Update: Installed the new switch, without doing ZPC (since I don't have the OBDII connector and TS).
1.) Airbag suspension switch works. I can raise/lower and turn off.
2.) Suspension dampers: Comfort/Normal/Sport. Not sure if this works since I didn't drive it, but I think it does.
3.) 4L / 4H switch works and it does activate my factory pano cameras and it video feed works.
4.) MTS Switch On/Off: Doesn't work. Switching 1-5 speed switch doesn't activate anything, even DAC light doesn't pop up.

I'm going to leave the new switch installed until I get my OBDII wires. I don't use DAC anyways.

Next Step: I already have the OBDII connector in order. Should be here Tuesday and I'll try to install TS and see if I can perform ZPC. Let's see if this will work.

However, I'm not sure if I'm missing any wires from the switches to where it goes. Here are the pictures of my 2020 Luxury console wires. I marked the the pix with red arrows, on pins that I notice that are missing wires. However, I'm not sure if those pins are also missing in the 2020 with ORP. So if anyone that has 2020/2021 w/ORP, can take a picture of these connector, that would be awesome.

This is the connector that connects to the switch itself.



These are the 3 white connectors that connects to the console.

This IH8Mud member was able to use TS on '20 to do ZPC but this was done on base/premium without wiring so it wouldn't work

just finished TS/VM setup on my laptop. just waiting for the connector and I can see if I can be successful on ZPC

Added a new CC switch and did the ZPC this weekend. I seem to notice an improved throttle response. Is this possible or is it my imagination. Change seems similar to sport or sport+ change on previous RC350.

Did you perhaps disconnect battery and vehicle is learning driving habits again?

Update on my 2020 GX 460 Luxury: Techstream version 12.

So I got the cable yesterday and hooked up it. TS recognized, since it pulled the VIN, however I had to enter what type of car it is and I can only go up to 2018.

I followed this guy's video but I don't see Utility in mine.

I can only see ECU Reprogramming and that's where I can see ABS/VSC/TRAC, however, I couldn't do anything with it. I was getting a red "?". Something about "Network error"?

Then, I had a scare because after I gave up, an hour later, I couldn't start the car. But I just killed the battery so I had to jump it.

Here's what I can see.

I also sent a message to the guy in Ih8 to see what version of TS he was using.

This might be a weekend thing, as oppose to just a couple of hours thing. haha

Didn’t disconnect the battery. But not aware of any re-learn process. Thanks for the idea, I will watch for changes.

Update: I was able to get v14 of TS. (I was sent an email with a .pdf file from the seller of Amazon, go by WashingLee).

I was able to Reset Memory then these error message comes on my dash.



Then followed then followed the CC instruction but when I press the CC On/Off button, nothing happens. Only ABS is flashing. I was getting C120A trouble code.



I reinstalled the original module and followed the ZPC then DAC instruction and it worked properly and cleared the codes. No more error on my dash.

So I don't know what else to test.

Acrad

I was concerned logic might be baked into skid control ECU. Assume you are turning vehicle off between the ZPC reset (Reset Memory) and calibration?..but you mention getting DAC switch back working so that would need to be the case. Just thinking out loud.

Looking at IH8Mud thread this is model # on a 2020 base/Premium & appears the same on your Luxury on post 1121

89541-60C20



It seems Luxury w/off-road is 89541-60C10

This has never mattered in the past but that may be the case this time. Post 1118



Wonder if there are any wires missing from the switch to A-Pillar base?

eNx

it'll be interesting to see the wires from the switch with ones that has ORB. My post #1153, posted pictures of the wires from the switch. If it's the same as the one with ORP, the next move will be getting the Skid Control ECU (89541-60C10).

eNx: I've PM'd a GXOR member with '20+ who may have pics from a Premium and may be able to obtain pics of a Luxury w/ORP as well.

Acrad

Looks like '20+ crawl/MTS switch leverages pins 3,5,6,9,and 10

Acrad

EDIT: Sorry.. looked back at your pics... no SLIP but this apparently need occur. It also sounds like the airbag sensor is supposed to reset as well with this TS reset.

Was the SLIP light flashing after you did the ZPC? or did you just see ABS?

Did you see both codes C1210 and C1336?

Acrad

Do you know what version of TS 14.x you are using?

I think production on the '20s started last week of August 2019 so probably want to use 14.30.023 or later.

the SLIP light was not flashing, only the ABS, when I did the ZPC. I got C120A every time I did the ZPC. But when I install the original module an follow the test mode and turn on DAC, then the Slip light, ABS, and DAC light were flashing.

However, at one point I got two error codes one time but didn't see take the picture of the codes.. so not sure what they were.


I'm assuming when you say SLIP light.. you mean this right?
