I have the same tool. I bought oem tpms sensors for my aftermarket wheels. Before I got them installed, I plugged in the tool to record my original tpms codes. I put on the aftermarket wheels and had discount tires program them for free. Brought the car home, plugged in the tool to pull the second set of codes .

Nice, I'll check tirerack offering, do you recall the brand of the tpms that you purchased via tirerack ? I'm also researching another solution which was offered to me by an online seller, basically you provide them with your original tpms IDs -the one you currently have on your car-and they clone the existing IDs on brand new set of tpms then they ship you the new set with clonned IDs which doesn't need any device/tool to re-learn or add to ECU , I find this great workaround because the new set are technically allowed to communicate with ECU and provide all guaging data .....I would love to hear some feedback if someone went this route.

Hi All,
After changing to my winter tires
the tpms light is blinking for a minute and after that it is on all the time.

Is there a reset button or is the reset only done in the menu TPMS.?

Thanks for helping

Blinking and then solid light typically indicates a fault in the system. Was a sensor possibly damaged during your switch?

Hi,

More specific. The system worked with the original wheels. When I swapped them to the winter wheels with new tpms sensors the problem starts.
The tpms program tool shows that the ecu was programmed right. It looks like that I have to reset
something. When I do the reset in the menu there happens nothing.

Or is there a special procedure to program the id's ?

Thanks.

Read page 588 in the manual. It seems there may be a procedure the dealer needs to complete to register the new sensors. Try the initialization process yourself and maybe that will domit.

I don't believe that re-setting/re-initializing the TPMS has anything to do with registering the sensors to the system. It only sets the pressure at the time time when the system is re-set to be the baseline pressure that the system will use to determine when to send an alert saying that a tire has low pressure.

I could be mistaken, but my understanding is that the system is only capable of having one set of sensors registered at a time, and if you use a second set of wheels with different sensors, the sensors on the set of wheels being used need to be registered to the system every time you switch wheels, and that needs to be done with Techstream, which means it would normally be done by a dealer unless you have a copy of the Techstream software. I don't know if registering the sensors can also be done with the Carista smartphone app, but it may be capable of doing so.

The way to avoid having to re-register the sensors every time you change the wheels would be to clone the second set of sensors from the first set of sensors.

When turn on ignition if blinking = need program. DO NOT press reset TPMS button It will make it harder to program if amateur work on TMPS tools
When turn on ignition if stay on solid = low air
To clone a sensor buy aftermarket brand like Schrader.

I just changed to my snow tires and re-programmed the TPMS for the winter tires, but there is no indication of which tire 1,2,3,4 correspond to.
Anybody know? Otherwise, I guess I have to inflate them one by one and check to see which tire registers the increase in pressure.

PeeVee

The system will determine by itself their locations, so the order is not important.

Usual

Any idea how it does that? I would have assumed there was only one transmitter/receiver in the vehicle.

PeeVee

It would at least have 3 and work like a GPS works, using triangulation.

Once the new TMPS have been calibrated and localized, if you use Techstream, you can see on the TPMS page for which wheel the sensor has been located.

I'm confused by this! Doesn't the tire pressure indicator on the dashboard indicate the pressure of each tire, ie, LF, LR etc?

PeeVee

When we program the TPMS IDs, they are in a list of 1 to 4. The list entries 1 to 4, they are not tied to a position (LF, LR, RF, RR). The vehicle sensors will read the location of them by itself. So when it read the pressure of a particular TPMS, it will use the detected position to display its measurement on the dash board.

Whenever there is a tire rotation, the wheel might not necessarily return at the same position, the vehicle sensors will search its position.

At the beginning of each season I personally switch the front tires to the back and vice-versa, but I don't change the order of the way I program them.
