked the TCCM. I pulled the duvet off and checked the insides and all seems to be very good. Rusty within the out but no indicator of corrosion In the TCCM or maybe the plug. I have visually inspected the EM connector numerous situations. I've tugged around the wires, and it seems to be in great form, no corrosion or apparant damaged wires. Because the past article, I've exchanged the new EM with another new one which a person is exhibiting exact trouble so I am 99.99% confident it isn’t the motor. The previous EM labored when I tapped it Using the mallet, but only for a brief time, fundamentally extensive plenty of to acquire me in 2-hi. Each new EMs have not labored. What is absolutely bothering me is The point that The brand new EM is set up and no blown fuse. Yesterday when I very first set it in, the fuse blew inside of a moment of starting up my truck.
If I’m not mistaken 1999 and back again, the vacuum change is in addition to the transfer situation. 2000 and up it’s over the firewall. If it’s on top of the TC, it seems like a nut with three hoses sprouting from it.
In the event you think about the schematics, you are able to begin to see the motor is simply “controlled” because of the TCCM through sign wires. I suppose it’s feasible that if among the list of motor wires ended up to be shorted it might result in harm to the TCCM — do I feel This is actually the case?
The hyperlinks into the information are eradicated as I did not recognize they were uploaded to your file server to post listed here. I ought to have backed them as many as my server, but did not — I apologize redirected for that.
Examine the schematic “front axel switch & pcm.jpg” — and after that have An additional consider the wires on the TCCM (Transfer Scenario Management Module), Positioned underneath the travellers kick panel.
I didn’t understand I had dropped the links for the schematics likewise over the conversion. What I have, I've included again towards the article at the best from the website page. I hope this can help!
OK, the module location — I'm able to’t actually explain it better than I did for the final remark poster, but in case you missed that part… sit within the passenger seat — swing your right foot backwards and forwards when preserving your heel on the ground — you’ll hit your remaining foot one way, as well as the plastic panel where the module is found another way. Some older pickup trucks had a “vent” pull tackle Situated there, if that assists! As to the chilly producing the problem — might be. That’s the condition — there are numerous items it could be. There may be, what is referred to as an “encoder module”, within the facet on the transfer circumstance that controls which method you're in (two, 4HI, 4LO) — if h2o got in there and froze, it could be avoiding the encoder from switching modes.
The 2nd Inspection is within the engine bay high up on the middle from the firewall. Inspect for vacuum on the change after which you can be certain the hose is’nt damaged producing leaking (Mine was broken off) Excess warmth within the engine compartment will hurt vacuum hoses and excessive curves or bending will lead to problems with hose decay and failure.
It looks like the gears are engaging during the transfer situation but I don’t hear the actuator engaging as well as the lights around the dash don’t appear on. Any recommendations?
If so, and it returns to 2Hi just after you start the motor vehicle, your assumptions are almost certainly accurate. Do you listen to the TCCM simply click in any respect immediately after commencing the motor vehicle?
Not surprisingly, your TCCM can be bad, along with possessing true troubles throughout the ATC by itself. That’s the challenge with programs like this — it can be Virtually everything.
Unplugging the TCCM isn’t a terrific notion as it seriously doesn’t attain anything at all. For anyone who is caught in 4WD (which it feels like you will be), unplugging the TCCM will not likely get you again to 2WD. Nonetheless, I don’t choose to inform you to continue to generate the auto with out being aware of more information — maybe you have a challenge With all the gears/forks in the TC which may not enable the encoder motor to physically change modes — obviously, driving the car or truck On this ailment would only result in better destruction.
