CARISTA for 5th Gen 4Runner – OBD2 Bluetooth Adapter to Unlock Hidden Features on Your 4Runner

Carista Electronic Customization 4Runner

OBD2 Bluetooth Adapter and App: Diagnose, Customize and Service Your Toyota

One of the huge selling points that drew me to the 4Runner was its ability to have a rear window that rolls down. With the twist of a key, I can open and close the rear window from outside the vehicle. I just wish the other windows had the same ability.

After checking the manual, I found that they can!

The Toyota 4Runner Manual lists a variety of customizable features that you can change, however says, “Programming these preferences requires specialized equipment and may be performed by your Toyota dealer.”

Sounds easier said than done, sometimes it’s hard to find time with a busy schedule to visit the dealer, and wait for them adjust a few personal settings.

Toyota 4Runner Customizations

During a warranty-covered oil change, I asked if they could adjust a few features while it was there. I was told I would have to book a separate time because the only one tech that performs these tasks was unavailable.

Some Toyota 4Runner owners mentioned that some dealerships charged a labor fee for adjusting these customizations, while some were able to get theirs done for free.

All of this research led me to this amazing little product, Carista, that not only lets me change those features around my own schedule, but does so much more.

The Carista app also has the ability to run diagnostic tests on your vehicle, allowing you to find out which fault codes are trigging a “Check Engine” light, as well as their meanings. Though the app you can reset, clear codes, and perform dealer-level electronic diagnostics of all modules in the vehicle.

The Carista OBD2 Module also supports third-party apps such as OBD Fusion, Dash Command, or Torque.

Apps like these provide an advanced display for engine and sensor data (e.g. transmission temps, MAF, battery voltage)



Download Carista on the app on the App Store (Apple) or get it on Google Play (Android)


Carista works by plugging in the module into the vehicle’s OBD2 connector port, usually located in the driver’s footwell area. Locate the port, and plug your adaptor in.


Connect to your device via your phone’s bluetooth


The app should prompt you, that if you would like unlock the apps full capabilities, you will need to pay for their subscription. To redeem the Free 1-Month Trial you will be presented with a purchase option. Select the one with the Free Trial to unlock all the functions of the app. (During the 1-Month Trial, or after making your customizations, you can cancel your subscription)


The CARISTA home screen gives you three service options to choose from, tap ‘CUSTOMIZE’ to begin changing the personal preferences of your vehicle.

Example: From here on the vast customizable preferences are yours. One main feature I wanted to add to my vehicle was the option to roll all my windows down, from just the click of my remote. Making the adjustment was as simple as scrolling through the list of features, selecting ‘Open windows and sunroof via long-press on remote – OFF’ and toggling it from OFF to ON. Click ‘SAVE’ and you’re done!

Just tried this out and all went well! Thanks Frank. Cheap, fun, easy mod!

This is a great find!!!

Does anyone know of an OBD plug-in to bypass the TPMS?

I enjoyed reading this article. And you pointing out all the different features that you can change. There are a few things I’d like to change also. Thanks for the information.

Do these settings apply to all 4Runner trims? I have the base model SR5, will the remote window setting work?

Yup, I just did this on mine.

I just got this for my 2015 4Runner and tried to get the windows to go up and down by remote but it did not work? I can use the key to put them up and down. Also the sunroof and back window do not work with key or remote.

Same thing here. I can only get my windows to go down via remote. I assume that’s normal?

Remote not working at all for me.

July 16, 2019 1:04 pm

Which button on the remote should you push to get them to go down. I tried both but maybe i need to hold longer can’t get it to work at all.

Question: Are the customized settings retained if the vehicle’s battery is disconnected and reconnected? I’d like to just have to program my configuration once and not every time my battery is disconnected.

Super slick. Super easy. Took 2 seconds to download and activate app on iPhone. Super easy to use and modify dealer features. Awesome buy!

January 30, 2019 11:06 pm

I was looking at that but I’m trying to stay away from adding more lights hahah. I’ll keep digging. Thank you

January 30, 2019 4:07 pm

Ah I see. I guess I’ll have to dig a little deeper on how to keep them on until starting up the car

January 30, 2019 3:10 pm

Coming-home lights duration – 30 SECONDS… is this when you disarm via remote? If not is there an option to do this. I’d like the courtesy lights to be on for my wife when she goes to the runner at night

For whatever reason my 2016 4Runner Trail would not let me turn off the Eco light even though there was an option and I opted to turn it off. Tried toggling multiple time but no luck. Unfortunately that was the one thing I really wanted to turn off.

The 2020 TRD Offroad Premium doesn’t have that DISP button on the steering wheel. Does anyone know how to disable the ECO light on the 2020? Thanks

November 20, 2018 3:40 am

Thank you for this! Fixed so many of the little things I had wished I could change easily. Windows down with key fob and increasing the rear window wiper intermittent time made my day. Plus I already had a WiFi OBDII device and the Carista app worked with it. No need to buy the Carista OBDII device.

Is there a way to unlock all doors with single push of the unlock button?

September 20, 2018 9:32 pm

What does this one means?

“Unlock all doors when driver’s door is opened”

September 26, 2018 12:24 am

Gotcha. Well it never hurts to press the unlock button twice, more exercise for the thumb. =)

Sorry if this was covered…

Can you use your phone to unlock the doors if you left your keys inside the locked car?

Will you be able to still use this feature after the trial membership ends?

So glad you posted this! Was told I had to return to my dealer where I purchased to customize the remote settings and beep volume. Just ordered one!
