If you are confident that the sign from your button is reaching the TCCM, then either the TCCM is poor, or maybe the encoder signal traces have already been broken. Yet again, I’d should test wires to be favourable, but it seems (from your schematics) the encoder signal traces are hot (pull-up resistors are being shown on Each and every sign line) and are pulled reduced to activate a specific method. Pins 26 through 28, over the TCCM pinout, are the encoder signal traces.
Many thanks for that update — that’s what we love to listen to! I’m happy to have already been capable of aid retain a number of of those greenbacks inside your wallet — In particular at Xmas! Best Regards;
I possibly saved hundreds if I might have gone to the dealer. I would have completed the work myself, but I do not have a elevate Which small component was a soreness to obtain, or simply get it out for instance.
Rudy states: March 24, 2008 at 3:38 pm I am possessing a difficulty with my 4WD not heading into 4HI, I press the button and absolutely nothing transpires. I place the truck in neutral and hit 4LO it goes in, then I push 2HI and it goes back again. After i have it in neutral and press 4HI each 4HI and 4LO lights flash and after that goes back to 2HI. I examine that in case you jumper pin 13 on the data backlink cable to floor, then convert essential for the ON position the lights to the 4WD buttons flash a code, so I tried it and absolutely sure plenty of a code of 2 flashed meaning motor/encoder failure.
The main dilemma you could test on your own. Get the schematics from the very first write-up and exam pins 26 as a result of 29 for logic power (+5VDC), utilizing pin 16 as your ground. You may additionally choose to get underneath the car or truck and test exactly the same wires on the encoder motor. Check the ground wire there at the same time.
I actually don’t contain the knowledge to convey definitively Sure, or no — but I want you the best of luck. Make sure you, let's know how you make out.
“Reducing the elevate into the locks is not only a security precaution, In addition, it helps shield the elevate from untimely dress in. Store managers should really share this short online video with their personnel to generate residence the importance of usually reducing lifts for their locks.â€
1st, remember to Take note that I am NOT a licensed mechanic! I like car do the job and do a lot of my own do the job, and so acquire the expertise that I share within just my weblog. OK, so enough with the disclaimers by now!
Now, I don’t know if I rush ideal out on the vendor as there generally is a couple of modest issues that would trigger this situation, based on what that individual design/yr continues to be programmed to detect.

When the transmission engages, however the front hub does not, you do have a vacuum issue. Now, this does not always mean There exists a problem Together with the physical vacuum lines, or vacuum itself — it *could* mean the vacuum swap is just not receiving ability, which might not allow for it to turn on, which might make the influence of no vacuum with the diaphram and, very well, When you've got no vacuum with the diaphram, your front, appropriate axle will no engage.
PS – the “encoder motor†will be the part that “holds†your TC in the varied modes (very well, that’s not 100% exact possibly — the encoder motor shifts from a single manner to the other — sections In the TC actually “maintain†you in that manner — in my situation, it absolutely was a list of “forks†with plastic bushings that wore out — which does not sound Try These Out like your issue).
Like I explained, I'll try and make sure to get some extra pics — ideally this will let you locate your module while! Regards;
