Dealer Only Customizable Features/Carista

Can you post a photo of page 40?

Carista doesn't do much other than try to trick you into a monthly subscription with contrived and mostly worthless "features."

Here at Priuschat we want to figure out how to access dealer only features so DIY folks can avoid their money making scams.

Specifically Toyota moved to the newer Global Techstream (GTS / GTS+) platform for recent vehicles, and dealer-level functions in 2024 and are increasingly gated behind the GTS+ / dealer tooling, subscriptions and authenticated interfaces — so the old “download hacked Techstream + cheap VCI” approach that worked for many older Prius will be of limited use.

Some professional scan-tool makers (Autel, Launch, OTC, LAUNCH GTS bundles) advertise “OE-level” Toyota support, but true authenticated programming usually requires dealer credentials or a paid OEM subscription.

If you'd like to help us figure this out please research the offerings of scan-tool makers and try them out and report back. Also find out about GTS+ subscription options or legitimate J2534 packages (and confirm NASTF/registration requirements). Also see if you can find independent shops that advertise GTS+ access and report back on that too!

As in we want to help people avoid trips to the Toyota Stealerships as much as possible and we need everyone's help to figure this out. Maybe @ChapmanF has some thoughts on the subject?

 

Worth checking if dealer adjusted settings "evaporate" if the 12 volt battery's disconnected. And if so, look into memory savers.

 

Technical library access - including use of GTS+ - is 5 euros for an hour or 25 euros for a day in Europe. Seems pretty reasonable to me, at least compared to whatever a dealer would charge you for anything.

Probe I use with it is the Tactrix OpenPort 2.0 - don't recall what I paid for it, but it's something like $170.

Not prohibitive on the scale of car expenses, I think.

And you get the confidence that you can do almost anything to the car that the dealer can. Exception might be not being able to get access to some software/ECU updates.

 

Anyone got a list of Gen 5 features? I can check them out in Techstream and pull the PIDs so we can add support in the Dr. Prius App.

 

Owner's Manual Excerpt:

 

In the US, the shortest subscription available is two days (but still pretty reasonable compared to what a dealer would charge, especially if you imagine troubleshooting some problem that makes you use the tooling repeatedly in those two days).

Last I knew, only the "security professional" subscription involved checking for a NASTF Vehicle Security Professional registration. Same subscription price as the normal pro diagnostic subscription, but also lets you do security-threatening things, like registering new fobs without an already registered old one.

I don't think you need VSP to do more normal things, even like registering a new fob as long as you have a working old one.

 

2-day* Professional Diagnostic subscription recently went up to $80. Does most everything except programming ECUs and new keys.


*actually more like 3-day; it expires on the 3rd midnight(don't recall if PST or local time), so you can get most/all of a third day if you purchase it early in the morning

 

From your above table, it might be keeping the lights on for 30 seconds, depending on your settings. Did you wait 30 seconds or start the car before starting messing with the buttons?

 

Here is a pretty exhaustive list of the customization settings as they appear in Techstream 18.00.008 for the Prius Prime. I left off the customization setings for driver 2, driver 3 and guest as they are all the same as driver 1.

 

I have Carista and it does do dealer only changes.

You have plenty of time to try it and make the changes you want with the free trial.

I made my A/C compressor quiter and some other dealer only changes.

 

All this technological “progress”…
