Crawl control can be used on both up and downhill right? Is DAC for downhill only? I’m curious how steep is the downhill angle it needs to be? A readon for me to head to the local road park (Hollister Hills) and try. Lol

Personally, I would consider adding a rear locker before adding CRAWL.

bbqsoup: Correct DAC is downhill only. It should take much downhill angle to be live.

Surfishing: I hear ya on the CRAWL... if it was just the BCM and the panel and cost less than $500 I might be game but one would probably be in a couple thousand as a guinea pig... just throwing the idea out there for some young lad to try out in the next few years who pieces it together with parts from wrecks.

Notice one probably needs this "Driver Support Switch Control ECU". I think I saw one within the last few months for like $30 as a used part on eBay.

One would need to find just the right dealer who would be open to a non-warranty type upgrade.

Looking at what the 4Runner guy did.. on the GX one would want to utilize a VIN (maybe from an online ad) from a '10-'13 Premium or '14+ Luxury to lookup difficult to research parts.

ObsidianBl posted some good info from that Russian thread.

Not seeing BCM or master cylinder listed to make it go live. All speculation but potentially obtainable for less than $600 retail.

I'm gathering from translation that anyone who has Park Assist has the following support module behind the glove box.

---> 859A1-60010

Multi-terrain select and crawl need module 859A1-60020

Switch assembly with Crawl ON/OFF button and speed control to replace DAC button is ---> 84970-60070

If I understood this correctly, there is pre-wired harnesses already for the crawl and speed control switches, as well as the connectors for 859A1-60020 (assume that will accommodate additional connectors for crawl control), right? For those who had remove the console switch panel for other mods, maybe able to chime in to see if there has additional harness existed. That would be interesting if it can be added easily.

It would appear so. The console switch is a big question though.




Pictures of a non-AVS/airbag switch (84970-60100) / Trying to track down pics of switches to see if connector is the same for all models.

Some of this has probably been stated in other threads. Obviously just more information gathering. Most vehicles I have seen seem to have the full array of Driver Support options if equipped.

It is worth noting the following variations from the 2010 & 2011 model year brochures:



2012 shows this



2013 shows this:




Here is an interesting note in 2011 brochure

Wide view monitor, Crawl Control and Intuitive Parking Assist could be purchased as a standalone option. Is this a unicorn? Maybe..but it seems like similar feature-set to what the Russian thread was talking about.



Here is my real conspiracy theory stretch.... Is there already a support switch module in dash next to my glove box since I have Intuitive Parking Assist? and the other features go live if devices are connected? Could it just be the console switch I am missing? Nothing could be that simple.

Notice in the 4Runner conversion article:

http://tctmagazine.net/spring-2016/2...ntrol-retrofit




Much of the work done in that conversion occurred because he didn't have the physical MTS switch. This MTS (multi-terrain select) selection & display is all done on the center gauge display on the GX. It is just display on the 4Runner.

It may be more plug and play on the GX than implementation on 4Runner.

Just throwing ideas out there

You could be right. I guess the easiest way to know is the see how the connectors behind console with panel between with or without crawl control. If there is a reasonable priced switch panel available, and existing wire harnesses seems fit, I will definitely try to see what happens.
