I was chatting with Matt@OEM about these 10-19 parts and he said Japan inventory on these parts ran dry a month ago and now North America Toyota/Lexus parts chains are starting to tighten up as well and even dealerships are beginning to struggle getting these parts. Availability may be sparse for a while. If you are thinking about picking these up and can find availability anywhere you may want to act on it. Not sure when backlog will be caught up.

I know '20+ w/MTS & Crawl adds Auto and Rock & Dirt mode but curious to hear from '20+ equipped 460 owners if they are seeing what is reported here for the Tacoma.

An IH8Mud member added Turn Assist Control, MTS and 5 speed crawl to '10 LX 570 here

'08-'11 LX/LC just had 3 speed crawl

The network gateway ECU was the final piece of that puzzle. Something to consider for '20+ conversions if skid control ECU turns out to be a bust. The fact this version

8911147080

also works with 2019 models makes me suspect it won't be relevant for '20+ conversions. Perhaps in '19 for the updated 4G Enform?

Do you get ALL 5 crawl speeds with the DAC hack?
I'm under the impression that the DAC turns on the CC and only 1 speed.
Can you set the other 4 speeds with the DAC hack?

Acrad

Without additional buttons from mod below it would be single speed only with a repurposed DAC switch.

That's what I thought, but looking at Jackets video of him rolling into his driveway, if you look at when he first activates CC, it looked like it changed speeds from the second position (from the bottom) to the lowest position shown on his dash. I was thinking he changed it.
Since I have the premium version, I wonder if I could use the height control for changing CC speeds? I'll have to check to see if they are momentary switches or not. But they do toggle up AND down with default center.
But I'd like to continue this on MUD, since I'm not on here as often as MUD.

Acrad

It stays in last used speed and you do have to toggle up or down from every step.

The wiring diagrams for that full switch are here and on mud.... probably could repurpose the suspension switch..I just haven't heard anyone doing that yet.

I just added Crawl Control and MTS to my 2012 Base. I did get a lot of ABS noise on a quick test. The install video was awesome! Mad props to that guy!!

Obviously installation costs are in error :-)

Only a smidge. ($12,400 - $14,400)

Finished zero point calibration. Crawl control registered successfully. I noticed after I installed the crawl control box and before zero calibration, vehicle air suspension seemed very rough. After zero point calibration and straight driving, got the suspension smooth. Dont know if its related. Any one who faced this issue?

Acrad

SamLexRXGX: I have not heard of that report before.

SamLexRXGX

The status screen showed "Air suspension Test Mode" during the second step of the zero point calibration. I used the obd safety pin method. Looks like it calibrates airs suspension also. mine is luxury model with rear air suspension.

Acrad

Interesting...my '12 Premium has same suspension setup but I used Techstream as OBD method wasn't tested back then.

Any chance terminal 13 was grounded as well?

I did not do any of these. only used 4 and 12 . Do I need to redo the zero point calibration and include the 13 and 4 as described in this?
