TPMS Sensor Re-Learn ?

Is there anyway (other than using Alfa OBD) to force the TPMS system to relearn the sensors?

I changed back to the summer wheels and tires a few weeks ago and my 2019 Laramie 2500 diesel has never found the sensors. Everything was working fine with the winter wheels & snow tires (OEM rims/sensors) before the change over and I know the sensors are good as I can read them with my Autel TPMS tool. Display just shows 4 sets of "--".

If the answer is the only way to do it is to use Alpha OBD along with the security bypass harness, does anyone know if there is a step-by-step procedure (write-up) on how to enter the sensor information or cause it to relearn the sensors?

Just as a side note -- when I changed the tires and wheels (from winter to summer sets) on the wife's 2023 Longhorn 1500 Eco-Diesel (we refer to it as the "Baby-Diesel") it found the sensors almost immediately without doing anything.

Thanks,

Bob

 

Did those wheels work last year? As far as I know there is no need to do anything, even on rotations it finds where they are now. I do not have a 2500 though so no TPMS system only TPIS.

 

Sorry I forgot to include that info in the original post --- yes, the "Summer" sensors/wheels/tires worked fine when I took them off last fall and put the "Winter" set on. It found the "Winter" set without a problem (they are the originals/OEM sensors and wheels with Blizzaks). I keep waiting for it to find the Summer set but nothing so far.

 

I had the right rear TPMS replaced on mu 18 shortly before trading for my 24. It was OEM and took a few days before it was found.
