new TPMS, techstream and Macs?

[M1911]

Regarding cloning my existing sensors, my understanding is that they have to pull the tires off my current wheels in order to clone my current ones?

No. A TPMS reader placed next to the wheel reads the sensor ID. Write those IDs down and then use them while programming new sensors.

Discount Tire was able to read my IDs.
Toyota wanted to pull the tires off.
Bring those IDs to the Toyota dealer and you'll be golden. Assuming you can't get Techstream to reprogram TPMS' (I couldn't either).
It's ususally a 7 digit code, mostly numbers sometimes with few letters.

I have a 09 LX. Programmable sensors fit a very large array of makes and models and years. They also make slightly more expensive Programmable that have both frequency bands. The sensor angle is adjusted at install via a pivot and screw so they fit nearly any wheel.

A quick search on Autel site shows the 2016+ sensor as compatible with their standard product, the 315 mhz mx.

Sensors are really very simple to deal with.

I did break several oem while remounting tires manually, they didn't look damaged but they were reading incorrectly. So care should be taken. I attributes the install issues some have experienced at tire stores to this. Even with the breakage I am far ahead $ wise, I've mounted 13 tires bought 8 or 9 sensors. It's paid for all the TPMS stuff and the mounting tools.

I just ordered the TS408 programming tool and 5 Autel 433mhz sensors. $260 delivered. Will update progress.

The dual frequency or single 433.? I think autel says use 315s....duals will work too.

 

[Chrisleduc1]

You are correct -315s ordered.

 

[Chrisleduc1]

Well, Autel’s documentation pretty much sucks.
They sell the sensors in 315mhz, 433, and a sensor that offers both. Their documentation notes that they support the ‘18 LX570 with the 315 sensor. Well, that’s only half true. The LX uses the 315, but the 315s DONT actually work! You have to get the dual sensor! But there is nothing anywhere on their site that says as such. So now that I’ve paid to have the tires mounted, I have to decide what to do.

I was able to clone my OEM sensors
with their $125 scanner tool. I could either scan the OEMs and the clone the new ones or I could scan the OEM and get the IDs and then manually program the new sensors.

I can use the tool to read the current pressure on the new sensors, but my vehicle won’t read them. So
I basically have a $125 tire pressure gauge.

It’s about 15 seconds to work through the tool to select your vehicle and then 10 seconds to scan the old sensor and then 10 seconds to program the new.

But at least my new AR910 wheels look good. But now I have some rubbing issues as the AR910 has an offset of 25 (as can be seen from the pics) and when combined with the 275/65R20 Blizzak LT, my wheel well liners are not happy.

Did you push the button under the dash? I’m sorry I said 315s would work, they sure do on my 2009 LX.

If the ones you have would work on my 08’ LX, I’d consider buying them from you for my summer wheels & tires. I won’t need them until spring either.

I’ll want to learn this whole process then too.

 

[grinchy]

Autel site shows the 315 mhz sensors for all years of LX.

So the next thing is to compare the ids from the stock wheels with the new ids/cloned onto the sensors to make sure they cloned over.

It would also be worth it to check in with Techstream and compare the IDs in the car computer, though these should also match the stock tires.

I can't think of any reason they wouldn't sync. My tire stack is about 50 feet away, but occasionally one of those tires (they share ids) will register when I'm in the driveway. I keep those tires with 20 psi in them, so it will set off the dash alarm, as soon as I drive away the true signal will take over . . . what I'm getting at is you can roll over one of your oem tires, and it should register. Then get it off by itself, copy the id, and then go over to a tire on the car and overwrite.

In the beginning I didn't get far enough away from the tires, and was copying the same ID onto different sensors . . .

Worth a double check.

Did you push the button under the dash? I’m sorry I said 315s would work, they sure do on my 2009 LX.

I thought that all the button does is to allow you to set the pressure at which the warning light goes off?

No worries, not your fault at all.

I should say that the product is awesome. It is the literature that stinks.

