TPMS reading through OBD?

[Sergio Big Dawg]

Newbie question here. I searched in the forum and wasn't able to find the topic in subject addressed.

In my 2021 Patrol Safari I got TPMS. The thing is that it shows only the alert in case the pressure is low, but it does not give me the indication on the actual value.

I was wondering if I could read the value through the OBD port. I also checked on that part of the forum and did not find anything.

I was hoping to leverage what the car already comes with, instead of replacing the TPMS and get an alternative system to read the tyre pressure.

The aim is not to use it during deflate time, it's just to keep an eye during the drive

The answer is yes, an OBD will be able to connect to the TPMS.  So far I've seen only one app with a functionality to connect to TPMS: MotorData OBD, and I've tried it in an Android platform.

thank you very much @Mario Cornejo! Any advice on the dongle to buy? I've read several stories about incompatibilities...

I think any OBD will do, I got the very basic ELM327 for less than 100 Dhs at Amazon.ae, it opens a WiFi link and works well.  But I think there are much better options, for example OBDLink MX+ or Autel brands, that might offer a better way to connect.

The purpose of getting an OBD, in my case was to monitor the temperature of coolant and air intake during the summer drives. I rarely use it these days.

** Edit:  however I am of the opinion the TPMS system could be better in the Patrol Super Safari and provide a way to display the actual pressure for each tire, not just the low pressure icon on the dashboard. So, your approach of using OBD is a great workaround.
