HELP! How do you disable safety features

[jeffd]

I am having a devil of a time in disabling the reverse/rear assist braking when I attach my trailer hitch mounted bike rack. I’ve gone through the menus under PDA and turned SA, DA and OAA all off, and turned Parking Assist off. And still, my passenger and I get jolted by a sudden panic stop as we go down our 20% steep driveway.
Anyone else experiencing this or generally related issues? Anyone maybe discovered a solution(s)?

If you have something installed on the rear hitch, turn on tow/haul mode to disable the rear sensors. You should be able to leave everything else on

I figured this out today. I had the same issue. On the left side of the steering wheel there is a button next to the interior lights. Push it. It kills the 'auto braking'. The truck will still yell at you, but won't slam on the brakes. You can turn off the yelling in the dash settings. I forget the name exactly, I think it's Parking Assist.

I bought an empty hitch plug thinking I would just plug that in when I put on the bike rack. The manual says that would work. It did not. Maybe the 7-pin needs to see current.

Great post! And yeah, I don’t care at this point if all it does is yell at me, lol. Trial run later today, fingers crossed.

I did this with my Audi when I have a bike carrier attached. I needed to use a 7-pin trailer adapter with a tester (like this one Amazon.com). With this plugged in the car goes into tow mode and the sensors don't go off. I think the tester is enough for the car to see a current.

Curious to hear how it goes for you. I like to leave my bike rack mounted during the non-winter months.

Used the button to the lower left of the steering wheel that turns off the rear park assist braking. And just as previously posted, it still hollers at you but no unexpected panic stopping.

The pA assist button on the lower left of sterring wheel deactivates it

My concern about using a couple of these options is whether the truck thinks it’s actually towing something. I’m not a mechanic or automotive engineer so I don’t know the right words to use but I believe it changes some thing so that truck stays in lower gear for longer thinking it needs more torque to get moving. I know that when I hit the tow/haul mode on my LX570 and Tundra before that, it was almost like a turbo boost and helped with acceleration. Maybe someone can help translate that to “auto-speak”.

If you're asking about "Tow/Haul" mode....

It firms up the shifts....

In overly simplified lay terms: When in normal driving mode the transmission shift curve is long and smooth thus improving fuel milage. as an example (for the haters..... just an example the numbers are made up) shifts into 2nd gear at 1500 RPM, 3rd at 2000 RPM, 4th at 2200 RPM, 5th at 2500 RPM etc...... Highest MPH at the lowest RPM

In Tow Haul mode the transmission doesn't care about fuel mileage, it cares about power/torque (again just an example) it shifts into 2nd at 1600 RPM, 3rd at 2200 RPM, 4th at 3000 RPM, 5th at 3500 RPM, etc

It holds it in a lower gear longer at a higher RPM thus providing maximum power/torque for the amount of work it's doing at a given speed. When loaded and needs plenty of power to maintain a certain speed, it will do it in normal drive mode but will most probably be hunting gears (shifting into a higher gear and on slight incline increase, shift into a back into a lower gear, repeating that process annoying so.... etc) when in tow haul mode, it maintains the lower gear and higher RPMs for longer.

"hunting gears" basically that means the transmission is shifting to find the best RPM to maintain the MPH asked of it by the driver. The 2020 Tacoma has a crapbox transmission and is always looking for a gear even when empty and going up even modest inclines. I sometimes manually lock it into 6th when traveling in hilly highway terrain.

Hi. Does anyone know how to stop the rear hatch door’s constant beeping when you open and close is?

You don’t. An alert tone is federally mandated for automatic closing doors

Maybe Carista?

I bought this and put it on today when I had my mountain bike on the back - still screamed at me. Maybe I didn’t plug it in correctly? I plugged in the round side.

I also turned off parking brake assist and hit tow haul mode - just fyi - and still screaming / beeping

Oh no. Sorry to hear that. On my Audi it switches to tow mode (turns off blind spot indicators and puts the back-up camera into "trailer" view) when plugged in. But for whatever reason that car needs to be off when I connect the adapter. In the LC user manual it says that the parking sensor and brake assist is turned off when a 7-pin connector is connected. I guess it doesn't recognize the test lights as "connected". Just curious - do the lights on the adapter light up when you test the turn signals?

For manufacturers. Owners can and should modify this to suit their preferences.

I’ll test this and let you know…

Maybe Carista?

If you use Carista for the Land Cruiser, let us know your results.
I used it for my 24 Tacoma. It was a little buggy as far as remote starting the truck with the key fob and putting the windows are down although they did work. I just had a little trouble getting the sequence right because I didn't explain it.

I was able to shut off that ignoring seat belt ding ding dong dong ding ding dong dong dong ding ding dong when the driver seat belt is unhooked. I only unhook it when I'm approaching my driveway or or I start taking off because I never put it on until I start moving or driving slow off-road. Just a habit I could never get out of.

I also changed the automatic turn signals from three blinks to five blinks when I hit that turn signal arm momentarily to change lanes.

When I hit the window switches to go automatically up, the passenger front always stopped a few inches up and I had to do it a second time. I deactivated everything except the tone, it took a few weeks before it just started working good again. Maybe or maybe not it was related to the Carista.

I’ve been using the Carista for years and I believe it’s rock solid. Toyota‘s technology, the digital key, the app, and some other things in the multimedia center is not ready for prime time. Still very buggy I feel like an alpha tester I don’t even think it’s ready for beta.
