Yep, I'd wait too...

 

I scanned them in the order all tools request. Starting with left front, right front, right rear, left rear. But after the relearn, and viewing location through Techstream, it showed the right rear ID in the left rear position and visa versa. So I then scanned left front, right front, left rear, then right rear. After that, Techstream showed the rear sensors swapped again. Only now the ID's are were they should be. Autel support says they think the sensors are the problem, and I should buy their MX sensors and program them. So now I am debating whether to buy a set from them, or go with the Densos from Rock Auto.
The tire light is not on. It's just the individual pressure readouts that are blank.

 

The OP was so sensitive, I think we scared him away?
If non-genuine sensor don't display tire pressures, then we must accept that.

 

That is a tough issue.
The genuine sensors could be faulty?
However, so much work to remove those genuine sensors [return], and install a set of aftermarket Autel sensors.
I would probably accept as is.

My personal experience with Autel sensors is that on cooler mornings, they take much longer to wake up.
Whereas the OEM/Denso sensors wake up instantly.
Hence, nothing is ever perfect I am afraid.
Furthermore, the aftermarket Autel sensors may no longer display tire pressures on your instrument panel.

 

I could be wrong but don’t think I’ve seen a Schrader fitment for our vehicles. Probably the wrong sensor. It will turn off the tire light but won’t show pressures. Also I wouldn’t expect the ECU to show the sensors in the correct positions until after it has received a signal from the sensor after the relearn process. After you enter all the ID’s into the ECU the sensors all need to be rescanned in order. Very rarely you will also need to go for a drive.

 

I just got back from the tire shop. I purchased a full set of the Autel MX sensors, and had my tool auto generate new ID's for each one. Had them installed, and everything is working now. I did notice that it does seem to take a minute or even need to be moving before the pressures show up. I really debated on whether to go Denso or Autel. I found the Autels at Nappa for $29.95 each. So it was a much better deal.

 

Does your GS350 instrument panel display tire pressures reading for the four tires when using Autel MX sensors with auto-generated ID keys?

 

Yes. They are back. I have only driven a couple of times since they were installed. I have noticed that they take a little bit to show up. So when I start the car, the pressures are blank. But they show up after the car is moving a little bit.

 

I wonder if you can clone the oem ID’s

 

Here's what one TPMS maker has said:

Vehicle relearn and sensor programming are completely different procedures. The issue stems from the availability of aftermarket TPMS sensors that come as programmable, universal or cloneable sensor units. Sensors must be specifically programmed with the proper protocol/application information for the vehicle before they can be installed, and then must be relearned to the vehicle.

Before the relearning procedure or sensor location assignment, apparently some vehicles have a specific protocol that must be followed - - unless the same brand and model of TPMS sensor units are used to replace the originals.

 

My Autel MX sensors, I used the simpler cloning technique, and everything works fine.
I also have the option of auto-generating a notional ID, or scanning, or just manually reading and typing in the stamped ID, but I have never tried these other 3 techniques.

However, my Autel MX sensors take a good 500+ yards of initial drivIng to activate before the orange tire pressure warning light switches off.

 

I've never had the orange tire pressure warning light come on in either the GS 350 or the GS 450h I've had. My air pressures always display within 20 feet of travel in my GS 450h.

As my GS 350 got older (and the original TPMS sensors got older too) it had a tendency to display dashes (- -) when the temperature turned cool/cold, but once warm weather returned tire pressures displayed within 50-100 feet of travel.

I'm not sure why your new Autel TPMS sensors react so differently from how Toyota/Lexus obviously wants the TPMS sensors to react, at least when TPMS sensors made by Pacific Industries are installed.

 

True, my old OEM sensors - the orange TPMS warning light never ever came on unless the tire pressures were low.
Perhaps the Autel MX sensors have more internal friction inside them?
Or the Autels simply take longer to wake up?

 

Perhaps so!

Knowing my tendencies and how OCD often takes over, I'd be replacing them with TMPS sensors equal to the originals made by Pacific Industrial - and hope they perform like they did when the car was new.

 

Glad they show the pressures but if the light comes on until you drive that’s gonna be a no from me dog. I’d order the densos from rock auto.
