Temp check mode, OBD missing required pins

I have a 2021 Tacoma I was getting ready to drain and fill the transmission and I noticed the pins I need seem to be missing on the OBD port.

Is there another way to put the vehicle in temp check or am I missing something?

 

20 and newer I believe, have a newer, better, easier way to put into temp check mode. sorry, I do not have a link to help you. Ski

Or... You can use one of

Thanks for the info.

It appears to have been under filled from the factory, I drained maybe 2 quarts out of the pan if that.

40k miles on the truck.

 

You don't need to mess with the OBD Port. Just follow the procedure below.

AC60F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSMISSION FLUID: ADJUSTMENT; 2020+ Tacoma
To enter automatic transmission fluid temperature detection mode:
Depress and hold the brake pedal.
Start the engine. [#1]
Turn off electrical and mechanical loads
Slowly move the shift lever from P to S, then move the shift lever to P. (~3 seconds each position [#2]
While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 12 seconds or more. [#3]
Perform #1, #2, & #3 within 60 seconds
Check that the D shift indicator comes on for 2 seconds.
Move the shift lever from N to P.
Release the brake pedal.
Allow the engine to idle until the automatic transmission fluid temperature reaches 35 to 45°C (95 to 113°F). The D shift indicator will come on again when the fluid temperature reaches 35°C (95°F) and will blink when it exceeds 45°C (113°F).
Performing this operation will cause the vehicle to enter fluid temperature detection mode and engine idle speed control mode. In engine idle speed control mode, engine idle speed control starts when the fluid temperature reaches the specified temperature and the engine speed is maintained.

 

I was just trying to figure this out today and low and behold, here is this post. Now that's timing!
Looks like SSMTRDOR did a copy and paste from Toyota TIS. I will attach a copy of that as a print to PDF. Go to the section "(b) When not using the Techstream:".
So, I'm wondering, is the part where you shift from P to S to P even needed? He didn't do that in the vid.

 

Yep! Works like a charm on my 2020. While watching the big D, I had an OBDLink MX+ connected to the OBDII port and was watching the temp. I recorded a range of 97.3 to 115.3 degrees F at 700RPMs. I didn't time how long it lasted, but it was more than enough time for the job.
I wonder what you do if you live in a place like Arazona and your truck has spent half the day sitting in 120-degree heat.
