Here is calibration guide. You can either do this with Techstream or a wire plugged into a couple connectors on the OBD port.

Now I understand from Russian video the guy is keep putting the SST in and out while couldn't understand what he was talking about all because it needs to be do it 4 times within 8 seconds to clear the memory

Some of my skid control ECU/Master cylinder version concerns are less now. Found this on someone trying to convert an FJ. It lacks the Driver Support Computer so a different animal getting it working there but on this post it seems the skid control ECU attached to the master cylinder is possibly informed by the "Driver Support computer" of vehicle capabilities. In this instance after a master cylinder is replaced or the calibration reset has been performed.

So, if i am understanding correctly, on most of GX, the Downhill Assist is already exist, then it is not necessary to even do zero point for skid control EUC at all. since all the sensors and yaw control are all have been calibrated. Right? All it might need to do is the calibration of Crawl Control part......

On all GXs without crawl control they should have the DAC calibration profile in effect. Crawl Control models have their own calibration profile. DAC and CC can't coexist so in order to migrate to the CC calibration you have to erase the DAC one. In that Prado thread it seem if I plug in 859A1-60020 the MTS option will be available in dash menu but it actually won't don't anything since the calibration for CC isn't live. Not sure if 84970-60070 has to also be plugged in. Not sure how the camera stuff will work with MTS since that will be absent but is activated when in effect.

I guess we'll find out soon enough... I thought I saw posts on .ru sites that many weren't successful unless you blew existing configs away and calibrated everything at once. It didn't take well to an incremental update apparently.
The guy that converted his 4Runner said in article
"Once everything is hooked up and back in place, you will need to do a Memory Reset for the Skid Control ECU, then a Crawl Control Calibration and Zero Point Calibration. It is important to do the memory reset otherwise the crawl control calibration will not work.

I'm thinking the skid ecu might squash this mod but we'll see. I plan to try it.. if it fails I'll plug everything back in and recalibrate for DAC. At $1500 price point for all parts here I'd be looking for air locker options.
The '10s got their skid-ECU flashed for the recall.

I was fully reading through that long 138 or so page Russian thread last night and noticed a few things
• There a few models of Prado that either are not compatible or even lack the wiring
• In other markets they appear to unwind the options further. If some countries there are models without crawl & MTS but Radar cruise is present. Apparently this model that comes with radar cruise can't or hasn't been retrofitted yet.
• It does appear to come down to the skid control ECU but since no one has publicly posted about converting a GX 460 "for crawl" we don't know yet. My 020 module shipped from Japan today. Still waiting on the console switch.

Looking for '10-'13 Base, Premium and Premium w/Driver Support skid control ECU #'s. All trims and years '10-'13.
I am curious if they changed PN's on all model years and trims. This is the black box attached the brake master cylinder that has brand name Advic. The number above bar code is the model#. Mine is 89541-60350.
Steve from the 4Runner conversion is helping me with some research on this too.
Thanks!

Steve pointed me to this site if re-flash ends up being needed. I will be reaching out to them for thoughts as well.

Reprogramming the ECU (engine control unit) is one of the repairs we’ve had to send to a dealer in the past. Without the software and the tool to do the reprogramming, an independent, no matter how well trained, can not do an ECU update. Thanks to Toyota’s excellent new attitude, we’ve been able to buy the factory scan tool and software and we can install ECU updates here at Art’s Automotive! This is a Rav4 that had a check engine light and a code P0420 (catalyst efficiency code). There was not a problem with the catalytic converter, the computer was simply being over-critical in it’s analysis of the converter’s performance. Toyota realized there was a problem, rewrote the monitoring software, had it approved by the US EPA and the California Air Resources Board, then made it available to dealers and independent shops via download or CD. Failing to follow the reprograming instructions carefully can make a paperweight of a $800 computer, so it’s not a job for impatient mechanics or Toyota novices.
Having the factory scan tool also provides access to more information and testing capabilities than are available using a generic OBDII scanner. OBDII is a specification for access to diagnostic information from the ECU. All manufacturers must meet the minimum requirements of the OBDII specification. However, manufacturers also add proprietary diagnostic capabilities to their computer control systems that are accessible only with the factory scanner. Toyota’s willingness to sell the scanner and scanner software to us has made our job a lot easier. Systems inaccessible with a generic scanner, like SRS (air bag), ABS (anti-lock brakes), and many others can be inspected using the MasterTech. There are also many bi-directional tests that can be performed to quickly check system operation without disassembly and hands on inspection. Anything that saves time while paying for by-the-hour diagnosis makes everyone happy.

Repair – We Can Flash Toyota ECUs
In 2005, Toyota promised “an era of unprecedented cooperation with independent repair shops”. Part of this new philosophy is providing access to all of the tools and information available to dealership mechanics to independent mechanics. Information in the form of repair manuals, technical service bulletins, campaigns, and even Toyota’s dealer training programs can be accessed through Toyota’s TIS website. Special tools and software can also be ordered through TIS.Reprogramming the ECU (engine control unit) is one of the repairs we’ve had to send to a dealer in the past.

Looks like my CC console switch just shipped from UAE... the 020 left Tokyo on the 10th.
