2020 TRD SPORT 4X4 CREWMAX OBDII PORT

I have a 2020 TRD SPORT 4X4 CREWMAX WITH PUSH BUTTON START. I am trying to use the OBDII port and jumper wire method Car Care Nut shows to do a transmission service however my OBDII port is missing pin #13 Anyone else have this issue?

 

What exactly are you trying to do? Do you have a link to the “transmission” service?

 

Yes . Here is the link. It starts at about 7min 55 sec mark. https://youtu.be/NUAuGmDGntY
I bought a zurich ZR15S that supposedly had bi directional controls, transmission temp readability, ABS BLEED ETC. None of the special functions worked . I figured it was the tool but perhaps this OBDII port has been purposely depinned ???

 

I went to toyota today do ask about this specific information. The tech sais it's pins 4 and 13 as well. I don't have pin 13 but I have pins 14, 15 and 16.
Pin 4 is CM or body ground, and pin 14 is CANL - Low level CAN bus line. Pin 16 is BATTERY POS. No description of pin #15
Can someone please help me with finding the correct 2 pins to jump for this transmission service?????

 

Pin #13 is TC (Timing Check) to the Abs module.

This pin was removed from the Tundras during the 2018 update. Your truck is 2020 so it won’t have it. Most likely will have to use a scan tool on the CAN lines.

The entire communication network changed drastically in the 2018 update. If you are using an older repair manual some of the info will not be accurate.
