Rudy states: March 24, 2008 at 3:38 pm I'm acquiring an issue with my 4WD not likely into 4HI, I push the button and nothing happens. I set the truck in neutral and strike 4LO it goes in, then I press 2HI and it goes again. After i have it in neutral and press 4HI both equally 4HI and 4LO lights flash after which goes back again to 2HI. I read through that when you jumper pin 13 on the data hyperlink cable to ground, then flip essential on the ON posture the lights within the 4WD buttons flash a code, so I attempted it and confident ample a code of 2 flashed meaning motor/encoder failure.

Alright….I just dropped my 4WD looking to recover from the snow in front of me in my parking House at work this early morning. I received trapped undesirable four situations in the last one/2 mile ahead of dwelling And at last needed to wander the final one/eight mile. It took me two hours to have household (about 5 miles!!!). Maybe they must have plowed the streets??? My one particular son in law thinks I may have tried using it in reverse. He provides a Ford that gained’t allow 4WD in reverse. Is Chevy exactly the same way? I keep in mind acquiring it in 4HI then striving 4LO but at 1 level both lights have been blinking now they don’t gentle in any respect. I just utilized 4HI a couple of days ago but in no way attempted 4LO until eventually today.

Unfortunately, I have not had knowledge using your specific challenge — but it does sound like it could possibly certainly be a) a similar trouble as I was obtaining (ie. inner gears / forks of the transfer circumstance not enabling total shifting from a person manner to one other), or b) a front axle switch challenge (which is located in the Electric power Command Module (PCM) — but that’s about all I will let you Together with the PCM as I don’t even know where it’s Positioned).

It’s attainable the method is partaking by itself. Even so, 4WD engages WITH vacuum, not without the need of — accordingly, you'll have a nasty vacuum swap and that is enabling vacuum through when it shouldn’t. Now, why the lights are heading out, which is odd. I wouldn’t Consider the program would “point out” 4WD when it wasn’t physically set there — meaning, In case the 4WD method DID come about to kick in because of vacuum, the TCCM would have not gained a sign To place the process into 4WD and therefor would not move the encoder motor, or activate the 4WD indicator lights. In case the 4WD program is kicking in on account of vacuum, the sole serious matter to become impacted might be the front axle, that's what is controlled by means of vacuum.

Should you look at the schematics, you are able to see the motor is just “managed” with the TCCM via sign wires. I suppose it’s feasible that if one of many motor wires were for being shorted it might induce damage to the TCCM — do I think This can be the case?

It looks like the vaccuum is coming from the module within the transfer circumstance but I had been undecided the way it all labored together. Any one have any tips? I don’t Have a very provider manual for that truck, but am not against getting just one if it's a superb area on problems capturing the 4wd system.

Incidentally, the supplier instructed me that 4Lo typically can not be turned on Until you put the vehicle from the neutral. If somehow car goes into 4Lo by by itself, just set it during the neutral position, and you'll switch out 4Lo.

Unfortunately, I am able to’t provide you with a definitive response for your problem, but if I had to mention, I’d search elsewhere, in addition to your TCCM (encoder or transfer scenario)… but however, I’m not a mechanic possibly… so I am just guessing!

However, I don’t know the responses to most of one's inquiries — I am able to guess, but that’s what it’s gonna be, a guess.

Since October is key fishing time on NC Outer Banking institutions and 4wd is essential, can I manually set vehicle in four hi by pulling the cable that goes into actuator? for a temporary resolve. Back diff seems to lock but is tough to inform around listed here, also flat and as well dry.

Next, your sprint buttons will come out on the dash with tiny exertion — pop out the module and Test the wiring harness over the back again of that. I’ve read of folks encounter issues with the actual buttons.

Indeed, the website remains to be active — truly, I'm able to’t imagine how Lively (for my minimal web site internet site) it has been in the previous couple of weeks — and all with regards to the Blazer!

It Seems extra like “mechanic discuss” to me — but who am I? What precisely do they assert being the issue Using the TCCM? What Element of it truly is undesirable?

You aren’t finding any flashing of the lights in any respect read this (once you test to engage 4WD)? There must only be a single light on at a time (indicating which vary you might be in) — numerous lights should really flash after you check out to engage 4WD (either Hi or Lo). If you are trying to have interaction 4WD along with the lights don't alter (ie. no flashing), I would suspect an issue with either the wiring to the TCCM or the TCCM alone is lousy.
