Default 2005 GX 470 zero point Calibration

I recently got suspension done from Toy connection. When parked, the VSC/TRAC lights are off, however when I start moving they light up.

Without TEMS fuse, they are always on
With TEMS in they come when vehicle is moving. Engine bay fuses are already out. So not that problem. I even pulled the relay.

So I am thinking about doing calibration.
Im unable to confirm which pins are TS and CG

I searched online, and pin outs for almost all lexus vehicles from gS to LS came, but GX 470 2005 is elusive.

I need to short TS and CG first 4 times, and then put vehicle in ignition with them shorted.
But before doing that, first I need to find the pinout. Does anyone have service manual? If not, I will go back to toy connection again and ask them to do it for me. I think they should have techstream, right?

Have you checked the zero point calibration of the 4Runner? They should be the same given the platform similarities.

The 2005+ will probably use the later steps to do ZPC.

Unfortunately pics are no longer there, but will the same pin layout as the older 03-04 models You use different pins on the later models.

Pin layout is in the is PDF , just scroll through it. (but you will probably find a few of these diagrams on the forum if you search).

I went back to Jeff, and he connected this big scan thingy (Snap Vertus I believe) and calibrated many a few systems. Lights off, but I have to live with my "off" light blinking. TEMS has to be left back in otherwise ZPC will be a problem.

I also researched pinouts and its not uncommon for pinouts to change with years. Did not want to take a risk with that. There was some confusion regarding second pin being 12 or 13.

First on is "4".
However second is a doubt. So decided to head to jeff and it took 2-3 minutes.

That shop is a Toyota powerhouse. I guess I know where I am going to go for most of the repair work!

Yeah, they are pretty good at Toy Connection.

The distinction is pretty simple 03-04 has the older pin layout whereas 05+ has the new pin layout.
