Hello everyone I am wondering if I can change my Lexus gs350 2016 tire pressure unit from kpa to psi... I could not find any option instead I only found TPMS reset.. If anyone have an idea please let me know.
thanks

 

I recall that it's not possible because as I understand it the car was built for delivery to a country that uses different measurements and it was programmed that way when built.

I remember someone having a GS 350 that lived nearby the Canada/U.S. border and bought the car in Canada or from a Canadian but wanted it to have U.S. measurements. I do not recall if he ever found a solution...

 

Just adding to discussion, not saying this is the solution.

Looking at the TPMS part numbers between US and Europe, the TPMS initiator and the drivers for front and rear all have the same part number. Not to say they can't have different programming.

When I connect an OBD tool it has overall settings to display units in US, metric or Imperial. This is before I even select the car type. So when I read TPMS pressure, it displays it in PSI or kPa depending on app setting. I wonder if what has to be changed is the cluster to gain access to the different unit conversion. To me it would make sense. The cluster is def something that is different between regions/countries, so to me it makes sense that it would just take whatever raw reading/measurement the sensor puts out, and just convert it as needed.

Again, just some speculation.