With the TS408 handheld, I can read my OEM sensors in 2 seconds. I can get the ID off of them. I just need the sensor within about 4 inches, so you just push it up against the valve stem and it reads fine.

Then there are two options with your new sensors. Mine were already installed in the wheel and on the LX.
A. you can walk over to the new sensor and put the handheld up against the valve stem to make a connection with the new sensor and then manually enter in the ID that you want the new sensor to have, or
B. you can just hit a button and the handheld will automatically make a copy of the OEM sensor, in about 2 seconds, so that the new sensor now has the OEM ID. Same result as option A, just quicker.

Once either one of those are done, you can then scan the new sensor with the handheld and get the ID, pressure, temperature, I think one or two other facts.

So, I know that my new sensors are programmed. I can scan them and see the ID and the pressure, etc. I programmed them twice, using both options A and B.

My next step was to call Autel. That was horrible. After being on hold for about 12 minutes, I got a recording that nobody could take my call and please leave a message. Well, when you've been on hold for a while, and tuning out the pre-progammed messages, it can be easy to miss what was said, which is what happened to me. So after sitting for another 5 minutes, I hung up and called back. Same thing. I then called a few hours later and got through to someone. He did some quick research and said that the MY18 CANNOT receive real-time updates from the 315mhz sensors. The only thing the MY18 can do is turn on the low pressure dash light. In order to get the real time updates, you have to get the combo sensor. And he was very unapologetic about the complete lack of detail about this on any of tier literature.

So as I said, I can walk to each wheel, do a quick scan and see that I have the right ID and see the current pressure, etc., but I cannot get the PSI to display on my dash. I have not tried to if the sensors will notify me of low pressure.

Honestly (assuming they are correct and the dual mhm sensor will work), it is a really cool product. It would be worth someone buying the handheld, and then just passing it around to people. Once you clone your sensors, you really don't need the handheld any longer..

If anyone wants I could take a quick video and just walk through the process of doing one sensor.

 

[grinchy]

Oh I see. Thanks for the additional background. I wonder if the oem part also changed then to include the additional frequency. And then if the oem capability was also increased to can 10 wheels 2 sets be added?

I had sensors from a set of '15 or '16 wheels, and the Lexus dealer had to pull the sensors from my new wheels to use on the old wheels I was installing. I had not heard anything about being able to use 10 wheels.

But, I have noticed something odd (to me), I have not swapped out my spare, and it is not registering either. When I am in my driveway and the car picks up the 4 old wheels in the garage, I get readings from all 5 wheels; the 4 in the garage and the spare underneath. But if I drive down the street and restart the vehicle, I do not get the 4 news ones, nor the OEM spare. I can drive back up the street and re-start and immediately get all 5 sensors..

 

[grinchy]

I would think it would pick up the spare too. It would still throw a yellow light though as four sensors are missing. What you are seeing is straight incompatibility . . . I had some Tundra sensors which are definitely incompatible, they use a different length sensor ID and can't be added via techstream, or reprogrammed with my programmer (it only does branded sensors for Autel) they were just not identified by the LX, same as you're experiencing.

It isn't such a huge deal to swap out the sensors after the wheels are balanced.
Step 1 - use a floor jack and tie down strap to pop the bead (link in my build thread)
Step 2 - use a clamp to compress the tire so you can pull the sensor and insert a new one.
I can do a full set of five in about 90 min. The first time around it took a bit longer.
If you're in the return window for your sensors you could try this . . .

I'm sure you did this but when you programmed the sensors did you choose the LX profile for your year? I assume that since you talked to Autel this was a given.

 

[unclemat]

Did you ever get these sensor to work on your 2018 LX?

We now, at least for the LC, that 2008-2015 sensors are not compatible with 2016-2021. Autel claims their MX sensors work for all years. I read here they told you only the dual frequency would, but that sounds like BS maybe? All LC/LX years use 315Mhz sensors; they just different some (protocol?) and are incompatible.

I'd like to have a sensor that works across all years as it would facilitate sharing wheel between my older and new 200.
