Zero Point Calibration - NEED HELP
Okay so I have looked around on the various pages about the zero point calibration steps and how to reset the whole thing. I plugged a OBD2 tool into my 4runner and cleared a code after I replaced my spark plugs and everything works fine however I set the VSC OFF / TRAC OFF lights to stay illuminated.
When following the first step, pins 4 and 14 are jumped 4 times in 8 seconds or less I have my ABS light flashing and the TRAC OFF light goes away however the VSC OFF light stays illuminated. I cannot complete any further steps of the zero point calibration process.
Does anyone have any help they can provide to me? I have searched the forums and found no solution to my issue. I have no check engine light or any other problems and ABS works fine. I also made a video of the issue I am having. Please and thank you everyone!

It's a little hard to tell from your video what your complete procedure is, but I suspect you may be missing some steps. Attached is the Toyota service note as to how to do this. The instructions for using the SST method (shorting pins 4-14) are toward the end.
BTW, if you have a 2004 or before, it is not uncommon to mess up the zero point calibration when plugging in an OBDII tester. Has to do with the OBDII tester mishandling the older protocol used by 2004 and before 4runners during the ID phase, and resetting the ZPC in the process.

I had this printed out and when I got to step 3 -
"Using SST 09843–18040, repeat a
cycle of short and open between
terminals Ts and CG of DLC3 4 times
or more within 8 seconds. Verify that
the VSC indicator light is lit indicating
the recorded zero point is erased."
... the TRAC OFF light turned off, the VSC OFF light stayed on but the ABS light came on and was flashing.
I continued all the steps but it never reset itself.
I never got the vehicle to complete anything after step 7.

Have you ever performed the steps of calibrating? I do know the difference between the 03 vs the newer 05 model and the different steps of each but in my video when I complete 4 shorts in a matter of 8 seconds or less, the ABS light flashes and the TRAC light turns off but the VSC stays on. Is that the correct step? It doesn't seem to continue to work. Maybe I have to do it several times before it gets it right? I saw some people had to perform this like 8 times or so until they got it to work.

I performed this process on my daughter's '04 last spring, and it worked no problem. Make sure after step 3 (doing the 4 shorts in 8 seconds) that you turn the ignition OFF, disconnect your "SST", and then turn it back ON again. Then you have to wait 15 seconds for the VSC light to go off, wait at least 2 seconds, and then power OFF again. I haven't seen you mention those steps, so I wanted to emphasize that. You can't skip any of the steps.

When you say disconnect the SST, do i completely remove it out of the OBD2 port? I did all the steps but I couldn't get the car to do anything past shorting it 4 times. If you recall did the ABS light blink like mine did when you performed this?

I think i read something recently that someone was having the same issue and it turned out that the pin location on the odb2 port was not correct

Yeah i checked the pin location and it all seems to be in order. I cant seem to figure out what the issue is. It blinks the abs light and the TRAC OFF light goes away when I connect the two together 4 times in a row and not the VSC light, that stays lit.

You have never said or confirmed that you did what Ron posted above...
Did you....after doing the 4 shorts..turn off the ignition switch?...and then disconnect your "SST" (i.e. remove the jumper wire from the odb2 port)?...and then turn the ignition switch back on?...wait 15 seconds for the VSC light to go off?...wait at least 2 seconds?... and then turn off the ignition switch again?

I actually never fully disconnected it from the port itself, I left the two wires in pins 4 and 14 IN the port itself, but never fully took them out when turning the car off. Maybe that is where I messed up at. I will have to try that procedure right after work or maybe on my lunch break.

If you had 2 wires, one in each port and were touching them together to short out the ports, you were doing that correctly, BUT the 2 ports need to stay shorted/connected until you turn off the ignition switch and then disconnect them, is that how you did it?
No reason to completely remove the 2 wires from the port if they aren't touching/connected.
Edit: Also if you get the steps done correctly up to the point that Ron posted without having the issues you have been having, make sure you do the last 3 steps (9, 10 & 11) to confirm the Calibration worked...
8. After ensuring that the VSC warning
light remains OFF for 2 seconds, turn
the ignition switch OFF.
9. Connect the terminal Ts and CG of
DLC3 using SST 09843–18040.
10. Turn the ignition switch ON.
11. After turning the ignition switch ON,
check that the VSC warning light
is lit for about 4 seconds and then
starts quick blinking at
0.13 second intervals

Here are the complete steps and what happened that I did.
1- while car is on level surface and steering wheel straight and ignition off I plugged two wires, one in 4 and one in 14
2- turned the vehicle on accessory and tapped the two wires together 4 times and then left them apart but still plugged in the ports and then noticed the TRAC OFF light go away (VSC TRAC still on) and ABS light began flashing.
3- turned vehicle in off position and then back on and waited 15 - 20 seconds ( TRAC OFF light on and VSC TRAC light on (No ABS light flashing anymore) the lights never shut off.
I thought the lights were supposed to go away after 15 seconds if I remember correctly.

Yeah i was never able to get it successful to continue onto these final steps.
EDIT: Are you saying during the steps of shorting them out 4 times in a row that the fourth time needs to stay connected and then turn the car off to proceed to the next set of steps?

You need to turn the ignition switch to ON, not just assry, just don't turn it to start.
And yes keep them connected until you turn off the switch.
