I'd check your Significant orange wires as you might be having +5VDC logic since the lights are approaching around the sprint. The +12VDC is used for the encoder motor — Examine to ensure that you have +12VDC at the two the large orange wires (They are really right beside each other… and There's two big black wires beside them which can be ground). Notes: All black wires are floor — all orange wires are energy (scorching). There is a 10A fuse (#fifteen) for the 4WD procedure, located in the fuse panel. There exists a 20A fuse, Situated under the hood, that is definitely also with the 4WD method (I’ll should search for the fuse variety). The 4WD technique also pulls within the 10A courtesy lamp fuse (#ten).
Okay, the module location — I'm able to’t definitely describe it much better than I did for the final remark poster, but in the event you skipped that element… sit within the passenger seat — swing your ideal foot backwards and forwards when maintaining your heel on the floor — you’ll strike your still left foot A method, and also the plastic panel where the module is located one other way. Some older pickup trucks had a “vent†pull tackle Positioned there, if that can help! As to the cold resulting in the situation — may very well be. That’s the issue — there are numerous issues it could be. There may be, what is referred to as an “encoder moduleâ€, around the side in the transfer situation that controls which method you might be in (2, 4HI, 4LO) — if water received in there and froze, it could be protecting against the encoder from switching modes.
The very first thing I would do is disconnect the battery and Allow it sit for any 1/2 hour or so — then reconnect the battery and cycle the ignition from on to off 3 times — This could reset the TCCM.
The cable connects to a “pin†within the differential. With cable disconnected from the “pin†to the diff. I am able to manually shift it in and out below one/four″ in. This should pull out or push in closer to an inch or so correct? Could this pin be flanged on another end, not making it possible for it to drag out, or is there Another problem. Must I even open the diff. or merely swap it.
The, you need to attempt to put it in 4WD and see if any on the wires transform (they must get rid of their ability) — you will have to do this many situations to examine the assorted wires — and an assistant will be pretty helpful! If you’re click not getting the above outcomes, Check out the same wires at the TCCM as find out if the results improve.
While I don’t actually have any working experience with the situation you explain, it seems like a swap / sensor to me. I do know There's a pace sensor that stops you from Placing the method into 4Lo while you're traveling in a velocity of increased than 5MPH (8KMH) — if that is the scenario, the 4Lo light-weight must flash until you slow down to below 5MPH, then it should really drop into 4Lo.
I am aware I’ve in all probability just rambled on and informed you nothing — nicely, that was basically my considered procedure when seeking to come across a dilemma. I'm able to only hope it served. Allow me to know how you make out. If I imagine anything, I'll update this put up.
Thanks for your update — that’s what we choose to listen to! I’m happy to are in the position to enable maintain a number of of Those people greenbacks as part of your wallet — Particularly at Xmas! Best Regards;
I had been fairly delighted whenever they held, that’s needless to say! I mounted the module back within the frame, reinstalled the kick panel and my four×4 was again in business enterprise.
com or even acdelco.com . No person is listing a module regarding four wheel travel or transfer situation. If any person can help with a supplier of the portion, be sure to e mail me at [email protected] . Thankyou, Dale
) The 4lo light justs blinks continuously under no circumstances goes in only goes back again to 4hi. I in this article the clicking Along with the TCCM And that i also listen to the encoding motor Doing work also.
Hmmm… might be a number of items. Initially, if you can find into 4Lo, points probably aren’t as terrible as they appear — this, essentially, lets you know which the components within the program are working.
Argggg.. Could it's the cold? It's been underneath freezing for 2 weeks now and to compound The problem I don't have any heat both within the vehicle.
The subsequent matter I observed was that you choose to mentioned the lights on the dash will flash if you press 4Hi — this informs you which the button for 4Hi is Performing, plus the TCCM is accepting the signal from it. So, it boils right down to a challenge somewhere in between the TCCM plus the encoder motor — I'd personally suspect the TCCM — possibly wiring, or probably a nasty TCCM.
