Crawl control not working

I see it as an additional tool, and not a replacement for all off road scenarios. There are times when the computer may be able to help someone out of a bind, or make going up something steep (on those vehicles where it still works) or go down something hairy where having the opportunity to focus a little more on steering input and observing the trail are desirable. The MT Pro’s and OR’s cost just as much as their AT brethren, so it’s not like we paid extra for it. And, it’s standard on these vehicles, so again, just another tool in the toolbox.

I whole heartedly agree that it makes a terrible racket, which for that reason alone has me only using it every once in a while, just to ensure it still works

A friend of mine did the bury it in the sand trick, and the CC did get it out, so I imagine if someone finds themselves in a sticky situation, at least having the option to let the computer give it a shot doesn’t hurt.

Really interested to see what Toyota says about those with CC’s that don’t work going up hill. “That’s normal” is not the answer and I for one would push it hard until fixed. There’s a ton of YT video’s of CC equipped vehicles going up hill, so it shouldn’t be to hard to come up with evidence of it functioning that way. Hell, if you’re in CT and they tell you it doesn’t work uphill, I’ll bring mine over and prove that it does

 

So in the interest of science, I just used the piss out of the crawl control. On my 19 OR it works uphill, downhill, or on level ground. @Joe jaramillo suggested that the ECT mode may have an effect. It does NOT on my 19. You can engage CC with ECT on or off and turn ECT on or off at will at anytime while using CC with no effect on the function of CC. I drove over 5 miles this AM screwing around with the CC. Was a rather boring and slow experience. None of the dirt trails required it's use but what the hell.....

 

After seeing this thread I decided I'd better test the CC on my new 2020 TRD OR this morning.
I went up a steep incline, down a steep incline, and sideways across a less steep incline, and it worked perfectly!

The noise from the brakes was rather un-nerving, but it definitely works as intended. I suppose that it might come in handy in unusual/extreme circumstances, but I don't see much use for it beyond that.

 

Yes. It would be interesting to try that sand exercise with 3 pedals and traction control. I think traction control is what allows CC to succeed in this case - not the CC itself...

I've also see other videos where CC makes a relatively easy track seem harder than it is (while failing). This same track is then apparently inconsequential when driven with pedals (both with MT and AT)...

I do agree that it is just a tool in the Kit - certainly will not detract from the truck - but it certainly will not help improve anyone's driving skills.

Most people are out there to challenge their skills by having an adventure by getting themselves in a difficult situation (that is certainly not necessary...) and to use their skills to try to get out.

- Then there are Maxx tracks, winches, and tow straps... Does CC replace those other tools? nope.

Should it work on a truck that comes with it? Most definitely!

 

Nice feature, glad I don't have it on my Sport. I would never really need nor do I want to repair it later if need be. I have never needed it nor a locker. I just don't ever push my trucks off road other than the beach or if we ever get snow. If you have it great, just make sure it works.

 

After seeing this thread... I went out and tested mine on my 2020 PRO and I am in the group (CC does not work). The system on my 2011 & 2016 4Runner never had any issues and would crawl over things. As soon as my '20 would come across any sort of resistance it would stop and cancel the system. Whoever goes to the dealer let us know what they find. My production date is 10/19 for what its worth.

 

I can confirm my 2019 crawl control stays on from flat ground up onto a long hill.

I was on a familiar trail that got very muddy in the rain. I could make progress up the hill w/o crawl control, with and w/o locker, but forward progress would also slide the truck closer and closer to a big drop off because the road was off camber. So I would have to back up and try again.

I was starting to think I’d need to call for a tow when I remembered crawl control. Crawl control slowly crabbed and clawed from the flat bottom all the way up the hill about 1/4 mile, w/o excessive slippage toward the drop off. I may never need it again, but I’m glad it was there that day.

 

That sucks. Hopefully for all you 2020 guys it's nothing more than a software glitch or some other easily correctable flaw.

 

My truck is at the dealer today. I will let everyone know what they tell me.

 

Just checked and the date of manufacture for my truck is 10/19 and as mentioned above my CC works just fine.

 

Well, they said that maybe the transmission hasn’t learned my driving style yet. I said ok, but I will be back in 1500 miles. They acknowledged that they tried my old pro and it worked fine!

 

Just another 2019 here. CC works uphill , downhill, reverse , w/ ect no issues. I hope Toyota starts giving 2020 owners a definitive answer on this issue.

 

Thanks for the update. I had about 4900 miles on mine when I posted pictures earlier in the thread. Pretty sure it isn't a transmission learning issue.

 

Yeah, that’s definitely not the issue

 

I doubt this has anything to do with this. I first tried mine after 500 or so miles. Long before the trans had any chance to 'learn' much of anything. It worked then and always has the few times I've used it. I've got 13000+ miles now. Works no different now then when new. Kinda sounds like the dealer blew you off.

 

I'll be keeping an eye on this thread....I used mine once when I got stuck in some mud a few weeks ago but the truck was pretty new to me so I didn't really know to expect. At first it seemed like, holy shit it's working then it did just stop. I monkeyed with it for a few minutes before calling a friend with a tractor. Then, last Friday I tried it on a very steep gravel road just for kicks and it did jump out of CC the first time I used it. I tried it again and it seemed to work.

 

In my experience, the traction control just tries to kill the motor when churning through, or stuck in, deep sand — and you should see how much the shifter rattles when it does!!

After all, with the stick shift, the wheels have to turn at that 500rpm idle at a bare minimum (plus/minus gearing)
Crawl control, with the torque converter, can operate at those near-zero speeds

 

It’s definitely a issue with something on some of the 2020’s. Mileage has nothing to do with how the CC works. Dealer idiots will say about anything if they don’t know what the problem is.

 

I’m with everyone else and do not believe mileage has anything to do with the problem. When I tested my CC I had just shy of 3k on the truck. Also, someone else mentioned turning off the ECT? I don’t believe this is an issue either as I have one of those devices (purchased here) that allows my ECT to be on at all times, so my ECT is always on and was when I used CC.

You may have to call Toyota directly if the dealer(s) won’t help?

If there’s someone close to you with a 2020 and working CC, you may try going to the same place and doing a side by side test to see if there’s something different being done on one vehicle when engaging than the other. I still think it’s a computer/programming issue, but maybe there’s something different in the set up that’s causing it to fail

 

I doubt it also, but my dealership is good to work with. I think the hope is that a fix will be identified soon and they will just be able to install an update. They did say if it didn't work correctly that they would bring in a Toyota Tiger team!!!
