Ryan states: April 2, 2008 at nine:24 pm Many thanks for that reaction to my post before, And that i experienced pep boys do a vacuum check about the process and they claimed every single thing was appeared to be Okay, so I purchased that 4 wheel travel swith from napa and put in it,(it went in the entrance axle appropriate the place the cable from the actuator attaches), continue to no luck. so i could see some form of sensor on top of the transfer scenario with 3 vacuum lines connected to it, so i replaced i, and Again even now very little, so I've a pair much more queries…their is an additional sensor to the tail pice with the transfer case, I had been told it is the velocity Handle sensor, could that be the situation?
Considering that October is primary fishing time on NC Outer Banking companies and 4wd is essential, can I manually place auto in 4 hi by pulling the cable that goes into actuator? for A short lived correct. Back diff seems to lock but is difficult to inform all-around right here, as well flat and also dry.
The encoder motor is the first thing that relates to brain. Yet again, I have not attempted this, however, if it were being me, I'd attempt to disconnect the encoder motor and take a look at yet again (this might not get the job done given that the technique may detect the unplugged encoder rather than consider to engage 4WD — the dash lights need to flash if it’s seeking to engage 4WD). In the event you don’t blow a fuse Using the encoder motor changed, you have found your difficulty — nicely, sort of. From there it could both be the motor alone, a Bodily obstruction on the motor (the shaft may very well be frozen (corrosion) into the transfer case stopping the motor from going) or wiring in between the encoder motor as well as the TCCM (a short from offer to ground).
Raymond Dunne states: January 7, 2008 at ten:27 am Properly just after alot of time on my 2001 Jimmy 4wd process I'm even now stumped. Started which has a clicking noise from front finish so I checked vacuum actuator and it’s executing it position since I loosened up the cable. Truck will not go into 2hi or 4lo so I pulled the control module and checked wiring. Big orange wire on energy connector was covered in corrosion and a single wire on 32 pin connector was corroded.
I've change the sprint selector, checked out the tccm module it clicks but will not likely appear outside of lo four wheel travel, I disconnected the vaccume module in the center of the fire wall.
It’s difficult to say what your issue is. I’d get started with thinking about the encoder motor — If you're able to listen to it run briefly, then what I might do is take it off the transfer circumstance and try to engage 4WD then — enjoy the motor and find out what it does — try it in all modes (2Hi, 4Hi, 4Lo) and check out the motor. If that appears to be Alright, another issue I'd do is usually to attempt to manually change the TC with the “tab” that should now be sticking out from the aspect in the TC (under the encoder motor that you just eradicated) — it is this tab the encoder motor turns to have interaction the different modes.
Test your tire tension. Your tires need to be appropriately and evenly inflated before you progress. Tires that are not effectively inflated might truly be the cause of your functionality troubles, so It is a smart idea to Verify this primary. You may not should do anything else.
If I'm not mistaken, You can't distinct codes yourself — you must have someone do it that has a scanner (ie. SnapOn). I might be Mistaken, but I don’t Feel so — I have a tranny store in the loved ones which has one particular, so I’ve hardly ever had the necessity to research it any further more.
If you don't listen to the “click on-simply click”, you've got a bad relay during the TCCM. The excellent news — you will get a substitution relay at your neighborhood electronics keep and change it from the TCCM. You will require a soldering iron and many essential electronics abilities, but it is rather simply realized (two or three details to unsolder after which resolder the new relay set up).
When it stopped Doing the job, I went hunting… initial powering the glove box, but I could clearly see visit their website that the one relay (the things which make that “click on – click on” seem) there was for that signals (turning about the hazard lights verified this when you will be able to Plainly hear the relay, as well as really feel the click if you put your hand on it).

If by unplugging the TCCM you hope to which the car will default to 2WD — it won’t. So long as it’s actually working and driving your axle(s), depart or not it's and have it into a mechanic ASAP.
Upon conversing to some yards, they apparently acquire these modules out ($$$$$$$) and simply cut the connector off and sell it With all the module. So, that actually only leaves me into a scrap yard that allows you to walk all over… and haven’t eradicated the module… don’t wanna go there.
Wheel sensors haven't any role in a very wheel alignment. The sensors are there to simply count the amount (and price of velocity) of rotations of your respective wheel while you drive. Many thanks! Certainly No Not Handy 0 Beneficial 3
