2 sets of TPMS with TechStream??

Can 2 sets of TPMS sensors be programmed into the ECU with the TechStream software? How? I see how to replace the 4 sensors with new codes but not how to save the existing and add 4 more. Also is there a factory alarm function in the ECU that can be activated with the software? I recall reading someone activated it but I can only find the immobilizer function and not an alarm.

 

I know that on my '06, one can program a second set of sensors with a Snap-on scan tool, but I'm not sure about how to do it with Techstream as I gave up trying to get mine to work with Windows 8.1. You still need to manually select which set when swapping winter / summer wheels, if that's what you're up to.

The newer TPMS systems may be different, but I'd bet there is a way to do it with your '13

 

Yup, that's exactly what I'm after. I run studded snows on the stock steelies and have aftermarket wheels for the summer. It would be handy to have the codes programmed already. I have yet to figure out how to enter and save 2 sets. It certainly isn't inuitive.
I run my TechStream on an old laptop the was going to be recycled running XP. Slow as molasses but it does the job.

 

I wasn't able to. It only allowed up to 5 sensors.

 

I've recorded the codes off the summer tires. Once I get the winter wheels on and have the light turned off, I'll be able to get those codes through the PC. It looks like I'll have to manually enter each set when I flip the wheels.

 

When you select the TPMS module, there's a menu option on the left that'll show the current codes along with the current air pressure and tire temp. It also shows you the threshold pressure where it'll trigger the light.

 

From the reading I've done on the forum, it is not possible to store two sets of TPMS codes in the computer of a Tacoma. IIRC other models (cars, I think) of Toyota can.
