TPMS

Have to in the US.

 

all toyota's have tpms, are we missing the actual question?

 

What is this tpms you speak of?

 

Tire Pressure Monitoring System.

 

Earlier in the year, the Combination Display in my 2009 Gen II Prius failed, and the local dealer loaned me a brand new Camry for the 3 weeks (!) it took them to get and install the replacement unit (see other threads), during which time I noticed that the TPMS system in the Camry was more sophisticated than that in my Prius (showing each pressure in the individual tyres), but as it didn't cost me anything, I wasn't complaining!

 

The strange thing is,that Toyota uses the same system as Lexus uses !
The only difference is,the exact tire pressure levels are displayed on a Lexus but not on a Toyota although our Prius or any other Toyotas BC using TPMS also is fully aware of the exact figures !
I have allways been wondering why nobody has come up with a method up to know,to intercept that data,as it is beeing transfered to the vehicle wireless by some kind of radio signal .
I can assure you,the car knows about every single tire pressure !
I have no idea why it's not beeing displayed as in a lexus !
It's rediculous when you think about it,as it not so that the car will use more fuel or lose EV-Range by showing it .
All it needs is an additional screen on the MFD !

 

It isn't the TPMS; it is what info the manufacturer decides to show you. Just having a warning light, like on my car, to show that a tire's pressure is out of spec is cheaper, than a display that shows which tire is too low, which is cheaper than a display that gives the actually pressure readings. Using the info display would save on those costs, but there is the cost of having someone program a tire pressure window for it.

 

I guess the answer is "no".

 

i don't recall anyone ever upgrading, maybe over in mods? would you have to replace the existing sensors to match the unit you want to use, and where would you mount it?

 

No additional display needed. There's already a big 11 inch display. Why not program an extra screen for vehicle parameters. My Ram pickup has a screen that shows all 4 tire pressures, one that shows the oil temp, oil pressure, engine temp and transmission temp. Or i can slide it over and display individual gauges. Very handy and very simple.

 

I think most cars are lacking in the info displayed department. While the previous Chevy did, my current car doesn't display coolant temp. There isn't even a vague analogue dial to let me know it's warm enough for the heater to supply heat. I understand that the overheating light is plenty for most drivers, but it is annoying none the less.

The warning light for the TPMS is plenty for me. If it displayed which tire or the pressure, I'd have to go to the dealer to relearn sensors after a tire rotation or remember that the front driver side displayed is actually the rear passenger and so on.

there is likely an after market display that will work with the factory sensors.

Toyota didn't feel the need to have a programmer do so.

 

This is an area of disappointment that I have with the latest generation Prius (2016 and 2017). In the past you could always count on Prius being a technology showcase, helping to offset the misconception that it is just an economy car. Ten years ago I was wowing people with my Gen II's backup camera, which most people at the time didn't even know existed unless they owned or had ridden in a high-end luxury car. The same with my demonstration of (3-door) Smart Key. Automatic climate control was at the time found mostly in luxury cars. And I would explain how my Prius was one of the first cars to include electronic stability control.

A few short years later I could add to my Prius-promoting spiel that you could now buy a Prius with HUD, collision avoidance, dynamic radar cruise control, lane keep assist, parking assistance, even a solar roof panel. All of which was quite cutting edge at the time.

Now in 2016 I can tell people that the latest Prius ......

The backup camera isn't even current anymore as it doesn't have the predictive (i.e curving path) feature.

No front camera? Come on!

I recently rented an Infiniti that had a realistic looking "helicopter" view of the car and the immediate surroundings. I found it extremely helpful during parking, it even showed which way the front wheels were pointed.

And the Altima that I recently rented had the individual tire pressure display that is the topic of this thread.

Of course I don't expect all of this to be included in the base package, but I just can't believe that none of it is available in a car that in the past could be counted on for cutting edge technology.

 

Prius. To Go Before.

Yet it doesn't even follow closely...

 

Yes it's ridiculous to have all that Pressure and Temp data, and not see it!
Rented a Cruze and that data was front and center.

You can of course see it with miniVCI and Techstream available for $25 from Amazon or EBay, and a laptop. Actually I use a desk top, which is way less convenient.

 

The MFD has 16 screens showing monthly and daily fuel consumption ,I would have gladly sacrificed one of them for a tire pressure screen !
